摘　　要：在降膜式磺化/硫酸化反应器中,异辛醇与SO3气体进行硫酸化反应,经氢氧化钠中和制得异辛醇硫酸钠。用红外光谱对产物结构进行了表征。正交试验考察各因素对反应转化率的影响,确定较优的合成条件为:异辛醇流量13.9 kg·h-1,SO3气体体积分数3%,反应器夹套水温度20℃,中和温度50℃。产品的性能测试结果显示其表面活性、渗透力、泡沫性能等与市售氨基磺酸硫酸化产品基本一致。lso -octanol was sulfated by SO3 gas in a fallingfilm sulfonation/sulfation reactor, and the intermediate was neutralized by NaOH solution to get the product sodium iso - octanol sulfate. Structure of the product was characterized by means of NTIR. Factors that influencing the product yield were investigated and optimum reaction conditions were identified by orthogonal designed experiment as： dosage of iso - octanol 13.9 kg ~ h -l, volume fraction of SO3 gas 3%, reactor jacket cooling water temperature 20 ~C, reaction temperature of neutralization 50℃. Performance indices, such as surface activity, wetting power and foaming performance et al. of the end product are basically coincide with that of product purchased from market that was prepared by aminosulfonic acid method.
