    • A process for the synthesis of a hydrocarbyl bis(dihydrocarbyl phosphate), such as a hydrocarbyl bis(diaryl phosphate), comprises the reaction of an unstable hydrocarbyl-containing diol, such as an aromatic group-containing diol, with a dihydrocarbyl halophosphate, such as diphenyl chlorophosphate, in the presence of a Lewis acid catalyst, such as magnesium dichloride, in the additional presence of an effective amount (e.g., up to about 100 % by weight of diol and halophosphate) of a liquid hydrocarbon, such as an aliphatic hydrocarbon, like heptane, or an aromatic hydrocarbon, such as toluene, to enhance the removal of hydrogen halide by-product and thereby increase the yield of hydrocarbyl bis(dihydrocarbyl phosphate).
    • 合成烃基双(二烃基磷酸酯)例如烃基双(二芳基磷酸酯)的方法包括使不稳定的含烃基二醇如含芳族基团的二醇与卤代磷酸二烃基酯反应,例如 作为氯代磷酸二苯酯,在路易斯酸催化剂例如二氯化镁的存在下,在另外存在有效量(例如至多约100重量%的二醇和卤代磷酸盐)的液态烃例如脂族 烃如庚烷或芳烃如甲苯,以增强卤化氢副产物的除去,从而提高烃基双(二烃基磷酸酯)的产率。
