在教学实践的基础上，推荐一个适合高职院校精细化工专业学生的实验---十二烷基硫酸钠的制备。以浓硫酸和尿素为催化剂，用月桂醇(正十二醇)和氨基磺酸反应，然后加入氢氧化钠放尽氨气，所得粗产物，经提纯、干燥精制得白色或淡黄色固体。通过实验可以让学生掌握硫酸化制备阴离子表面活性剂的基本原理和方法，并掌握尾气吸收、提纯等精细化工实验操作技能。

Based on the teaching practice, a fine chemical experiments was recommend, it's suitable for advanced vocational students———the synthesis of sodium dodecyl sulfate. Using sulfuric acid and urea as catalyst, lauryl alcohol ( lauryl alcohol) and amino sulfonic acid were reacted, and sodium hydroxide was put ammonia, so the coarse product was gotten, and then, the white or light yellow solid were obtained by purification and drying. Through the experiment can make the students master the basic principle of sulfating preparation of anionic surfactant and methods, and grasp the experimental operation skills of fine chemical industry, such as the tail gas absorption and purification .
