- - 1 MIXTURES OF ITACONIC ACID OR ITACONIC ACID DERIVATIVES AND PRIMARY AMINES FOR PRODUCING 13- AND 14-ALKYL METHYL PYRROLIDONES

摘要

The present invention is a primary amine for itaconic acid or itaconic acid in a molar ratio of derivatives 0.5 of the formula I: 1 to 20: Chemical formula of 50 mol% or less relative to a first range, an itaconic acid or itaconic acid derivatives used used II of 4-carboxy-pyrrolidone, class 1, characterized in that the 4-carboxy-4-carboxylic pyrrolidone derivatives and contains bami fled Raleigh money of formula III of the money of the formula II, itaconic or itaconic acid derivatives and the general formula (I) It relates to a mixture containing the amine. Formula I Formula II Formula III Wherein, R is a saturated aliphatic group having a linear or branched saturated aliphatic group, or a 3 to 24 carbon atoms having 1 to 24 carbon atoms. The invention also use in the production of the mixtures according to the invention, 1, 3-alkyl-methylpyrrolidone and / or a 1,4-alkyl-methylpyrrolidone, and 1, 3-alkyl-methylpyrrolidone and / 1,4-alkyl or a method of producing methyl pyrrolidone. The present invention is also 1, 3-alkyl-methylpyrrolidone fraction of the range of 10 to 10,000 ppm of Aberdeen, 1, 3-alkyl-methylpyrrolidone and / or 1,4- and 1,3-alkyl-methylpyrrolidone mixture containing the alkyl-methylpyrrolidine, and 1, 3-alkyl-methylpyrrolidone, 1,4-alkyl-methylpyrrolidone for a molar ratio of money from 1: 1 to 10: 1, characterized in that the range of 1,3 alkyl-methylpyrrolidone and 1,4-alkyl relates to a mixture containing methyl pyrrolidone.
