钌卡宾催化剂在烯烃复分解反应制备α-烯烃中的催化性能研究

Catalytic performance of ruthenium-carbene catalysts for olefin metathesis reaction to synthesisα-olefin

研究了三种钌卡宾催化剂在催化2-辛烯与乙烯复分解反应制备1-庚烯中的应用情况,考察了不同反应温度、压力、催化剂用量对该反应性能的影响。在优化条件下,催化剂2的性能最佳,催化剂活性可达2.0×106g/molRu·h。转化率62.2%,1-庚烯选择性76.5%。

The application of three kinds of ruthenium carbene catalysts in the preparation of 1-heptene by 2-oc- tene and ethylene metathesis reaction was studied. The effect of reactive temperature, reactive pressure and catalyst dosage on reaction were investigated in detail. The result of three catalysts＇ catalytic activity shows that, the cata- lyst 2 has the highest activity. The catalytic activity has up to 2.0× 10^6g/molRu · h. Conversion rate was 62.2%. The selectivity of 1-heptene was 76.5%.
