    Abstract: Sorbic acid is prepared by splitting the ketene/crotonic aldehyde polyester in the presence of a macro-reticulated exchange resin having a pore diameter of at least 200 A on the average and a water content of less than 20 percent by weight. The process can be carried out discontinuously or continuously with a good yield, the sorbic acid obtained having a high quality.

    Abstract translation: 通过在孔径为至少200A的大网状交换树脂的存在下平均分解乙烯酮/巴豆醛聚酯并且水含量小于20重量%来制备山梨酸。 该方法可以不间断地或连续地以良好的产率进行,获得的山梨酸具有高质量。
