Abstract The ethoxylation is the common technology in preparation of methoxypolyethylene glycol. The principle and production technique of ethoxylation were introduced, and the specification operation was introduced in detail. The safety problems in the production technique and the safety measures were also summarized.The craft process of production accidents and the influence degree of the accident were reduced. The reliable safeguard for enterprise's safety production was provided.
