【発明の名称】ヒドロカルビルビス(ジヒドロカルビルホスフェート)の製造法
Document Type and Number:
Japanese Patent JP2000516587
Kind Code:
A
Abstract:
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: performing the reaction in a hydrocarbon solvent; utilizing vacuum to remove such by-product; utilizing sparging with an inert gas; and compatible combinations of one or more of the foregoing means.
