4A分子筛吸附甲基丙烯酸甲酯中水份的研究

摘要

The process of static adsorption of water and hydroquinone on 4A molecular sieve in methyl methacrylate (MMA) at different temperature were investigated. The saturated adsorption capacity of water on 4A molecular sieve in MMA with different water content were calculated and analyzed. The results showed that 4A molecular sieve activated at high temperature had good saturation adsorption on water and hydroquinone in MMA.%研究了不同温度下活化处理的4A分子筛对甲基丙烯酸甲酯中的水份、对苯二酚等其他杂质的吸附过程，详细测定分析了4A分子筛对不同含水量MMA的饱和吸附能力。结果表明，高温活化处理的4A分子筛对MMA中的水份和对苯二酚都具有很好的吸附效果。
