lugh, i apologise for me asking such things I knew already about, but this community faciliates a tendency in me being lazy! 
Without I would have probably already have made some Et2O on my own, and a good amount was also made now, costs were less then a 20th of bought one. I also knew already about the properties of DIPE regarding peroxide formation 
Just wanted to know about the schlenk equilibrium but figured it already out even if its not of use now anyway.

For DCM, i was talking about acidic solutions and its not really an emulsion im talking about there?

Oerlikon, your diacetylmorphine is nearly insoluble in anything beside methanol and aromatic hydrocarbons, so should be easy to figure out i guess?

Color tests for indoles from Smith's Psychedelic Chemistry:

Identification of Indoles
Keller Test

Add a little of the powdered substance (about 0.2 mg to 1 ml glacial acetic acid containing 0.5% FeCl3, layer underneath with 1 ml concentrated sulfuric acid and shake. The color varies with the indole, being olive green for psilocin and red-violet for psilocybin.
Van Urk Test

Prepare Van Urk reagent by adding 0.5 g p-dimethylaminobenzaldehyde, 100 ml water, 100 ml concentrated sulfuric acid. Dissolve 1 mg substance in 1 ml ethanol and mix with 2 ml Van Urk reagent and illuminate for 10 minutes with an ultraviolet lamp (black light). Psilocin gives a blue-grey, psilocybin a red-brown color. Colors produced in these two tests by many indole derivatives are given in HCA 42,2073(1959).
Quick, Easy, On-the-Spot Test JPS 56,1526(1967)

Saturate strips of filter paper with 2% p-dimethylaminobenzaldehyde in 45% ethanol; air dry and store in tightly stoppered amber bottles (or keep in stoppered container in dark) which will keep them useful for several months. Put a little of the suspect substance in a few drops of ethanol (gin may do, but do a control), wet a filter paper strip in this and allow to dry. Put one drop concentrated HCl on the dried paper (don't let it touch anything). Alternatively, the powder can be placed directly on the strip and the HCl dropped on it. A violet red or violet blue spot indicates indole derivatives such as LSD. With DMT or psilocybin the color is redder. The color must be observed soon after adding the HCl since it rapidly changes.

 

yes because it is 1-(c6h5 so phenyl or short phen and 1- because its on 1 which is N in most cases if present, for example look at indole, then ch2-ch3 or ethyl which, because it is the last substituent in the naming of this group precisely and has then phenylgroup on its second carbon, so there a 2-.

addition: wtf is going on with the 4-? it is because it is named for for the 4- position of piperidon, because if oxygen is present too than thats primary in counting, like in phenmetrazin or such.

another name maybe could be n-(4-piperidinone)-2-phenylethylamine?

Stupid question maybe, but Ive found numerous descriptions.

What colour is anhydrous reagent grade  Ferric Chloride, quality enough to use as Friedel-Craft catalyst?

  Ive come across some very dark brown chloride,with flecks of caramel, but it isnt exactly what Id call green/black,(purple depending on the light) as per most descriptions Ive seen and its in the form of fine powder as opposed to crystalline.
This stuff does fume somewhat when open to air. Ive attempted to further dehydrate a sample in a stream of dry HCl with no noticable colour change.

Anyone with real word experience?

It's a dark brown powder, and the preparation has been discussed in:

best way to dry it out?

Your question is almost incomprehensible, and it's clear your understanding of this language is minimal  The best way to dry it isn't mentioned due to the expense involved  The attached documents from the Organic Syntheses website  and Wikipedia explain the relevant facts very well   You need to reread the threads you're quoting from many more times, and start looking for more sources of information online    The information you seek is available in other languages   Bright Star has a PhD from a prestigious university, and his method to mdma isn't exactly crude as it has worked for thousands of members    The end results from the effort applied 

2nd batch turned out much less "wet"...let it boil longer. After that, had a chance to read lugh's attachment, interesting indeed. I think the key words left out of Rhodi's photo essay were "until crystals begin to form on the surface".  Although, now looking back, they can be seen in the picture.


So it would appear that Brightstar method=crude, the rhodi method pretty darn close, and the winner would be organ syth vol 1 pg 347>>>

only trick is how to centrifuge?

3rd batch brewing. will boil til crystals form on top.

How essential are the the chloroform washes?

also...brightstar says 4 hours, rhodi says 3-4, luhg's ref says 5-6, jon says 6>>>sounds like a choose your own adventure>>>

Consider you have to do the beckmann rearrangement before the hofmann rearrangement can take place.
About the time, i think it can be done in less than 2 two days if every reagent is available, but i dont know for sure.

as a rule of thumb, use 2 times a tenth of mother liquor volume and the third time one part on twenty suffices. Just let every layer sit long enough, and avoid an emulsion.
Also, dont use IPA, better suited would be hexane or toluene/xylene, IPA has to be salted out afterwards otherwise its completely miscible with water.

Well, tell your dog he should add some suited drying agent

Yeah he already told me that he would do it!
Can you tell me how much he would need to get 1 liter of xylene free of H2O, or is there some way to see it is free of H2O?

Xylene and water form a lower boiling point azeotrope:

You need to start learning about practical organic chemistry from textbooks instead of posting such questions:
