大孔交联酰胺类聚合物是一类同时能提供氢键的给体(—NH—)和氢键的受体(—C O)的功能高分子材料。将D392乙酰化制得大孔交联聚(N-对乙烯基苄基乙酰胺)(PS-CH2NHCOCH3),并对其化学结构进行表征;测定了它在非水体系中对苯酚的吸附等温线,计算出不同吸附量时对应的吸附焓。结果表明,合成的大孔交联PS-CH2NHCOCH3在环己烷中对苯酚的吸附量大,吸附选择性高,排除了吸附过程的疏水作用及范德华力的影响因素,证明其吸附机理为氢键吸附。
Macroporous cross-linked amide polymers are a kind of functional polymer materials which can supply hydrogen bond (-NH-) and hydrogen bond acceptor (-C O) at the same time. The macroporous cross-linked poly (N-p-vinylbenzyl acetamide) (PS-CH2NHCOCH3) was obtained by acetylation of D392 and its chemical structure was characterized. The adsorption isotherm of phenol on non-aqueous system , Calculate the different adsorption capacity corresponding adsorption enthalpy. The results showed that the adsorption capacity of the macroporous crosslinked PS-CH2NHCOCH3 in cyclohexane was large and its adsorption selectivity was high. The hydrophobicity of the adsorption process and the influencing factors of van der Waals forces were excluded. The adsorption mechanism was found to be hydrogen bond Adsorption.
