Title (EN) A PROCESS FOR 2-OXO-4-METHYLTHIOBUTANOIC ACID OR SALTS THEREOF
(FR) PROCÉDÉ DE PRODUCTION D'ACIDE 2-OXO-4-MÉTHYLTHIOBUTANOÏQUE OU DE SELS DE CELUI-CI
Abstract: front page image
(EN)The present invention provides a novel process for producing 2-oxo-4-methylthiobutanoic acid or salts thereof. A process for producing 2-oxo-4-methylthiobutanoic acid or salts thereof comprises a step of reacting methanethiol metal salts and 2-oxo-3-butenoic acid. Specific example of the methanethiol metal salts includes methanethiol alkali metal salts such as litium methane thiolate, sodium methane thiolate, potassium methane thiolate and the others and methanethiol alkaline-earth metal salts such as calcium methane thiolate, barium methane thiolate and the others.
(FR)Nouveau procédé de production d'acide 2-oxo-4-méthylthiobutanoïque ou de sels de celui-ci, ledit procédé comprenant une étape de réaction des sels métalliques du méthanethiol et d'acide 2-oxo-3-buténoïque. A titre d'exemples spécifiques de sels métalliques du méthanethiol, il y a les sels de métal alcalin du méthanethiol tels que le méthanethiolate de lithium, le méthanethiolate de sodium, le méthanethiolate de potassium et autres, et les sels métalliques alcalinoterreux du méthanethiol tels que le méthanethiolate de calcium, le méthanethiolate de baryum et autres.
