    • A vegetable oil-based polyol is made by adding a peroxyacid to vegetable oil wherein said peroxyacid reacts with said vegetable oil to form epoxidized vegetable oil and adding said epoxidized vegetable oil to a mixture of an alcohol, water, and a catalytic amount of fluoboric acid so as to form a vegetable oil-based polyol. A further embodiment of the present invention involves making a vegetable oil-based polyol using an epoxidized vegetable oil as the starting material. The epoxidized vegetable oil undergoes hydroxylation by the same process as outlined above. According to another aspect of the present invention, the vegetable oil-based polyol formed by the novel methods of this invention may be reacted with an isocyanate to form a polyurethane. Alternatively, a filler such as silica may be combined with the vegetable oil-based polyol before it is reacted with the isocyanate. These polyurethanes made from vegetable oil-based polyols may be used to form electroinsulating casting resins.
    • 通过向植物油中加入过氧酸而制备植物油性多元醇,其中所述过氧酸与所述植物油反应形成环氧化植物油,并将所述环氧化植物油加入到醇,水和催化量的氟硼酸的混合物中 以形成植物油基多元醇。 本发明的另一个实施方案涉及使用环氧化植物油作为原料制备植物油基多元醇。 环氧化植物油通过与上述相同的方法进行羟基化。 根据本发明的另一方面,通过本发明的新方法形成的植物油基多元醇可以与异氰酸酯反应形成聚氨酯。 或者,诸如二氧化硅的填料可以在与异氰酸酯反应之前与植物油基多元醇组合。 这些由植物油基多元醇制成的聚氨酯可用于形成电绝缘铸塑树脂。

    • A method for making natural oil-based polyols directly from vegetable or animal oil using a consecutive two-step process involving epoxidation and hydroxylation is provided. Specifically, this process comprises adding a peroxyacid to a natural oil wherein said natural oil and said peroxyacid react to form an epoxidized natural oil and adding said epoxidized natural oil to a mixture of an alcohol, water, and a fluoboric acid catalyst. The catalytic amount of fluoboric acid is less than about 0.5% by weight of the entire reaction mixture, and the amount of water is about 10 to 30% by weight of the entire mixture. The epoxidized natural oil undergoes hydroxylation and forms a natural oil-based polyol. The present invention further includes a method for making natural oil-based polyols from epoxidized oil by hydroylating the epoxidized oil in the presence of fluoboric acid, alcohol and water in the amounts discussed above. The natural oil-based polyols created by this method may be reacted with isocyanates so as to form polyurethanes, which is another embodiment of the present invention. Alternatively, fillers such as silica may be combined with these natural oil-based polyols before they are reacted with isocyanates to form polyurethanes. In still another embodiment of the present invention, polyurethanes made from natural oil-based polyols may be used to form electroinsulating casting resins for use in electrical applications.
    • 提供了一种使用直接由植物油或动物油直接制备天然油基多元醇的方法,该方法使用涉及环氧化和羟基化的连续两步法。 具体地,该方法包括向天然油中加入过氧酸,其中所述天然油和所述过氧酸反应形成环氧化天然油,并将所述环氧化天然油加入到醇,水和氟硼酸催化剂的混合物中。 氟硼酸的催化量小于整个反应混合物的约0.5重量%,水的量为整个混合物的约10至30重量%。 环氧化天然油经历羟基化,形成天然油基多元醇。 本发明还包括通过在上述量的氟硼酸,醇和水的存在下对环氧化油进行水解来制备环氧化油的天然油基多元醇的方法。通过该方法制备的天然油基多元醇可以是 与异氰酸酯反应以形成聚氨酯,这是本发明的另一个实施方案。 或者,诸如二氧化硅的填料可以在与异氰酸酯反应形成聚氨酯之前与这些天然油基多元醇组合。 在本发明的另一个实施方案中,由天然油基多元醇制成的聚氨酯可用于形成用于电气应用的电绝缘铸塑树脂。
