摘要
以丙烯腈、异丁烯、硫酸为原料中试合成了2-丙烯酰胺-2-甲基丙磺酸（AMPS），考察了磺化条件、异丁烯的用量、反应温度、溶剂用量等条件对AMPS产品的收率和外观的影响，得到了中试合成AMPS的最佳工艺条件：硫酸质量分数100％，m（异丁烯）：m（H2s0。）=0．6，控制加入硫酸时的温度为-5～0℃，加入异丁烯时的温度为35—40℃，m（丙烯腈）：m（异丁烯）=6，反应时间4h，AMPS的收率90．7％～94．5％。
2-acrylamido-2-methyl propane sulfonic acid（AMPS） has been pilot-synthesized by using acrylonitrile, isobutylene and sulfuric acid as raw materials. The effects of the conditions of sulfonation, dosage of isobutylene, re- action temperature and volume of solvent, etc, on the yield and exterior appearance of AMPS have been investigat- ed. The optimum process conditions of the pilot-synthesized AMPS are obtained. And the mass fraction of sulfuric acid is 100%, m （isobutylene）：m （H2SO4）=0.6,-5-0 ℃ is the temperature controlled when sulfuric acid is added, and 35-40 ℃ is the temperature controlled when isobutylene is added, m （acrylonitrile）：m （isobutylene）=6, reaction time=4 h. The yield of AMPS is between 90.7%-94.5%.
