Synthesis and Surface Activity of Biomass Cardanol Sulfonate Surfactant

摘要：

A novel biomass cardanol sulfonate surfactant was synthesized using cardanol and oleum as raw materials, dichloromethane as solvent. The IR characterization result has proved the occurrence of sulfonation on the benzene ring of cardanol which has given a product of cardanol sulfonate. The evaluation on the surface activity of the product has shown that the values of the surface tension and critical micelle concentration (cmc) were 38.41 mN/m and 3.37 g/L, respectively. Interfacial tension of cardanol sulfonate aqueous was measured by spinning droplet method, the results showed that the value of interfacial tension reached 8.6×10-2 mN/m when the salt content was 1％, when the alkali content was 1.2％, the value reached 1.4×10-2 mN/m.
