摘要： 以妥尔油和浓硫酸为原料制备硫酸化妥尔油表面活性剂。通过单因素试验考察了反应时间、反应温度、反应转速和浓硫酸与妥尔油摩尔比对硫酸化妥尔油表面活性剂泡沫性能的影响,并探讨了不同碱中和剂对其泡沫性能和表面张力的影响。结果表明,硫酸化妥尔油的较佳合成条件为:反应时间6 h,反应温度40 ℃,反应转速600 r/min,浓硫酸与妥尔油摩尔比为1∶5;采用N-甲基二乙醇胺中和所得硫酸化妥尔油表面活性剂的起泡性和稳泡性较佳,发泡体积为350 mL,半衰期为27 min;不同碱中和后所得表面活性剂的表面张力均在28~33 mN/m之间;将较佳条件下制备的硫酸化妥尔油表面活性剂经N-甲基二乙醇胺中和后与硬脂酸铵进行复配,当m(硬脂酸铵)∶m(硫酸化妥尔油)=3∶2时,发泡体积达到550 mL,半衰期为35 min。

Abstract: Sulfated tall oil surfactant was prepared with tall oil and concentrate sulfuric acid as starting materials.The influences of reaction time,temperature,stirring rotation speed and molar ratio of sulfuric acid to tall oil on the foaming performance of the surfactant were investigated via single-factor experiments.Results showed that the recommended conditions are:reaction time,6 h;reaction temperature,40 ℃;reaction stirring rotation speed,600 r/min;and molar ratio of sulfuric acid to tall oil,1∶5.Meanwhile,different kinds of neutralizing agent were tested for making the surfactant product and results showed that surface tension of all the surfactant products achieves 28-33 mN/m,but that neutralized with N-methyldiethanolamine displays the best foaming power of 350 mL and best foam stability of 27 min half-life period.Blend of such surfactant product with ammonium stearate at a mass ratio of 2∶3,the foaming power achieves 550 mL foam stability of 35 min half-life period.

Key words: surfactant, sulfated tall oil, preparation, foaming performance
