Title:
METHOD FOR PRODUCING ALDOL CONDENSATION PRODUCT FROM ALDEHYDE
Document Type and Number:
WIPO Patent Application WO/2020/022114
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for efficiently producing an aldol condensation product from an aldehyde. The present invention includes a method for producing an aldol condensation product, which utilizes an aldol condensation reaction of an aldehyde, and which comprises a step wherein an aldehyde in a gaseous state and at least one catalyst selected from among silica, alumina and silica-alumina are brought into contact with each other. It is preferable that the catalyst has a BET specific surface area of from 220 m2g-1 to 380 m2g-1.
