| abstract | The subject of the present invention is a process for producing polyoxyalkylene glycol by copolymerization of THF and neopentyl glycol in the presence of a heteropolyacid in the one-step production method of general formula (I) in neopentyl glycol (wherein R 3 When R 1 is an oxyformyl group or an isopropionate group, R 1 and R 2 represent hydrogen, and when R 3 represents an isopropyl group, R 1 represents hydrogen and R 2 represents hydroxy, and R 2 and -OCH 2 -C R 3 together (CH 3) -CH 2 - polyoxyalkylene the total amount of all impurities in the R 1 represents hydrogen) in the case of a group is equal to or less than 1000ppm This is a one-step process for producing glycol. |
