Abstract
A continuous process for producing alkyl and alkoxy alkyl phosphates in which an alkali metal alkoxide at a temperature at 50.degree. C. or less is continuously fed to a reactor while phosphorus oxychloride is continuously fed to the reactor under ratio control. Part of the contents of the reactor is circulated through a cooling device or apparatus to help maintain optimum reaction temperature. The phosphorus oxychloride ratio is adjusted to maintain proper reaction end point. Crude reaction product is continuously removed from the reactor and quenched with water to remove sodium chloride and stop the reaction.
