| Abstract: | The tilled compound used as nonionic surfactant was synthesized by reaction of stearic acid with phosphorous trichloride and reaction of obtained stearyl chloride with polyethylene glycol(400). The effects of molar ratio of reactants, time and temperature on the reaction have been examined. The reaction was carried out at 100 C for 1.0 h with a ratio of stearyl chloride /polyethylene glycol = 1.1 :1. |
