Abstract

The present invention relates to a process for the preparation of 1,2-bis-(2-nitrophenoxy)-ethane, by reacting 1 mole of ethylene glycol with about 190 to about 250 mol % of 2-chloronitrobenzene at temperatures of about 40.degree. to about 100.degree. C. with the addition of an alkali metal hydroxide in dimethylacetamide.
