    Any idea why nothing precipitates out of a solution after a reaction with 120ml GBL and 86g KOH. Reagents were 99.96% GBL, 99% ethanol and pure KOH. KOH was dissolved in ethanol, GBL added, heated on stirring hotplate, allowed to cool, put in freezer and repeated. Once it worked this cycle but twice it didn't. Solution is still pH 10.1, almost seems like the reaction didn't occur, solution went up to 60C on it's own after initial mixing though. Any ideas?

    Cause you don't have GHB?

    I don't know the reaction you're talking about, but maybe you can read your thread title and guess: someone sold you a suspension of K ? Just a wild guess.

    The reaction eventually happened, the the G precipitated out but only after several cycles or heating and cooling.

    When KOH (dissolved in ethanol) is combined with an equimolar amount of GBL, a precipitate of G should form pretty much immediately.

    All reagents were pure.

    I was hoping that someone else had a similar experience, and a solution. Since this eventually worked, maybe the lesson is to do a few cycles of hot (70C) and cold (-5C) before you assume it didn't work and throw out your batch.
