摘要:
在75 ℃及碳酸钾、碘化钾催化条件下，以相对分子量大、活泼氢多的甲基纤维素为主链，将聚乙二醇单甲醚(MPEG)接枝到主链上，形成具有梳型结构和超高分子量的环境友好的新型多糖类原油破乳剂.在梳型多糖类破乳剂合成过程中，选取4种不同分子量的MPEG（350，750，1 000，1 900），对甲基纤维素进行改性，从而合成梳型改性多糖破乳剂.通过红外光谱和核磁共振波氢谱进行结构分析，并用瓶试法测试破乳脱水性能，考察MPEG的分子量对破乳效果的影响.结果表明MPEG改性的甲基纤维素(MC\|O\|MPEG)具有很强的破乳性能， MC\|O\|MPEG(1900)的破乳性能最好，脱水率达到95.3%，脱水界面齐整，水层成浅白色.
Abstract:
Novel environmental friendly demulsifiers were synthesized by grafting polyethylene glycol monomethyl ether (MPEG) with different molecular weights (350,750,1 000 and 1 900) onto methylcellulose using potassium carbonate and potassium iodide as catalyst at reaction temperature of 75 ℃. The demulsifiers have comb structure, ultra\|high molecular weight and multi\|active hydrogens. The structures of the as\|prepared demulsifers were analyzed by fourier\|transform infrared spectroscopy and 1H nuclear magnetic resonance techniques, and the demulsification properties were tested by the bottle test method. Results show that methylcellulose modified by MPEG demonstrates a good demulsification performance; particularly, MC\|O\|MPEG(1 900) has the best demulsification performance among the four kinds of demulsifiers with the dehydrate rate of 95.3%. Following the breakage of crude oil emulsion, the neat dehydration interface and the light white color of water layer are observed.
