      PCP AND LOW MELTING POINT  Bookmark   

This Bee had a dream 2 weeks ago.

You see, this Bee use to purchase every chem from a store but his beloved Piperidine.  Which he acquired from friends.

4 years ago, this all changed.  These same stores no longer gave him love.  So off he went to his piperidine friends.

Lo and behold, they were able to get every thing this bee needed!  but they all came in plastic gas cans. hmmm,  this bee's only concern was on wether or not these chems were old, dirty...not if they were in fact the chems themselves.  he was sure that they were.

this bee mixed his PCC with his Phenyl Magnesium Bromide.  A beautiful and familiar result came back.  This resultant was then crystallized and let to sit 24 hours.

24 hours later, nothing came back.  this bee waited another 24 hours and he was rewarded for his patience.  Or so he thought!

This crystallized product had a low melting point.  it melted at room temperature.  NOT COOL!

This bee recrystallized it to no avail.

This bee tested said product and had wonderful times if only he could remember them!  ha

but now this bee wishes his fellow bees would help him in solving this mystery.  Why the low melting point? hmmm

How can this bee improve the melting point?

Maybe there are too many impurities left in the product...

This bee knows his numbers are correct so the method in which he created this product are 100% correct.

Thanks and enjoy the new year!

You only describe your product as having a low mp - what was your expected mp, and what was the measured mp? Was the measured mp broad (as in melting over several degrees range), or sharp? Is the compound active, and giving the expected effects? Was the mp of the PCC used in the synthesis correct?

Are you sure about the identity of the chemicals you used to create the PCC, and that of the Phenylmagnesium bromide?

If they for example sold you p-tolylmagnesium bromide instead, then your product would be pure and psychoactive, but exhibiting another melting point, as it wouldn't be the correct compound.

thanks rhodium!  first time poster, long time sideline watcher

i guess what i'm gettin at is the product is melting at room temperature.  and i dont know why.  i'd like to be able to fix it if possible but not sure of the ways in which to do that.  this is where i need some bee expertise.

the compound is active, agressively so, and thats what is so frustrating.

any ideas or thoughts would be greatly appreciated

You have not answered any of the other questions I gave you, therefore I have limited ability to help you out.

unfortunately, i did not have an expected melting point.  i have never run across this so it was never an issue.  i only want it to "not melt" at room temperature.

i also haven't measured the melting point of the compound, i only know that it melts too easily.  pcc melting point didn't *seem* to be an issue as it retained its solidity.  it may have been a little wet instead of the preferable dry.  hmmm

the compound was active.

only the bromobenzene, piperidine, sodium cyanide, some of the ether and cyclohexanone came in its original container.

please excuse my crude, non-scientific criteria.

if its mixed with another batch of pcp, it stays together as it should.

i'm wondering if its because the pcc was a little wet instead of dry.

Strange thing that the melting point rises when mixed with pure PCP, I guess that rules out that it could be another analog. I think you should vacuum distill the freebase, that should bring it to the correct mp. Use a short air-cooled condenser to avoid the distillate clogging the condenser if it solidifies already there.
