No evaporation doesnt yield the solid rocks. It yields a crystalcake of small needle-like crystals indeed.
Tried freeze method and yielded bigger shard-like crystals like i posted before, but still.no rocks...
Yes washing after is prefferable as the oil is going to contain less contaminants.
But ye i also know people who just yank the oil straight into the reactionvessel after conversion.
White powder starting material was this test, i also have sample from yellow waxy lumpy powder.
Swim will do a small testconversion tomorrow also on phosphoric acid...
Thats what i think too, its only 1,5hrs and the hcl is very diluted with water and there is also caustic to neutralize a part.
Its not like with 5449 that needs 5 hrs with stronger solutions
But if someone has xp with this let me know, swim starts saturday conversion
Totally different question about this conversion... Hope u have an answer
Swim is going to do this conversion but his ptfe stirring rods for mixing havent arrived yet.
Can he for once stir with a 316 steel stirrer for once maybe for 1.5 hr? I know the hcl eats away the 316 but doesnt matter...
Swim too is familiar with this problem, doest seem.to crystallize. Even after trying to recryss, it keeps coming out thick and oily.
It is active as fk though...
