Ethylene bisstearamide was prepared by the reactions of chloridization and amidation with stearic acid, thionyl chloride and ethylenediamine as raw materials. Influence of reaction temperature, reaction time and ratio of raw materials were discussed. The experimental results showed that the yield of ethylene bisstear- amide is up to 93.2% under the optimal reaction conditions of chloridization temperature 80 ℃, chloridization time 2.5 h, amidation temperature 95 ℃, amidation time 1.2 h, and stearic chloride to ethylenediamine mole ratio of 3 ： 1.
