Title:
METHOD FOR PRODUCING CARBOXYLIC ACID AND ALCOHOL BY HYDROLYSIS OF ESTER
Document Type and Number:
WIPO Patent Application WO/2013/099623
Kind Code:
A1
Abstract:
As represented by formula (1),
(1)
when hydrolysis reaction of methyl laurate was performed by adding methyl laurate (2 mmol) and water (8 ml) to a pyrosulfuric acid ammonium salt catalyst (5 mol%) and heating the mixture to 60°C for 24 hours while stirring, lauric acid was obtained at a yield of 86%.
