    • (1) Osmium tetraoxide carried on a polyolefin having an ion-exchange group such as a primary amino group, -NHR, -NRR', -NR'R (wherein R, R' and R" independently represent each alkyl, aryl or aralkyl) or sulfonate group bonded thereto; supports for carrying osmium tetraoxide which contain a polyolefin having the above-described ion-exchange group bonded thereto; and oxidation catalysts comprising osmium tetraoxide carried on such a support; (2) a process for producing a carried osmium tetraoxide by bringing such a support with osmium tetraoxide; (3) a method of storing osmium tetraoxide by carrying osmium tetraoxide on such a support; and (4) a process for producing a diol compound by treating an olefin with an oxidation catalyst comprising the carried osmium tetraoxide as described above. According to the above method, an osmium-carrying compound which can be easily handled, has an excellent solvent resistance and suffers from no decrease in the catalytic activity even after repeated use can be industrially produced.
    • (1)负载在具有伯氨基,-NHR,-NRR',-NR'R“的离子交换基团的聚烯烃上的四氧化锇(其中R,R'和R”各自独立地表示 烷基,芳基或芳烷基)或磺酸盐基团;用于携带含有上述离子交换基团的聚烯烃的四氧化锇的载体;以及包含在这种载体上承载的四氧化锇的氧化催化剂;(2) 通过将这种载体用四氧化锇来制造载体的四氧化锇;(3)通过在这种载体上载持四氧化锇来储存四氧化锇的方法;以及(4)通过用烯烃处理生产二醇化合物的方法, 包含上述携带的四氧化锇的氧化催化剂根据上述方法,可以容易地处理的携带锇的化合物具有优异的耐溶剂性,即使在重复后也不会降低催化活性 用途可以在工业上生产。
