阳离子烷基糖苷的绿色合成及性能评价

摘要

采用先醚化、再季铵化的路线合成了阳离子烷基糖苷,n(环氧氯丙烷)∶n(蒸馏水)∶n(烷基糖苷)∶n(烷基叔胺)为1∶16∶1.5∶0.8,醚化条件为:95 ～ 100℃,2～4h,季铵化条件为:50～ 80℃,4～6h.系统研究了阳离子烷基糖苷的抑制性能,对于6％的阳离子烷基糖苷钻井液,岩屑一次回收率达96.35％,相对回收率达92.73％,相对抑制率达91.40％.%The route synthesis of cationic alkyl glucoside which was firstly etherification and then quatern-ization was determined, the rate of re(ECH) : re (distilled water) :n( APG) : n (alkyl tertiary amine) was 1 :16:1.5:0.8, etherification reaction conditions were: 95～100℃, 2～4 h, quaternary ammonium reaction conditions were: 50 ～ 80℃, ,4 ～6 h. For the drilling fluid including 6% cationic alkyl glucoside, cuttings first recovery was more than 96. 35% ,cuttings relative recovery was more than 92.73% ,the relative inhibition rate was 91.4% .
