摘要： A hydroformylation process having improved stability involving reacting one or more reactants, such as an olefin, with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst, to produce a reaction product fluid comprising one or more products, preferably aldehydes; wherein said process is conducted in a region of the hydroformylation rate curve that is negative or inverse order in carbon monoxide; and wherein total pressure is controlled at a predetermined target value and/or vent flow rate is controlled at a predetermined target value, by adjusting a flow of a carbon-monoxide containing inlet gas, so as to prevent sudden changes and/or lessen cycling of process parameters, for example, reaction rate, total pressure, vent flow rate, temperature, or a combination thereof.
摘要翻译：加氢甲酰化方法具有改进的稳定性，包括在加氢甲酰化催化剂存在下使一种或多种反应物（例如烯烃）与一氧化碳和氢反应，以产生包含一种或多种产物，优选醛的反应产物流体; 其中所述方法在加氢甲酰化速率曲线的一个区域中进行，所述加氢甲酰化速率曲线在一氧化碳中是负的或反向的; 并且其中通过调节含一氧化碳的入口气体的流量将总压力控制在预定目标值和/或排放流量被控制在预定目标值，以防止突然变化和/或减少循环工艺参数，例如反应速率，总压力，通风流量，温度或其组合。

摘要： A cross-metathesis process for preparing an a, ?-functionalized olefin, such as methyl 9-decenoate, and an a-olefin having three or more carbon atoms, such as 1-decene. The process involves contacting in a first reaction zone an a-functionalized internal olefin, such as methyl oleate, and an a-olefinic monomer having three or more carbon atoms, such as 1-decene, with a first metathesis catalyst to prepare an effluent stream containing the a, ?-functionalized olefin, such as methyl 9-decenoate, an unfunctionalized internal olefin, such as 9-octadecene, unconverted reactant olefins, and optionally, an a, ?-difunctionalized internal olefinic dimer, such as dimethyl 9-octadecen-1,18-dioate; separating said effluent streams; then contacting in a second reaction zone the unfunctionalized internal olefin with ethylene in the presence of a second metathesis catalyst to obtain a second product effluent containing the a-olefinic monomer having three or more carbon atoms; and cycling a portion of the a-olefinic monomer stream(s) to the first reaction zone.
