WIPO Patent Application WO/2015/012550

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing methylol alkanal. According to the present invention, the method can improve the yield of methylol alkanal without using an excess amount of formaldehyde greater than or equal to a theoretical minimum molar ratio, reduce formaldehyde wastewater, and resultingly improve the efficiency of hydrogenation due to the decrease in the remaining formaldehyde amount contained in the methylol alkanal, which can act as catalytic poison of hydrogenation when the prepared methylol alkanal is applied to hydrogenation.
