Title:
METHOD FOR PRODUCING α,β-UNSATURATED ALDEHYDE
Document Type and Number:
WIPO Patent Application WO/2019/116608
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing an aldehyde, wherein a desired aldehyde can be obtained with a high selectivity and the formation of byproducts can be suppressed. The present invention pertains to a method for producing an α,β-unsaturated aldehyde, the method comprising a step for reacting a compound of formula (I) with a compound of formula (II) to obtain an α,β-unsaturated aldehyde of formula (III), wherein in said step, an alkali metal hydroxide and a C1-4 alkanol are used, the amount of the alkali metal hydroxide is 8-12 mol% with respect to the compound of formula (I), and the total amount of water contained in the raw materials used in the reaction is 10-15 mol% with respect to the compound of formula (I).
