| 摘 要： | 以甲苯为溶剂,用金属钠和椰油醇聚氧乙烯(3)醚反应生成醇纳,再与2-氯乙基磺酸钠反应合成了椰油醇聚氧乙烯醚磺酸钠(CAPES),产率达到82%左右.产品经红外光谱和质谱表征为C12/C14醇聚氧乙烯醚(n)磺酸盐(n=1～8).性能研究表明,CAPES在中性或微碱性水介质中于80℃下存放96 h,稳定度达到97%以上,明显高于AES;45℃下对NaCl,CaCl2,MgSO4的容忍度分别达到115,167,300g/L以上,与AES相当;CAPES微乳液的最佳盐度(NaCl)和中相盐宽亦与AES接近,耐盐能力明显高于重烷基苯磺酸盐类表面活性剂;CAPES的表面活性与AES相当,明显高于SDS;通过与两性表面活性剂复配,无需添加任何碱和中性电解质,可使大庆原油/水界面张力降到10-3mN/m数量级.

| Abstract: | Polyethoxylated coconut fatty alcohol reacted with metallic sodium in benzene as reaction medium to form sodium polyethoxylated coconut fatty alcoholate,and the latter further reacted with 2-chloroethanesulfonate in toluene as solvent to form the product sodium polyethoxylated coconut fatty alcohol sulfonate(CAPES) with a yield of 82% achieved.Characterized by IR and MS,the final product was proved to be mixed homologues of sodium polyethoxylated C12/C14 alcohol sulfonates with n between 1 to 8.Examination ... |
