Turning pse fb to pse hcl

[buff_core]

Good afternoon everyone, a very basic but overlooked question via the search engine ect, Swib has wasted many a good ingredients due to the last step of the stb3 method, can anyone point me in the right direction or give any help?

Best wishes
Swib

at the last stage of the stb3 when swiy adds the lye solution and pulls the pse freebase with napatha the last stage it to add hcl to the pse to form the hydrochloride salt of pse this can be done with gassing or the tiltration method in the search function type in tiltration or hcl gassing this will put you on the right track

[dpayne]

Gassing is actually something that swid found was never easily searched easily on the forum and documents from other areas were needed to be obtained to totally put into perspective and then only by links at the bottom of search result threads did swid find links to other threads with relavant info so since this is current and a problem which swid can relate to bmk I hope ya dont mind if I hijack this thread with a litle text file that just came to mind.

STBIII will produce psuedo eph base.

Usefull for Birch reductions but for Push/Pull or Reflux PSUEDO FB must be converted into hcl.

How? You will need apply a A/B reaction to Pseudo fb (Fb= Free Base) which is currently in the freezer.

Xylene or Toluene
and either
Damprid and hydrochloric acid
or salt (NaCl) and sulfuric acid

Dissolve Psuedo in non-polar solvent V&MP - naptha will work if heated
Bubble HCl gas through the top of the solvent until the pseudo-HCl salt falls out of the solution, then decant/filter and dry.

Bubbling is acheived by
- filling a small container will CaCl and place a stopper with two holes into the top of the container.
-Then place a 5mm tube just into one hole, running the other end of the tube so it is just barely submerged into the beaker with the NP solvent and Psuedo.
- Now take an eyedropper with HCl and place it into the other hole.
- Slowly drip the HCl onto the CaCl to produce HCl gas.

Notes

Don't place the end of the tube far down into the solvent or the solvent and pseudo will end up getting sucked back into the CaCl. Remember, just barely submerge the tip of the tube!

Sulfuric acid and salt can be used in place of the HCl
- NaCl to produce HCl gas. This method generates the gas very slowly where the HCl - NaCl method generates the gas the instant the HCl (L) comes into contact with the NaCl.
-Therefore the eyedropper hole is not needed. Just dump the acid and salt into the container, cap with the stopper/hose and swirl.

Or from Worlocks Archive

Salt of ephedrine Slower safer reaction
Again Add Water - about half as much distilled water as fuel / ephedrine to the separatory bottle
Then add 30% HCl(muriatic acid) to re-make the Ephedrine HCl salt - about 4-6 drops HCl/gram of sudo, this moves the ephedrine down into the water layer
Shake
Check water to pH between 7 to 8
Separate, place water/sudo in evaporation bowl.
Evaporate away the water
Discard the fuel layer
Too much acid
If you add too much acid - pH less than 6, do NOT try to adjust with lye, you will end up with a major amount of salt
Go ahead and separate the layers , evaporate the water, you will smell the very strong HCl gas boil off near the end (don't breathe too much of this), when you have the solid, then let the pan cool, add acetone, crush up the crystals. lett it settle then pour off the waste acetone through a filter, try to keep the crystals in the bowl and rewash.
crystals with acetone until they are white
Acetone Wash
Powder the pseudo
Put cold acetone on the dirty sudo, , pour off excess acetone into a filter
this will remove some oils and excess acid. Acetone really cleans it up nice.
Vaporize a sample of the crystal E look for residue, rinse with acetone again if needed.
Always keep the acetone sealed or it will absorb water, once the acetone contains water it will begin dissolving your ephedrine and chili and you loose product
Acetone is the most dangerous of these chemicals because it is a fire hazard. The acetone vapor will crawl out of a container and flow invisibly along a counter top until it hits fire then Poof a hot rapid fire begins

The first part is a copy and paste of a thread or two and some other information swid once found here and then edited into a format that allowed it to be put into perspective. The second was later from worlocks archive which was sorta hidden and overlooked. Maybe someone could take the time to verify this for swiD sake and buff_core as its only an interpretation/ journal of a complete theoretical noob and could be not even close. If anyone would like to claim ownership or direct to the source please by almeans swiD again using the search can not find it and many a hours have already been wasted.

Swim's friend never adds any water to the solvent/fb - only adds the HCL drops and shakes like hell till it looks about like applesauce consistency. Squirts out on plate or bowl and it dries fast. Then washes in acetone, dry, and smoke. Tried adding water once but after long evap it didnt taste good or burn clean either. Is adding d-h20 even necessary? He never once added water. Is that just an easy half-ass way around not checking for correct ph level? Swim thinks that the yeild would suffer without using any water, and 2nd pull etc would have really low ph from too much acid. Doubt they will ever change ways, but what should swim tell his friend?

munchichee added 3 Minutes and 16 Seconds later...

Swim was referring to the fb chili, not pse. but still same A/B process applies.

This CAN be avoided by using one way valves in the tube going into the solution being gassed. Buy them at fish aquariums and put them in line. Also add another one, facing the other way to let air into the CaCl and HCl container. This way the container can be 'squeezed' to gently allow a stream of gas into the to-be-gassed solution. Get it? Got it! GOOD!!!
