| Abstract: | A rosin-based cationic gemini surfactant is prepared from abietic acid,epichlorohydrin and N,N,N,N-tetramethyl-1,3-propanediamine through esterification and subsequent quaternary ammonium salification.The synthetic yield of the surfactant is 70.5% with a purity of 95.5%.Its structure is identified by FT-IR.The results of surface activity reveal that the prepared surfactant is a polymeric O/W emulsifier with good emulsifying properties and good compatibility with anions.Moreover,its foam is very dense and stable,and the critical micelle concentration(CMC),γcmc,pc20,HLB of the surfactant can reach to 4×10-4 mol/L,37.35 mN/m,4.45 and 13.98,respectively. |
