swim's gotta use a lava lamp for a HI reaction, the problem is the base of the lamp flask is flat... swims would like to try a small reaction first so that if there's a balls up, not to much precursor will be wasted, its a 25W Lava Lamp, swim would like to try a 3 grammer first off, any suggestions? maybe the Lamp base is not adequate? cheers

never done it myself with a Lava lamp..but a 25W is good for up to a 10grams reaction...according to the theory...for 3g it should do the job...

yeah, apparently the heat is sufficient, just wondering bout the base though

also, could a hose connected to the top of the lamp flask (2ft length) with a balloon taped to the end work? has anyone tried? its not exactly condensing quality but fuck, i gotta use what i got, just worried that the gas it emits might eat through the hose/balloon, thanks

ffs.. the lamp only heats water up to 54 C!, how the fuck is that meant to complete a rxn? (25W)

90 Celsius is sufficient however you want a temp of slightly over 100
Celsius inside flask, anywhere from 90-120 is fine though, lower the
temp the longer the cook time needed.




some people have tried it and report good results...this is wet reaction .

.for small reactions like this I like to do a semi dry reaction using a few drops of oxigen peroxide instead of water...

yeah, 54 wont cut it though, or would it? swim doubts it, not from what swims read, might try a 30W'er, its only for a 3grammer, so hopefully

No, 54 C would not do the reduction in a timely manner, if at all. As amenselah stated, over 100C is preferred for a wet reflux (LWR). For faster drier reactions, most prefer higher temperatures.

Well one can achief higher tmps by panting the bottom of the glassflask with
heat resistent black colour ( thick ) or cover it with alufoil , so no more energy is unused and goes just through the glass heating the water ... to some extent
but the lavalamp is constructed to heat hup to a certain levl and keep this for
any longer time it stands in a room with same tmp and humidity , when doing
wet reds only the bottom of the flask is covered with more heat absorbing chemicals than water ...

Should work too as long as it is thick enough , just try it
Since alufoil is everywhere avaialble its the stuff of choice ..

swim put just a little amount of water into the lamp flask, then tested the temp after a couple of hours, went up to 80.1C this time

hmm still not good enough , for fast and sufficent reduction od the
pseudo , i think a complete reduction could be achieved but it would take a least 2 days , try gettin a better lamp( not a completely new one just the lamp ) ( 25 is is not that good have one myselfe but gets to 98 ° ) with 30 -45 watts that fits in ur lavalamp and provides enough heat ...

swim will have too, as the insulation from tin foil reduced heat, swim mustve fucked up somewhere because its been said to increase heat, this is not the case,
