<p>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 (R˄O˄)P , 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.</p> |
