| Abstract: | The orthogonal experiment was employed to optimize preparation technology of ethoxylation reaction.To decrease the the level of free ethylene oxide in ethoxylated fatty alcohol surfactant series,we adjusted the dosage of catalyst and prolonged the aging time and the time of stripping based on the fixed production feeding.Results indicated that the content of dioxane in sulfonating agent can be controlled on lowlevel. |
