Abstract
A process for the production of alkoxyalkyl triorganic phosphates utilizing a continuous process for the manufacture of alkoxyalkyl alkoxides comprising treating an alkoxyalkanol with a sodium borohydride for 20 minutes to 4 hours reacting the treated alkoxyalkanol continuously with an alkali metal hydroxide to form an alkali metal alkoxide. A large excess of alcohol is employed. The alkoxide is phosphorylated to form a trialkoxyalkyl phosphate. The alkoxidation reaction and the phosphorylation reaction are both conducted in a non-oxidizing atmosphere. The crude product is then refined by conventional means.
