Title:
PROCESSES FOR PRODUCTION OF CYCLIC ALKYLENE PHOSPHOHALIDATE AND CYCLIC PHOSPHORIC ACID ESTER
Document Type and Number:
WIPO Patent Application WO/2011/040287
Kind Code:
A1
Abstract:
A process for producing a cyclic alkylene phosphohalidate by reacting a specific alkylene glycol compound with a phosphorus trihalide, wherein the phosphorus trihalide is reacted with the alkylene glycol compound under the conditions where the phosphorus trihalide is present in an excess amount relative to the amount of the alkylene glycol compound in the reaction system; and a process for producing a cyclic phosphoric acid ester using a cyclic alkylene phosphohalidate produced by the aforementioned process as a raw material.
