  • Method for preparing ?,?-unsaturated aldehyde
    Patent number: 10981853
    Abstract: The present invention aims to provide a method for preparing an aldehyde, which can prepare a target aldehyde with high selectivity and can also suppress the production of by-products. The present invention relates to a method for preparing an ?,?-unsaturated aldehyde. The method includes a step of reacting a compound of formula (I) with a compound of formula (II) to provide an ?,?-unsaturated aldehyde of formula (III). An alkali metal hydroxide and an alkanol having 1 to 4 carbon atoms are used in the step. The amount of the alkali metal hydroxide is 8 mol % or more and 12 mol % or less with respect to the compound of formula (I). The total amount of water contained in materials that are used in the reaction is 10 mol % or more and 50 mol % or less with respect to the compound of formula (I).
