| titleOfInvention | Method for producing lower alkyl pyruvate |
| abstract | PROBLEM TO BE SOLVED: To produce a pyruvic acid lower alkyl ester directly from an alkali metal pyruvate in good yield. SOLUTION: A step of neutralizing a mixture of an alkali metal pyruvate, water, a lower alcohol, and 1,2-dichloroethane with a mineral acid, heating the mixture to a temperature of 40 ° C. to the boiling point of the mixture, followed by heating to 30% ° C or less, a step of filtering off crystals in the system, a step of heating below the boiling point of the mixture and removing water in the system by azeotropic dehydration with 1,2-dichloroethane, The lower alkyl pyruvate can be produced from the alkali metal pyruvate in good yield. |
