  A supported titanium catalyst component for use in propylene polymerization is prepared by copulverizing a mixture of magnesium dichloride, titanium tetrachloride- ethylbenzoate 1: 1 adduct and hexachloroethane for 20 to 44 hrs., and then treating the resulting titanium-containing solid with n-heptane solution of hexachloroethane. Bulk polymerization of propylene in the presence of H2 with the catalyst composed of the supported titanium catalyst component and the organo aluminum catalyst component composed of triisobutyl aluminum and ethylbenzoate at 68°C. for half an hour gives higher catalyst efficiency (above 200,000 g PP/g-Ti) and sufficient heptane insolubles (92 to 97%).

  将二氯化镁、四氯化钛-苯甲酸乙酯 1:1 加合物和六氯乙烷的混合物共混 20 至 44 小时，然后用六氯乙烷的正庚烷溶液处理所得到的含钛固体，制备出用于丙烯聚合的支撑钛催化剂组分。在有 H2 存在的情况下，使用由支撑钛催化剂组分和由三异丁基铝和苯甲酸乙酯组成的有机铝催化剂组分组成的催化剂，在 68℃下半小时进行丙烯的批量聚合，可获得较高的催化剂效率（超过 200,000 克 PP/克-钛）和足够的庚烷不溶物（92%至 97%）。

  A supported titanium catalyst component is produced by cogrinding an organo aluminum catalyst component with a supported titanium (IV) halide on a magnesium halide. The resulting supported titanium halide catalyst component, when employed with an organo aluminum catalyst component to form a catalyst system is highly useful for the stereoregular polymerization of α-olefins as well as the copolymerization of α-olefins.

  A supported titanium catalyst component, suitable for use in the polymerization of alph-olefins, is produced by treating a supported titanium-containing solid obtained by co-pulverization of a magnesium halide, a tetravalent titanium halide which may also comprise an electron donor compound and/or a halogen compound with an organohalogen compound. The component is thereafter treated with an organoaluminum compound and an electron donor compound. The resulting supported titanium catalyst, when employed as a titanium component with an organoaluminum catalyst componet results on a catalyst system useful for the polymerization of alpha-olefins.

  通过将卤化镁、四价卤化钛（其中可能还包括一种电子供体化合物和/或一种卤素化合物）与一种有机卤素化合物共同粉碎而得到的一种含钛固体进行处理，从而制得一种适用于烷基烯烃聚合的支撑钛催化剂组分。然后用有机铝化合物和电子供体化合物处理该组分。这样得到的支撑钛催化剂，在作为钛组分与有机铝催化剂组分一起使用时，就形成了一种可用于α-烯烃聚合的催化剂体系。

  A supported titanium containing catalyst component for use in propylene polymerization is prepared by co-pulverizing a magnesium haiide, an aromatic carboxylic acid ester and an aromatic carboxylic acid or a derivative thereof such the halide or anhydride and contacting the magnesium-containing solid with a titanium compound. The polymerization of propylene in the presence of a catalyst comprising this component and an organoaluminum compound produces polypropylene of high bulk density.

  Racemic carboxylic acids are resolved into their enantiomers using optically active enantiomers of four lactones as resolving agents. The four lactones are 2,3-isopropylidene-ribonic acid-1,4-lactone; 1,2-isopropylidene-. glucofuranurono-3,6-lactone; 2-hydroxy-3,3-dimethyi-1,4- butyrolactone and 3,4-isopropylidene-arabino-1,5-lactone. Novel diastereoisomeric esters of the acids with the lactones are disclosed.
