    • A process for forming a composition containing over, for example, about 90 % by weight of an alkylene-arylene bridging group-containing bis(diphenyl phosphate) compound and less than, for example, 10 % by weight of monophosphate by-product. This process involves the reaction of a composition containing a diphenyl halophosphate and an alkylene-arylene bridging group-containing diol, in the presence of a catalytic amount of a Lewis acid catalyst, utilizing a means, during the course of the reaction, for removal of hydrohalide by-product. The preferred means that are used for removal of hydrohalide by-product include: utilizing vacuum to remove such by-product; utilizing sparging with an inert gas; utilizing vacuum to remove such by-product in combination with performing the reaction in a hydrocarbon solvent; utilizing sparging with an inert gas in combination with performing the reaction in a hydrocarbon solvent; and utilizing vacuum and sparging with an inert gas in combination with performing the reaction in a hydrocarbon solvent to remove such by-product.
    • 用于形成含有例如约90重量%的含亚烷基 - 亚芳基桥连基的双(二苯基磷酸酯)化合物并且小于例如10重量%的单磷酸酯副产物的组合物的方法。 该方法包括在催化量的路易斯酸催化剂的存在下,含有二苯基卤代磷酸酯和亚烷基 - 亚芳基桥连基团的二醇的组合物的反应,利用在反应过程中除去 氢卤化物副产物。 用于除去氢卤素副产物的优选方法包括:利用真空去除这种副产物; 利用惰性气体喷射; 利用真空除去这种副产物与在烃溶剂中进行反应的组合; 利用惰性气体喷射与在烃溶剂中进行反应的组合; 并与惰性气体一起使用真空和喷射,同时在烃溶剂中进行反应以除去这种副产物。

    • 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。
