CurbShots Nanoscale synth Any thoughts on thisone?

BuseyBee · Thu Jun 02, 2005 12:14 pm

This synth has my intrest cause im new,broke and dont wanna throw in alot of my precursers before im shure im gonna get them back.that said ive heard that the 4 drops of hydrogen peroxide will oxidise the red p too much and i was told to substitute the H perox for 4 drops of dh20...is this a good ida?
ant additonal comments or sudgestions would be appreciated.

Curbshot developed this super scaled down method as a means of familiarizing novice cooks with the
subtleties of the reaction. It is definitely maximum expertise with minimal investment - Two stacked soup cans
comprise the receptacle for the heat source (candle) and reaction vessel (test tube) Specifically designed for
use with matchbook phosphorous and tinctured iodine crystals, it will about 0.7 gm and requires little in the
ways of ingredients or supplies. Excellent synth for experienced cooks who are short on resources. Curbside
says not to deviate in any way from from directions Total time from start to snort is 2.5 hours. Many Hive
members report accomplishing it in a .little over an hour! Mmmm mmmm good.

1.5 gm. Pseudoephedrine3-Test Tubes (or cigar tubes)
2.0 gm. Red Phosphorous2-Tin Cans )8 oz.)
3.0 gm. Iodine Crystals1-Balloon (standard Kid size)

Electrical TapeCandle (short)
Measuring Cup (US/Metric)Distilled Water - d-H2O
Hydrogen Peroxide Muriatic Acid
SandEye Dropper
Alarm Clock/TimerScissors
FunnelGlass Ash Tray
Razor Blade Gram Scale

Punch/Drill air holes in one of the tin cans. This will hold the candle - your heat source. Fill second can with
wet sand and place on top of first can., This provides an even heating surface as well as a receptacle for the
test tube which is where the reaction will take place. Finally, place test tube in freezer 5 min. prior to start of
synth.

Synthesis

1. Remove test tube from freezer
2. Add Iodine, Ephedrine and Red Phosphorous (in exactly that order);
3. Add 4 drops Hydrogen Peroxide
4. Immediately place balloon over top of test tube (1 cm. from edge) and tape securely.
5. Shake vigorously while keeping thumb over top of tube to keep anything from entering balloon.
6. Place tube 2.5 - 3.0 in. deep in Sand.in Can
7. Heat for 1 hour
8. Blow out candle and let cool for 15 min.
9. Using scissors, cut off balloon.
10. Add 20 ml. d-H20
12 Shake vigorously while keeping thumb over top of tube.
13. Saturate a Coffee Filter with d-h20 and place in Funnel. Place funnel on top of 2nd test tube .
14. Pour (filter) contents of 1st test tube into 2nd test tube.
15. A clear-yellowish liquid should remain.
16. Mix 8 gm of Lye & 20 ml. of d-h2O in a clean test tube.
17. Shake vigorously while keeping thumb over top of tube (caustic - wear gloves)
18 Place in sand to cool.
19. Add 50 ml. lighter fluid to original reaction test tube (with yellow liquid)
20. Into this tube, add lye solution.
21. Cover hole with thumb and shake once.
22. Place in sand for 15 min.
23. Pour off top layer only into empty clean test tube.
24. Add 20 ml. of d-H2O.
25. Add 4 drops of Muriatic Acid.
26. Shake hard.
27. Use eye dropper to pick up bottom layer.*
28. Drop liquid into ash tray.

After liquid eavaporates, residue will be app. 0.7 gm/ of pure crystal ----, Scape with razor blade and enjoy!

*You may need to attach a short length of aquarium hose to dropper so that it can reach bottom of tube.

If the RP is clean enough there will be no need for hydrogen peroxide to be added, just a small amount of distilled water and a little heat should start the reaction nicely.

Have a look at placebo's method and also wizard x's method.

Curbshot's information on E extraction is very out of date and will not be very successfull on the newer pills (US)

zub · Thu Jun 02, 2005 7:28 pm

forget this one completely.
small scale is a good way to start, but not like this.

SWIM has successfully completed HIRP redcuctions many times in the past (but has no use for them, now). SWIM read the Curbshot Nano and thought, "Wow! This is neat", and decided to try just for kicks. The E was super clean, P & I were lab grade. From what I was told, SWIM followed the instructions exactly and got nothing. Everything looked right before the extraction was done. SWIM wanted to follow the instructions exactly, so nothing was changed the first time. SWIM also told me that he/she tried a second time and used VM&P Naptha instead of lighter fluid and failed again.

At this point SWIM didn't want to waste anymore precursors, so he/she didn't waste anymore time with this synth. It should be noted that SWIM did not have experience with the "titration type" extraction that was indicated in the procedures (but again wanted to follow the procedure exactly). SWIM recommended to anyone that tries this: Do not use Hydrogen Peroxide (use dH2O), and after adding the lye, watch for a change in the non-polar (lighter fluid or naptha). From larger scale experience, SWIM says it should look clear before adding lye, but different after adding lye. He/she also said that he/she would gas the non-polar with HCl gas instead of titrating.

I hope this helps. SWIM is vague in his/her descriptions and hasn't done reactions on eph. in years. BuseyBee: You may find only a small amount of information about this type of reaction here at Synthetikal, as it doesn't seem to be very popular, here. I would suggest that you post your question at http://www.wetdreams.ws and see if you get any replies. This type of reaction is popular there (maybe not nanoscale).

In complete agreement with zub and DrugPhreak, I don't think this is good for the first time (or good at all, for that matter). SWIM would suggest starting with more precursors. That way it is more forgiving to mistakes.

DrugPhreak: You seem suprised at the 1 hour reaction time. SWIM has seen many reactions finished in just over 1 hour. Usually 1 hour 30 minutes was more than enough when a .5/1/1.5 ratio was used for less than 28g precursor(E). The excess I & P finished the reaction faster, and P & I are cheap. SWIM said this never seemed to hurt the yield or the quality, as others have indicated.

Those days are over for SWIM, anyway. This is a good reaction for newbees. It is quick, easy, teaches A/B and other basic chemistry techniques.

Final Verdict: Don't use Curbshot's Nano

curbshot eulogy:

i have no doubt that this worked for old curb, bless his heart. and many others.
its unlikely to work for a novice, nor produce anything remotely pure.
times have changed.

should one encounter or develop clean precursors and a handle on extraction, then one would want to go the next step along the way.

which is what?

probably gaining more knowledge of what is actually taking place, so that one might "punt" when things don't go exactly as prescribed by various god's of ----.

and they almost never will.

(same like carpentry)

Hey guys, this has been a big eye opener to Swim, the people on this page seem a little out or my legue when it comes to chem synths. So you think i would be waseting my time huh?
what are you thoughts on AcidMelts Slacker Synth?if your not familar with this ont then i could post it here .anyway is the Slacker Synth worth a damn?

loki · guinea pig

nano scale sucks because it's hard to get everything pure, imho, 7g is the minimum size that should be done. i know it's a pain in the ass, but it's worth the wait required to pull everything together. Besides which, swims tend to wipe out the results of a 1-3g cook in a matter of a week or two.

also, the longer cook is better, org always said 4 hours. phosphoric acid (80%) is a good thing to add to it to get everything moving around more.

and yeah pills are a pain now compared to 4 years ago. a preparation with 120mg in a two dose repeating slow release are easy to clean up according to swil, he's posted a thread about it, at the top of the thread is described a version which got a good 800mg out of 1.2 theoretical present in the pill, should be able to get that result up to 1g with some optimisation.

any idas on Acidmelts Slacker synth??
it it a good one?

Soap · Fri Jun 03, 2005 9:57 am

swim is in the same situation as many bees. hes finishing up a much larger project but cant because of funding... so he wants to make some ice to get back on track.
he succesfuly extracted a g of e from a pack of 120s hes got about a gram of rp and plenty of iodine but he cant find a good method. he was tempted to try the curbshot nano procedure but after reading this thread... hes thinking otehr wise. what does every one think of the same amount of percurser is a 50ml flask on an oil bath with a 6 bulb alihn heald at reflux for 3 hours? a laq of solvent could be an issue here so maybe adding some h202 might help? or as said before maybe some h3p04...

loki · guinea pig

ya phosphoric acid is good.

only need 1/3 of a g of rp for a g of e. and I2, about equal weight as e

as for method - chuck in flask, add a few drops of water, put condenser on, ballon on top to retain gas, reflux for 2-4 hours, workup

loki · guinea pig

ohh

of course, be careful with the heat initially, too much and it can go off real fast. swil's best solution is to put rp and e in flask, in the freezer, cool, then add the i2 while it's cool, nice gentle start.

do it for 4 hours, gets better octane...

but as i said, small sucks... but still, i guess a week of tweak is nothin to sneeze at. its just hard to get good returns on such small amounts, with no scales, results are only moderate purity.

ya i can definitely agree with the thing about getting precursors right. might as well not even bother if your pseudo isn't decently crunchy crystalline stuff, preferably white/transparent, but that takes a bit of work (well, dry acetone/mek and dry ipa). same goes for rp, gotta get it clean, one cannot go overboard cleaning that.

regarding that, btw, rp is dense, weighs twice as much as pfed (to compare them both as finely ground powders), a lot less than it looks is needed, best to weigh, but i think volume is decent, about 2/3 of the ml volume of the powder is roughly the grammage. also, good rp is very fine. filtering it is a bullshit way to clean it. boils followed by settling and decanting are very good. Also, rp behaves funny in acidic solutions, after acid boils, neutralise with NaOH solution. in the acid it seems to want to all form these clumpy things, and is no good for settling and decanting, but in base it falls down as fine powder. good clean rp is red too btw, if one gets rp which comes out too brown it's shitty, something else in it, i dunno what tho. cheap brands are not neccessarily better, they usually use more ground glass in the strikers... looks like more, but it's actually less. not enuf rp and the rxn don't work.

iodine is not so fussy, a bit of trace residual HCl in it is not gonna kill the rxn. similar to rp, it's more dense than pseudo, but not to the same degree as rp. too much iodine makes for an ugly workup, a lot more base is needed. swil found that a pair of phone books, an old news paper and a bunch of filter papers wrapped around the filtered crystals works great for drivin the water out, jump up and down on that bitch for dear life. STOMP IT HARD.

just offerin swil's advice from workin on the nano scale. swil is glad to be leavin nano behind tho, but it was good in some ways.

A lot of clanchemists cut their teeth on this rxn, it's a good way to learn the basics of synthetic chem. those who don't go to university i mean.
