Method of carboxylic acids isomerization |
| abstract |
FIELD: organic chemistry. SUBSTANCE: invention relates to a method of isomerization of the branched carboxylic acids, to a process of isomerization of at least a single saturated branched carboxylic acid at heating. Process is carried out in the presence of effective amount of iridium catalyst and iodine or bromine promoter at molar ratio promoter/Ir = 0.1/1-20/1. Method ensures to increase value of methylglutaric and ethylsuccinic acids due to their conversion to adipic acid. EFFECT: improved method of isomerization. 14 cl, 16 ex |
