Abstract
High quality trimethylolalkane can be easily and efficiently produced at a high yield through a reaction between n-alkanal and formaldehyde in the presence of tertiary amine and water, in which a reaction mixture obtained aster the reaction is heated so that a salt of tertiary amine with formic acid produced as a by-product is decomposed into hydrogen and carbon dioxide and/or water and carbon monoxide, and tertiary amine; and the tertiary amine distilled from the reaction mixture is reused in producing trimethylolalkane.
