摘要：
The invention relates to a method for hydroformylation of unsaturated compounds such as olefins and alkynes using mixtures of synthesis gas (CO/H
2 ), in which either the unsaturated compounds and a catalyst are heated to a reaction temperature of 60 to 200°C and the synthesis gas is then introduced, or the unsaturated compounds and the catalyst are brought into contact with pure CO at normal temperature in a preformation step, then are heated to reaction temperature and on reaching the reaction temperature the CO is replaced by the synthesis gas. The pressure is 1 to 200 bar and the CO:H
2 ratio in the synthesis gas is in the range from 1:1 to 50:1. The iridium catalyst used comprises a phosphorus-containing ligand in an iridium:ligand ratio in the range from 1:1 to 1:100. With high catalyst activities and low catalyst use, very high turnover frequencies are achieved.

本发明涉及使用合成气（CO / H 2）的混合物将不饱和化合物如烯烃和炔烃加氢甲酰化的方法，其中将不饱和化合物和催化剂加热至60-200℃的反应温度， 然后加入合成气，或者将不饱和化合物和催化剂在预成型步骤中在常温下与纯的CO接触，然后加热至反应温度，达到反应温度后，CO被合成气代替。 压力为1〜200巴，合成气中的CO:H 2比在1：1〜50：1的范围内。 所用的铱催化剂包括铱：配体比例为1:1至1:100的含磷配体。 具有高催化剂活性和低催化剂用途，实现了非常高的周转频率。
