含有不同组分4A沸石粒子,0～10%海藻酸钠聚合物的溶液,通过溶液浇铸法制备了海藻酸钠的混合基质膜。膜用戊二酸醛交联,并评价在30～70℃下醋酸和乙醇的全蒸发脱水反应。在4A沸石较高负
The solution containing different components of 4A zeolite particles and 0 ~ 10% sodium alginate polymer prepared a mixed matrix membrane of sodium alginate by solution casting. Membranes were cross-linked with glutaric aldehyde and all-evaporative dehydration of acetic acid and ethanol was evaluated at 30-70 ° C. The zeolite 4A is higher negative
