Hyperbranched polyglycerol polymers (HPG) were synthesized, characterized, and used to separate gasoline from deionized water. The study indicates HPG as potentially effective materials for the recovery of oil from oil/water emulsion. High and low molecular weight HPG were synthesized using the cationic ring‐opening polymerization method and characterized by various methods including, NMR, Fourier transform infrared‐spectroscopy, DXR Raman microscope, carbon hydrogen and nitrogen analysis, gel permeation chromatography measurements, biodegradability, and toxicity testing. The prepared polymers are environmentally friendly, biodegradable, and are able to recover up to 90.30% of oil from oil/water emulsion under an optimized dose of 500 mg L⁻¹ in 1 h. A higher rate of removal can be achieved by increasing the polymer dose up to 200 mg L⁻¹, with a reaction time up to 3 h, and a maximum operating temperature of 60°C. The results of this study offer a simple and effective technology that can be applied for the removal of valuable products, increase the profitability for the oil and gas industry, and protect the environment. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

利用环保的超支化聚甘油聚合物将汽油与去离子水分离

合成，表征了超支化聚甘油聚合物（HPG），并用于从去离子水中分离汽油。研究表明HPG是从油/水乳液中回收油的潜在有效材料。高分子量和低分子量HPG使用阳离子开环聚合方法合成，并通过多种方法进行表征，包括NMR，傅立叶变换红外光谱，DXR拉曼显微镜，碳氢和氮分析，凝胶渗透色谱法测量，生物降解性和毒性测试。所制备的聚合物是环境友好的，可生物降解的，并且能够以500 mg L ^-1的最佳剂量从油/水乳液中回收高达90.30％的油。在1小时内 通过将聚合物剂量增加到200 mg L ^-1，反应时间最多3小时，最高工作温度为60°C，可以实现更高的去除率。这项研究的结果提供了一种简单有效的技术，可用于去除有价值的产品，提高石油和天然气行业的利润率以及保护环境。©2020年化学工业协会和John Wiley＆Sons，Ltd.
