| Abstract: |
| The paper introduces the rapid growth of ethylene oxide production capacity and ethoxylation plants. Technology improvement， weakness and process characteristic of internal ethoxylation have been summarized. The performances and applicable conditions of different ethoxylation processes are compared and analyzed. The current situation about production accidents, government regulation and engineering design are very grim, so the requirements about construction and operation of ethoxylation plants are very high. Especially，explosive polymerization of ethylene oxide has brought serious harm to production of ethoxylate, and some solutions are proposed. |
