WIPO Patent Application WO/2014/073663

Kind Code:

A1

Abstract:

This method for purifying an aldehyde compound comprises: a step for neutralizing a reaction solution, which contains an aldehyde compound that is obtained by reacting a compound represented by general formula (a1) or (a2) with hydrogen and carbon monoxide in the presence of a group 8-10 metal compound and a phosphorus compound, by adding water and a basic compound into the reaction solution; and a step for distilling the neutralized reaction solution. The phosphorus compound is represented by formula (R1O)3P, and the basic compound is at least one salt that is selected from among carbonates and hydrogen carbonates of group I metals of the periodic table and carbonates and hydrogen carbonates of group II metals of the periodic table.
