Abstract
PURPOSE: To prepare the titled substance, easily, by reacting CO with formaldehyde using an acidic ctalyst such as fluoroantimonic acid, chlorosulfonic acid, pyrosulfuric acid, boron trifluoride, etc., and hydrolyzing the resultant reaction mixture with water.
CONSTITUTION: CO is made to react with formaldehyde or a polymer which produces formaldehyde by depolymerization, in the presence of 0.2W0.0001mol of an acidic catalyst selected from fluoroantimonic acid, chlorosulfonic acid, pyrosulfuric acid, boron trifluoride and fluoroboric acid per 1mol of the formaldehyde component, under a pressure of 20W500kg/cm2 at 80W210°C, and the resultant reaction mixture is hydrolyzed by adding water to obtain glycolic acid.
EFFECT: Since the amount of the catalyst is small, the first step and the second step are carried out successively in the same reactor, and the catalyst can be separated from the reaction product easily.
