摘　　要：以脂肪醇嵌段聚醚即一种脂肪醇聚氧丙烯聚氧乙烯醚、氨基磺酸为原料,尿素为催化剂,合成了硫酸酯盐延展型阴-非离子表面活性剂,采用红外光谱对其结构进行了表征,采用浊度法、滴体积法、分水时间法、分散指数法对其低温溶解性能、表面性能、乳化性能、分散性能进行了测定。采用单因素实验法,研究了反应温度、反应时间、催化剂用量、原料配比等因素对产物中活性物含量的影响,并确定了最佳合成反应条件。结果表明,在反应温度100℃、反应时间3 h、催化剂用量为反应物总质量的1%、n(嵌段聚醚)∶n(氨基磺酸)=1∶1.5条件下,产物中活性物含量达到96.49%。The structure of the surfactant was characterized by infrared spectroscopy,and its low-temperature solubility,surface properties,emulsification properties and dispersion properties were measured by turbidity,drop volume,water splitting time and dispersion index methods.The effects of reaction temperature,reaction time,catalyst dosage and raw material ratio on the content of active substances in the products were investigated by the single-factor experimental method,and the optimum synthesis reaction conditions were determined.The results showed that under the conditions of reaction temperature of 100℃,reaction time of 3 h,catalyst dosage of 1%of the total mass of the reactants and n(block polyether)∶n(sulfamic acid)=1∶1.5,the content of active substances in the products reached 96.49%.
