    Abstract: PROBLEM TO BE SOLVED: To provide a method for purifying or isolating 2,3,5-trimethyl-p- benzoquinone by surely removing intermediates and by-products formed during production of the compound and avoiding degradation of the component by diminishing the thermal stress caused by the treatment by separating the compound by the crystallization. SOLUTION: A method is provided for purifying 2,3,5-trimethyl-p-benzoquinone (TMQ) or isolating TMQ from a TMQ-containing mixture by separating by crystallizing preferably at -6 to 32 deg.C. A TMQ-containing mixture to be purified or TMQ contains TMQ preferably at 1-99.999 wt.%, more preferably at 90-99.999 wt.%. The TMQ-containing mixture is formed preferably by the catalytic oxidation of trimethylphenol. TMQ is a useful intermediate for the production of trimethylhydroquinone which is a precursor for the synthesis of α-tocopherol.

    Abstract: Preparation of cyclohexanetrionecarboxylic acid thiol esters of the formula I in which R and R represent optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, benzyl or phenyl, and R additionally denotes hydrogen, by reacting a cyclohexanetrione compound II with hydroxylamine or hydroxylamine O-sulphonic acid in an inert solvent at temperatures from 0 to 150 DEG C to give cyclohexanetrione compounds III subsequently reacting the compounds III with a mercaptan IV R -SH IV in the presence of an anhydrous acid HX to give cyclohexanetrione imidothioester salts V where X represents the acid radical, and hydrolysing the compounds V to give the cyclohexanetrione carboxylic acid thiol esters I.
