摘要
丙烯氢甲酰化过程(以下简称氢甲酰化过程),可以用如下反应式表示: 作者在进行氢甲酰化动力学研究中发现,在接近工业生产条件,特别是使用了适当聚合度的正丁醛做溶剂时,只要控制一定的操作条件,即可在反应的母体转化期和诱导期内检测出反应体系的气相中各组分浓度的振荡变化。
A propylene hydroformylation system in presence of the rhodium-phosphine catalyst has been monitored with a gas-liquid chromatograph. It has been proved that the system is a chemical oscillation system in certain conditions. The experiment has shown that the oscillation of this system requests[CH]/[H+CO]>1 in gas phase. The action of the solvent is quite special, i.e.a suitable quantity of tripolymer of n-butyladehyde has to exist. The hydroformylation reaction will not go on if the content of the tripolymer is too high, and the oscillation phenomenon will not occur if its content is too low. Since until now there are no reports about the effect of butyladehyde properties on this catalytic reaction and about the concentration oscillation phenomenon of the rhodium-phosphine catalyst system, the progressive study of this system will be ver yinteresting.
