Method for preparing phosphite diester by transesterification

The invention discloses a method for preparing phosphite diester by transesterification. Dimethyl phosphite and monohydric alcohol which are used as raw materials are stirred, reacted and rectified under the action of a basic catalyst to prepare the phosphite diester, so the problems of high deice requirements and large amount of acid-containing three wastes in the process of producing the phosphite diester by reacting phosphorus trichloride with alcohol are avoided. The method has the advantages of low raw material toxicity, simple process, mild reaction conditions, low device requirements, low pollution, high raw material conversion rate, high product selectivity, stable supply of the raw materials, provision of the phosphite diester used for fine chemical engineering or medical intermediates by dimethyl phosphite production enterprises, high added values of the product, and provision of a new way for the synthesis of the phosphite diester.

A convenient two-step synthesis of dialkylphosphate ionic liquids

Dialkylphosphate ionic liquids are useful solvents for cellulose dissolution and catalytic reactions. In this paper, a new methodology for the synthesis of hydrophobic phosphate-based ionic liquids is described. This method involves the oxidation reaction of an easily prepared H-phosphonate precursor by using the environmentally friendly and inexpensive oxidizing agent hydrogen peroxide.
