    • A process for preparing halogen-substituted aryl phosphonates represented by formula (I): wherein each Hal independently represents halogen; k is 1 or 2; n is an integer between 1 and 5, inclusive; m is an integer between 1 and 3, inclusive; and R is a straight or branched C1-C5 alkyl group which may be optionally substituted with one or more halogen atoms, which process comprises reacting under heating a compound represented by the following formula: wherein X is a leaving group, with trialkyl phosphite of the formula (RO)3P, wherein the product of Formula I is produced and maintained in a liquid form and functions as an indigenous reaction liquid medium for suspending or dissolving the reactants, wherein the temperature of the reaction mixture is not less than the melting temperature of said compound of Formula I during at least a portion of the reaction time, and recovering the product of Formula I in a liquid form.
    • 由式(I)表示的卤素取代的芳基膦酸酯的制备方法:其中每个Hal独立地表示卤素; k为1或2; n是1和5之间的整数,包括1和5; m是1和3之间的整数,包括1和3; 并且R是可以任选被一个或多个卤素原子取代的直链或支链C 1 -C 5烷基,该方法包括在加热下使由下式表示的化合物:其中X是离去基团,与 式(RO)3P,其中式I的产物被制备并保持为液体形式,并用作悬浮或溶解反应物的本地反应液体介质,其中反应混合物的温度不低于 所述式I的化合物在至少一部分反应时间内,并以液体形式回收式I的产物。
