报道用未经分离的３０万吨／年乙烯副产Ｃ＿５馏份制混合己醇的研究，研制了一种加氢性能强、稳定性好的钴－膦配合物催化剂；考察了膦钴比的影响、碱性助催化剂的作用、反应的工艺条件等。试验表明，在反应温度１８０℃、压力６．０－７．０ＭＰａ、Ｈ＿２：ＣＯ＝２．５（摩尔比）、时间７小时的条件下，脂肪醇收率可达９９．０％（以Ｃ＿５烯为基准）。将试验所得产品用作ＰＶＣ的增塑剂原料，表明由羰化混合己醇制备的邻苯二甲酸二己脂增塑剂可以用于合成人造革的生产，其各项应用指标达到部颁标准。
Reported the unseparated 300,000 tons / year of ethylene by-product C_5 fraction mixed hexanol study developed a strong hydrogenation performance, good stability of the cobalt-phosphine complex catalyst; investigated the ratio of phosphine and cobalt Influence, the role of alkaline promoters, the reaction conditions and so on. The results show that the yield of fatty alcohol can reach 99.0% under the conditions of reaction temperature of 180 ℃, pressure of 6.0-7.0MPa, H_2: CO = 2.5 (molar ratio) and time of 7 hours Alkene). The product obtained from the test was used as a raw material for plasticizer of PVC, indicating that the dihexyl phthalate plasticizer prepared by carbonylation mixed with hexanol can be used for the production of synthetic leather, and its application indexes have met the ministry standard.
