    • A process for the hydroformylation of alpha-olefins employing a rhodium catalyst complexed with carbon monoxide and a triarylphosphine wherein the intrinsic deactivation of the rhodium catalyst which occurs under hydroformylation conditions is inhibited or substantially prevented by determining and correlating the reaction conditions of temperature, carbon monoxide partial pressure and the free triarylphosphine: catalytically-active rhodium metal mole ratio. These conditions can be determined from a mathematical relationship between the combination of these variables and the stability of the rhodium complex catalyst.
    • 使用与一氧化碳和三芳基膦络合的铑催化剂进行α-烯烃加氢甲酰化的方法,其中在加氢甲酰化条件下发生的铑催化剂的固有失活被抑制或基本上通过确定和相关的温度,一氧化碳 分压和游离三芳基膦:催化活性铑金属摩尔比。 这些条件可以根据这些变量的组合与铑配合物催化剂的稳定性之间的数学关系来确定。

    • An improved hydroformylation process 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, which is sufficient to prevent and/or lessen deactivation of the hydroformylation catalyst; 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 and/or lessen cycling of process parameters, e.g., reaction rate, total pressure, vent flow rate, and/or temperature.
    • 改进的加氢甲酰化方法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相的,这足以防止和/或减少加氢甲酰化催化剂的失活; 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/或排气流量被控制在预定目标值,以便防止和/或减少工艺参数的循环 ,例如反应速率,总压力,排气流速和/或温度。
