Abstract: PURPOSE:To prepare the titled compound useful as a raw material for the production of amino acids, in high yield, by adding and reacting an indole compound to a reaction system producing pyruvic acid from tartaric acid in the presence of cultured product of microoganism capable of converting L-tartaric acid to pyruvic acid. CONSTITUTION:The objective compound can be prepared efficiently, by adding and reacting indole and/or its derivative to a reaction system to produce pyruvic acid from tartaric acid and/or its salt in the presence of cultured product (or its treated product) of a microbial strain (e.g. Pseudomanas putida ATCC 17642) capable of converting L-tartaric acid to pyruvic acid. The indole and its derivative is e.g. indole, 5-hydroxyindole, 5-methoxyindole, 5'-chloroindole, etc.

Abstract: PURPOSE:To obtain the titled compound useful as an intermediate for agricultural chemicals, medicines and dyes in high purity by easy means without problems, e.g. incapable of distilling due to the sublimation, by the azeotropic distillation of crude phenazine with diethylene glycol as an entrainer. CONSTITUTION:Crude phenazine obtained by the reaction of 2-nitrodiphenylamine in the presence of an alcoholate, dehydrogenation of 1,2,3,4,6,7,8,9-octahydrophenazine, etc. is subjected to the azeotropic distillation with diethylene glycol (DEG) as an entrainer under reduced or ordinary pressure at 130-240 deg.C, preferably under reduced pressure at 150-200 deg.C, in a distillation column to take out the azeotropic mixture of the phenazine with DEG as a vapor from the top of the distillation column, and the resultant mixture is then cooled to 50 deg.C or below to deposit the phenazine as crystals. Thus, the crystals are separated from DEG to give the aimed purified phenazine.
