ABSTRACT:
Phosphorous acid diesters may be prepared by the reaction of an alkoxylated alkyl phenol with a phosphorus trihalide, or, in combination with water, with a triaryl phosphite. The former reaction also produces, as a byproduct, the corresponding halide. The resulting phosphorus-containing compositions are useful as additives for metal working lubricants.
