Study on the Efficient Preparation Method of C16 Gilbert Alcohol Polyoxyethylene Ether Sulfate
C16 Guerbet alcohol polyoxyethylene ether(C16GA-PE)was prepared by copolymerization,and then sulfated with aminosulfonic acid to obtain C16GA-PES.This method can effectively reduce product viscosity and improve sulfation efficiency.The prepared C16GA-PES can significantly reduce the surface tension of aqueous solution and the interfacial tension of oil/water.At the critical micelle concentration(about 0.1%),it drops to 32.2 mN/m and 2.3 mN/m,respectively,demonstrating excellent interfacial activity.
