Abstract
A process for the preparation of trialkyl and trialkenyl phosphates. The process involves oxidation of the corresponding phosphite with oxygen or an oxygen-containing gas. The oxidation is catalyzed by a metal catalyst such as a transition metal carboxylate, for example, and is carried out at relatively low temperatures.
Claims7
