在不使用活化剂、引发剂或催化剂的情况下，通过本体聚合制备基于丙氧基甘油的亲油吸附剂。傅里叶变换红外光谱（FTIR），C-13和Si-29 CPMAS核磁共振（NMR），以及元素分析和热重分析（TGA）的操作，以确定吸附剂的结构和热特性。合成的凝胶被用作各种有机溶剂和油的吸附剂。的溶胀能力，吸附-解吸动力学，可重复使用性，并从油/水混合物的选择性去除进行了研究。为探讨交联剂浓度对吸油量的影响，以二氯甲烷为溶剂，采用不同浓度的三[3-（三甲氧基硅基）丙基]异氰脲酸酯（ICS）交联剂，对星星型丙氧基化物单体进行了反应，并计算了溶胀量。除油能力从水面是另一个重要的部分包含在这篇文章。(C)2017爱思唯尔有限公司版权所有。
Glycerol propoxylate based oil loving sorbents were prepared through bulk polymerization, without using of an activator, initiator, or catalyst. Fourier transform infrared spectroscopy (FTIR), C-13 and Si-29 CPMAS nuclear magnetic resonance (NMR), as well as elemental analysis and thermal gravimetric analysis (TGA) were operated in order to identify the structural and thermal features of sorbents. The synthesized gels were employed as absorbents for various organic solvents and oils. The swelling capacity, absorption-desorption kinetics, reusability, and selective removal from an oil/water mixture were also examined. To explore the effects of a crosslinker's concentration on oil absorption capacity, star type propoxylate monomers were reacted at different concentration of tris[3-(trimethoxysilyl)propyl]isocyanurate (ICS) crosslinker; swelling capacity was calculated using dichloromethane as an organic solvent. Oil removal ability from the water surface is another important section contained within this article. (C) 2017 Elsevier Ltd. All rights reserved.
