本文首次报道在液相中，用金属酞菁催化氧化脱除羰基硫(COS)。发现COS先被水解成HS~－，HS~-再被氧化成S，酞菁钴(CoPC)的活性高于其它金属酞菁(MPC)，酞菁苯环上推电子基因使酞菁的催化活性提高，双核酞菁钴的活性高子单核酞菁钴。D296树脂负载的酞菁钴的催化活性高于均相酞菁钴的活性。
Abstract：This paper first reported that the carbonyl sulfide (COS) was removed by metallophthalocyanine catalytic oxidation in solution. It discovered that COS hydrolyzed to HS-, then which was oxidated to S. The cobalt(Ⅱ) phthalocyaninehas the highest catalytic activity than other metallophthalocyanme. The pushingelectron groups on phthalocyanine benzenoid increased its catalytic activity. The activity of binuclear cobalt(Ⅱ) phthalocyanine is higher than that of cobalt(Ⅱ ) phthalocyanine. The activity cobalt(Ⅱ ) phthalocyanine supported on D296 is higherthan that of cobalt(Ⅱ ) phthalocyanine in homogeneous phase.
