    • A process for isomerization of vinylidene olefins at least in part to tri-substituted ethylene compound which process comprises contacting an olefinic feedstock, containing mostly vinyl olefins and minor amounts of vinylidene olefins, with a catalyst comprising LZ-Y52 zeolite so as to isomerize the vinylidene olefins to the tri-substituted ethylene compounds without losing substantial amounts of the vinyl olefins to side products. A process is preferably applied to a feedstock such as octene-1 containing 2-ethyl-hexane-1 and the 2-ethyl-hexene-1 is isomerized to 3-methyl-heptene-2 and 3-methyl-heptene-3 while retaining all or most all of the octene-1.
    • 至少部分地将亚乙烯基烯烃异构化为三取代的乙烯化合物的方法,该方法包括使含有大部分乙烯基烯烃和少量亚乙烯基烯烃的烯烃原料与包含LZ-Y52沸石的催化剂接触,以使亚乙烯基 烯烃转化成三取代的乙烯化合物,而不会将大量的乙烯基烯烃丢失到副产物中。 一种方法优选应用于含有2-乙基 - 己烷-1的辛烯-1的原料,2-乙基 - 己烯-1异构化为3-甲基 - 庚烯-2和3-甲基 - 庚烯-3,同时保留 全部或大部分的辛烯-1。
