activity at the water‐air interface and electrical conductivity of the resulting surfactants at 10, 20, 30 and 40 °C were determined and thermodynamic parameters of micellization and adsorption were calculated. It was established that the synthesized quaternary ammonium salts have the ability to localize thin crude oil films on the water surface formed due to spill.
辛醇,壬醇,癸醇和十二烷与表氯醇的反应在氢氧化钠作为催化剂的情况下进行。合成的非离子表面活性剂用三乙醇胺改性。测定了水-空气界面的表面活性以及所得表面活性剂在10、20、30和40°C时的电导率,并计算了胶束化和吸附的热力学参数。已经确定,合成的季铵盐具有将稀薄的原油膜定位在由于溢出而形成的水表面上的能力。
