摘要
采用分子印迹技术合成了噻吩分子印迹聚合物。研究了聚合物的吸附性能和识别性能,并考察了影响聚合物吸附性能的因素(如:功能单体、交联剂、溶剂以及模板分子与功能单体的摩尔比等)。结果表明:以噻吩为模板分子,α-甲基丙烯酸为功能单体,乙二醇二甲基丙烯酸酯为交联剂,氯仿为溶剂,反应温度60℃,在偶氮二异丁腈引发下合成的噻吩分子印迹聚合物对噻吩具有较好的吸附性能和识别特性,可为石油产品进行深度脱硫提供理论依据。
A molecularly imprinted polymer （MIP） for thiophene was prepared by a molecular imprinting technique. Influential factors on adsorption capability and recognition performance of MIP for thiophene, such as functional monomer, crosslinker types, solvent, molar ratio of template molecule to functional monomer, were investigated. The results showed that the imprinted polymers, prepared at 60 ~C by using α-methylacrylic acid as functional monomer, ethylene glycol dimethacrylate as crosslinker, chloroform as solvent and 2, 2＇-azobisisobutyronitrile as the initiator, exhibited good adsorption capacity and recognition performance for thiophene. This study may provide a theoretical basis for deep desulfurization of gasoline to remove sulfur-contained thiophenic compounds.
