PROCESSES FOR PRODUCTION OF CYCLIC ALKYLENE PHOSPHOROHALIDATE AND CYCLIC PHOSPHORIC ACID ESTER

摘要

A process for producing a cyclic alkylene phosphorohalidite, which comprises reacting a specific phosphorus trihalide with a specific alkylene glycol compound under conditions where the phosphorus trihalide is present in an excess amount relative to the amount of the alkylene glycol compound in the reaction system to order to obtain the cyclic alkylene phosphorohalidite by reacting the alkylene glycol compound with the phosphorus trihalide; and a process for producing a cyclic phosphoric acid ester by using the obtained cyclic alkylene phosphorohalidite as a raw material.
