用玻璃外循环反应器研究了MoBiP_(0.1)/SiO_2(克原子比)催化剂上的丁烯-1异构化动力学。在200—300℃之间丁烯-1异构化速度为 丁烯-1异构化活化能为10.9千卡/克分子,丁烯-1吸附热为2.4千卡/克分子。 用吸附指示剂正丁胺滴定法测定了催化剂的酸性,MoBiP_(0.1)/SiO_2催化剂显中等强度酸性。丁烯-1异构成丁烯-2中丁二烯显示强的阻碍作用,而水显示促进作用。在300℃丁二烯对丁烯-1异构化速度的影响用速度方程表示 实验中观察到反应产物中r顺-丁烯-2/r反-丁烯-2比值保持一常数。
The kinetics of the isomerization of butene-1 on a MoBiP_ (0.1) / SiO_2 catalyst was investigated using an external glass loop reactor. The isomerization rate of butene-1 at 200-300 ℃ was 10.9 kcal / mol for butene-1 isomerization and 2.4 kcal / mol for butene-1. The acidity of the catalyst was measured by the n - butylamine titration method, and the moderate acidity of MoBiP_ (0.1) / SiO_2 catalyst was observed. Butadiene-1 isomerization to butadiene in butene-2 shows a strong impeding effect, whereas water shows a promoting effect. The effect of butadiene on the isomerization rate of butene-1 at 300 ° C The rate equation shows that the r-butene-2 / r trans-butene-2 ratio in the reaction product is kept constant.
