酯化反应偶联渗透汽化膜反应器PPVA/PAN复合膜稳定性研究
Studying on the PPVA/PAN composite membrane stability of esterification coupled pervaporation process
摘要
Abstract
In esterification coupled pervaporation membrane reactor, effects of membrane material prop-erties, reaction-separation temperature，reaction mixtur e and catalytic sys tems on the membrane stability were all investigated. Experimental results showed that sulfuric acid and p-tol uene sulfonic catalyst had great effect on the membrane stability and the solid super acid catalyst had no effect on membrane stability. Composite membranes with the esterification degree of activity layer being 3.3% and 6.2% had well separation properties and stability and they were suit to the study and application of coupled membran e reactor.关键词
