The sulphobetaine has structure of strong acid groups which were tipical anion and cation ampho-surfactant. It has advantages of acid and alkali resistant, better lime soap dispersing, hypotoxicity and good chemi-cal stability. It has bright future in daily chemicals and other industries. A synthetic process for a new kind of sur-factant:ditetradecyl sulphobetaine. The effects of reaction time, temperature on yield were investigated. The struc-ture was detected by IR. The optimal conditions were 125℃, 16h, the yield was 95.8%.
