PROCESS FOR PRODUCING A PENTAERYTHRITOL ESTER OF 3-MERCAPTOCARBOXYLIC ACID |
摘要 |
A process for producing pentaerythritol mercaptocarboxylic ester by reacting pentaerythritol with a mercaptocarboxylic acid having a content of thioester formed by condensation of two molecules of the acid of 5% or below (in terms of area percentage) as determined by the high-performance liquid chromatography in the case of the total area of the mercaptocarboxylic acid and thioester formed by intermolecular condensation of the acid is taken as 100%. |
