摘要/Abstract

摘要：

将聚合单体丙烯酸异辛酯（EHA）和化学交联剂苯二乙烯（DVB）溶于环己烷，通过γ射线引发聚合制备吸油树脂，并采用热重分析（TGA）和傅里叶红外光谱（FTIR）对树脂热稳定性和官能团进行分析。在此基础上，通过吸附实验系统研究吸油树脂对脂肪烃、芳香烃、酮类、醋酸酯类、醚类、卤代烃以及燃料油等典型有机化学品的吸附性能。结果表明，吸附对象的相对分子质量以及分子极性是决定吸油树脂吸附性能的两大重要因素；该吸油树脂对大部分有机化学品表现出良好的吸附效果，吸油倍率在10~30 g/g，其对于三氯甲烷的吸油倍率高达50.48 g/g。

Abstract:

An oil absorption resin was synthesized through initiation with a gamma ray using 2-ethylhexyl acrylate as a monomer， divinylbenzene （DVB） as a chemical crosslinker， and cyclohexane as a solvent， and its thermal stability and typical functional groups were analyzed by thermogravimetric analysis and Fourier-infrared spectroscopy. Furthermore， its absorbency performance for some typical organic chemicals such as aliphatic hydrocarbons， aromatic hydrocarbons， ketones， acetates， ethers， halogenated hydrocarbons and fuel oils were investigated through adsorption experiments. The results indicated that the molecular weight and polarity of organic chemicals were important factors for the absorbency performance of this resin. The oil absorption resin presented favorable absorbency to most of the organic chemicals with an absorption rat of 10~30 g/g， and it possessed an amazing absorption rate of 50.48 g/g to chloroform.

Key words: oil absorption resin, γ ray, irradiation polymerization, organic chemical
