Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with anhydrous hydrogen fluoride in an inert solvent in a manner such that said anhydrous hydrogen fluoride is added to said phosphorus compound at a rate such that said anhydrous hydrogen fluoride reacts with said phosphorus compound without the accumulation of an amount of unreacted anhydrous hydrogen fluoride which is sufficient to cause substantial decomposition of the desired fluorophosphorus product.
至少有一个氯、溴或碘直接与磷键合的磷化合物,通过在惰性溶剂中与无水氟化氢反应,用氟进行反卤化,反应的方式是将所述无水氟化氢加入到所述磷化合物中,加入的速度使所述无水氟化氢与所述磷化合物反应,而不会积累一定量的未反应的无水氟化氢,足以导致所需的氟磷产品的大量分解。
