    摘要: Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are trans­halogenated with fluorine by reaction with a fluoride salt, e.g., KF or ammonium fluoride, in the presence of a hydrogen halide salt of a pyridine-type nitrogen base, e.g., pyridine hydrochloride.

    摘要: A process for preparation of phosphoric esters which comprises step (1) of reacting phosphorus oxychloride with naphthol at a molar ratio of not larger than 1/1.3 in the presence of a metal halide and removing unreacted phosphorus oxychloride and step (2) of reacting the reaction product of step (1) with phenol at a molar ratio (of chlorine contained in the reaction product to phenol) ranging from 1 : 1 to 1 : 1.5 and removing hydrogen chloride formed by a by-product to thereby obtain a phosphoric ester represented by the general formula (I): (1) wherein n is 1 or 2.
