Abstract

성질이 서로 다른 두 그물구조상 수지촉매, Amberlyst 15와 Amberlyst XN-1010을 이용하여 에틸렌 및 프로필렌과 벤젠의 기상 알킬화반응을 고정층 반응기에서 행하였다. 반응속도는 흡착된 에틸렌 및 프로필렌과 수지내부로 흡수된 기체상의 벤젠이 반응하는 Rideal형태의 모델과 잘 일치함을 알 수 있었으며, 온도에 따른 반응속도상수의 변화로부터 에틸화 및 프로필화반응의 활성화에너지가 구하여졌다. 반응물중에 첨가된 물에 의한 억제작용을 관찰하였고, 프로필렌이 에틸렌보다 극성이 높아 겔상 미세입자내부로 침투가 용이함을 예상할 수 있어 에틸화반응보다 프로필화반응에서 높은 반응성을 나타냄을 확인하였다.
The vapor-phase alkylation of benzene with each of ethylene and propylene was carried out in a fixed-bed reactor by using two different macroreticular resin catalysts ; Amberlyst 15 and Amberlyst XN-1010. The reaction rates were shown to be correlated by the Rideal kinetics where the chemisorbed ethylene or propylene reacts with the absorbed benzene, and the activation energies of each alkylation were estimated. Water in the feed plays the role of inhibitor to the reaction, and it has been confirmed that the rate of propylation is faster than that of ethylation possibly due to the larger polarity of propylene and its corresponding easiness of permeation into the resin particle.
