Abstract

반응기내에 정적믹서를 장착하여 반경방향 혼합을 유도함으로써 유체의 흐름을 plug flow형태와 유사하게 가질 수 있는 충진 관형 반응기에서 메틸메타아크릴레이트의 자유라디칼 중합에 대하여 연구하였다. 충진 관형 반응기의 성능이 모사실험에 의해서 조사되었다. 반응 초기의 전이상태와 정상상태가 모사실험에 의해서 모두 조사되었다. 모사실험결과 CSTR 반응기보다 모노머 전환율이 높은 60% 저도까지 사용 가능함을 보여주고 있다. 또한 충진 관형 반응기의 관내경이 최적 크기는 2.54cm이다. 모사실험결과는 충진 관형 반응기가 메틸메타아크릴레이트의 중합을 위한 연속 중합 반응기로 사용 가능함을 보여주고 있다. 그러므로 본 연구에서 충진 관형 반응기를 이용한 메틸메타아크릴레이트의 연속 중합 공정이 상업적으로 이용 가능한 새로운 공정임을 보여주고 있다.

Free radical polymerization of methylmethacrylate was studied using filled tubular reactor with some axial dispersion effect, such as a near plug flow pattern, due to intensive radical mixing induced by static mixers. It was of interest to investigate how the performance of the filled tubular reactor has been investigated by model simulations. Both start-up transient and steady state behaviors of reactor were investigated through model simulations. The model simulation results in continuous filled tubular reactor could obtain the monomer conversion of 0.6, which was higher than in CSTR. And the optimalinside diarmeter of filled tubular reactor was 2.54cm. The model simulation results suggested that the filled tubular reactor could be potentially a good continuous reactor for the polymerization of methlmethacylate. In this study, the filled tubular reactor was potentially a very important new polymerization technology.
