Abstract

Features of fractionation of reaction mixture in the synthesis of ethylene glycol by hydration of ethylene oxide in a reaction-rectification column are studied. Adequacy of the mathematical model applied to the process is evidenced. The ethylene glycol purity is shown depending on the process chemistry mainly. Side reaction of polyglycols formation restrict obtaining of high purity ethylene glycol: it can be isolated only as sideway stream in the bottom section of the reaction-rectification column.
