  公开（公告）日：1981-05-27

  A process for producing ethanol from the reaction of methanol, hydrogen and carbon monoxide catalyzed by a phosphine-iodine promoted cobaltruthenium catalyst, the improvement of maintaining the phosphine to halide ratio and concentration within a critical range, and whereby the concentration of phosphine compound in the reaction mixture is increased without causing an undesirable decrease in the activity of the catalyst; thereby obtaining a highly stable and active catalyst providing an increased selectivity to ethanol formation. This is accomplished under such conditions that the catalyst stability is maintained and the ratio of phosphine to halide is kept at a relatively constant value during the reaction.

  一种利用膦碘促进钴钌催化剂催化甲醇、氢气和一氧化碳反应制取乙醇的工艺，其改进之处在于将膦与卤化物的比例和浓度保持在临界范围内，并在不引起催化剂活性下降的情况下提高反应混合物中膦化合物的浓度；从而获得一种高度稳定和活性的催化剂，提高乙醇生成的选择性。这是在这样的条件下实现的，即在反应过程中保持催化剂的稳定性，膦与卤化物的比例保持在一个相对恒定的值。
• Selective homologation of acetals or ethers to monohydric or polyhydric alcohols

  公开（公告）日：1981-08-26

  A catalyst system comprising cobalt, ruthenium, an iodine promoter and an organic phosphine ligand effectively catalyzes the reaction of acetals or ethers with syn gas to produce alcohols, glycols and/or glycol ethers as well as the subsequent reaction of such products with syn gas to produce monohydric or dihydric alcohols. The process achieves higher than heretofore achieved selectivity to desired products while maintaining catalyst stability. The homologation reaction can be carried out with or without an inert nonpolar cosolvent.

  一种由钴、钌、碘促进剂和有机膦配体组成的催化剂体系可有效催化乙醛或乙醚与合成气的反应，生成醇、乙二醇和/或乙二醇醚，以及这些产物与合成气的后续反应，生成一元醇或二元醇。该工艺在保持催化剂稳定性的同时，对所需产品的选择性比以前更高。该均化反应可在使用或不使用惰性非极性助溶剂的情况下进行。
• Catalyst and process for the conversion of methanol to acetaldehyde

  公开号：EP0068499A1

  公开（公告）日：1983-01-05

  A catalyst mixture is made with improved activity and selectivity to acetaldehyde by using an inert diluent and specifically defined concentrations of cobalt, a halide, a trivalent phosphorus compound, and the inert diluent. Use of the trivalent phosphorus compound significantly inhibits corrosion of the reactor metal.

  通过使用惰性稀释剂和特定浓度的钴、卤化物、三价磷化合物和惰性稀释剂，可制成活性和乙醛选择性均得到改善的催化剂混合物。使用三价磷化合物可显著抑制反应器金属的腐蚀。
