    • The invention provides an improved method of synthesizing chemicals according to the ene reaction. The method addresses two problems that previously could not be addressed simultaneously, preventing charring of the reaction, and preventing gaseous degradation of the reagents. The method involves adding a boron bearing compound and an aromatic/antioxidant compound to the ene reaction. Combining these two compounds together inhibits charring and also causes an effect that neither compound can accomplish alone. The addition of these two compounds together also more effectively prevents either of the reagents from degrading than when either reagent is added alone. As a result the method reduces costs by reducing the amount of reagents needed for a synthesis and further reduces costs by eliminating the need to filter out char from the end products of the ene reaction. The method is particularly useful in the ene reaction synthesis of ASA from olefins and maleic anhydride.
    • 本发明提供了根据烯类反应合成化学品的改进方法。 该方法解决了以前不能同时解决的两个问题,防止反应发生炭化,并防止试剂的气体降解。 该方法包括将硼载体化合物和芳族/抗氧化剂化合物加入到烯类反应中。 将这两种化合物结合在一起抑制炭化,并且还引起两种化合物都可以单独实现的效果。 当两种化合物一起添加时,与单独添加任一种试剂相比,更有效地防止任一试剂降解。 因此,该方法通过减少合成所需的试剂的量来降低成本,并且通过不需要从烯酯反应的最终产物中过滤掉炭而进一步降低成本。 该方法特别可用于烯烃和马来酸酐的烯醇反应合成ASA。
