Title:
SOLID-SUPPORTED METALLOPORPHYRIN CATALYST AND APPLICATION THEREOF IN PREPARATION OF MALEIC ACID
Document Type and Number:
WIPO Patent Application WO/2018/171251
Kind Code:
A1
Abstract:
The invention discloses a solid-supported metalloporphyrin catalyst and an application thereof in the preparation of maleic acid. The solid-supported metalloporphyrin catalyst is used for preparing maleic acid by catalyzing furfural and has a good catalytic effect, and reaction conditions are mild, so that the required energy consumption is reduced compared to the prior art. The invention increases the yield and selectivity of maleic acid, the conversion rate of furfural is 20.4%-95.6%, the yield of maleic acid is 10%-56.1%, and the selectivity of maleic acid is 43.6%-76.1%. At the same time, the catalyst is easy to separate, can be recycled and reused multiple times and is environmentally-friendly.
