| titleOfInvention | Method for producing phosphonitrile ester |
| abstract | An object of the present invention is to provide a method for efficiently producing a high-purity low-acid-value phosphonitrile ester without causing side reactions such as hydrolysis and crosslinking. SOLUTION: A phosphonitrile ester obtained by reacting a cyclic or linear phosphonitrile dihalide represented by the formula (1) with an alkali metal salt of a compound selected from alcohols, thiols, phenols and thiophenols. Wherein the alkali metal salt is prepared by azeotropically dehydrating a mixture of a hydroxyl or thiol group-containing compound and an alkali metal compound in an organic solvent or without solvent, In the reaction in the organic solvent, the reaction temperature is maintained in a range from the azeotropic temperature of the organic solvent and water to the boiling point of the boiling point of the organic solvent or the boiling point of water, whichever is higher. The reaction temperature is maintained at 40 to 200 ° C., and the water content of the reaction system is maintained at 10% by weight or less of the total weight of the reaction system. [In the formula, n is an integer of 3 or more, and two Xs are the same or different and represent a halogen atom. ] |
