    Separate GBL (gammabutyrolactone) from benzyl alcohol?

    Question 
    Noob chemist here...I found a OTC paint remover product that is mostly benzyl alcohol but has 5-10% GBL content and 10% 2-butoxyethanol. Since benzyl alcohol and GBL have almost same boiling point, distilling isnt really an option. I dont care about the GBL too much so doesnt matter if it gets...

    What's the cheapiest way to synthesize GBL

    Question 
    Hi comrades, I found a way to make GHB, but I don't want any problem with the justice of my country, so I need to synthesize GBL first to stay in law I found a way with1,4-Butandiol, but I don't found the detail of the preparation have you any method to synthesize GBL for not much money

    Dehydrogenation of 1,4-Butanediol (BDO) to gamma-Butyrolactone (GBL) HELP!!

    Question 
    Hello everyone, I have a question for the experts i have a copper chromite catalyst and BDO. But everything I read about this synthesis is you always need to purify the BDO before you use it to convert to gamma-butyrolacton and you need to purify the GBL afterwars because it containes some...

    Can someone please help me with this 1,4-butanediol (CAS: 110-63-4) --> γ-butyrolactone (GBL) (CAS: 96-48-0) conversion?

    Question 
    1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL). In the presence of phosphoric acid and high temperature, it dehydrates to the important solvent tetrahydrofuran.[7] At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form...

    Gamma-Butyrolactone GBL/GHB

    Question Looking for a vendor 
    The goal in mind is to obtain GBL or GHB. Anyone reading this knows all the problems that come with that. So, looking for some help. So my customers do not like BDO, when I say do not like, I mean they HATE IT. They however seem to love GBL & GHB of course (who knows) Anyways, we all know its...

    1.4-butanediol (BDO) - How to Convert to GHB??

    I have pure 1.4-butanediol (BDO) it's frozen at 20.1c so I know it's pure stuff. When i melt BDO and take 1ml or 2ml no affect! I THOUGHT it changes to GHB in the body when digested...but has no affects at all.. Am I meant to add or do something to the BDO to make it turn to GHB inside the...

    Is there a market for GHB in the under 27 straight demographic in the US, Central Europe & Australia?

    Question 
    It seems easy enough to make from non-watched precusors in both locales but seems confined to older gay men & unsavory date ***** types. Is there something to be built here?

    GHB (Gamma-Hydroxybutyrate) Synthesis FAQ

    Introduction. This file deals with the synthesis of GHB and related compounds. It is highly dangerous to attempt a synthesis of GHB without the proper knowledge of practical organic chemistry. The far most simple way to produce GHB is by the hydrolysis of the corresponding lactone (a cyclic...
