Synthesis of methoxypoly(oxyethylene)propionic acid
We have investigated the reaction chemistry of methoxypoly(oxyethylene)propionitrile, I, to synthesize methoxypoly(oxyethylene)propionic acid, II. We have found that II can be prepared by converting I first to the corresponding amide. Subsequent hydrolysis of the amide then yields II.
