Title:
3-HYDROXYADIPIC ACID 3,6-LACTONE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/191314
Kind Code:
A1
Abstract:
The present invention makes it possible to produce adipic acid at a high selectivity without emitting dinitrogen monoxide by using a 3-hydroxyadipic acid 3,6-lactone composition as a starting material, the composition containing 3 to 30 parts by weight of α-hydromuconic acid per 100 parts by weight of 3-hydroxyadipic acid 3,6-lactone. The resulting adipic acid can be used as a polyamide starting material or a polyester starting material.
