通过红外光谱研究了 233 至 253K 范围内镁碱沸石 (FER) 小孔中存在的酸性 OH 基团吸附正丁烯的动力学。 1-丁烯和顺式2-丁烯的吸附活化能估计为23.3和28.4kJmol−1，而反式2-丁烯由于其快速吸附而没有获得吸附活化能。吸附活化能被认为是由正丁烯分子扩散到 FER 的小微孔中产生的。
Kinetics on the adsorption of n-butene onto the acidic OH groups existing in the small pores of ferrierite (FER) were studied between 233 and 253K by IR spectroscopy. The activation energies for the adsorption of 1-butene and cis-2-butene were estimated as 23.3 and 28.4kJmol−1, while that of trans-2-butene was not obtained due to its rapid adsorption. The activation energy for adsorption was considered to have resulted from the diffusion of n-butene molecules into the small micropores of FER.
