Abstract
This invention relates to the method for making ethylene oxide, characterized by the fact that ethylene oxide in the gaseous state is made to react with anhydrous gaseous hydrochloric acid, with the reaction medium likewise being maintained in the gaseous state during the reaction.
Claims5
The method of making ethylene chlorohydrin comprising forming a reaction mixture of gaseous ethylene oxide and anhydrous, gaseous hydrochloric acid and maintaining the reaction mixture in a gaseous state at a temperature of from about 130.degree. to 300.degree. C. during the reaction period.
The method of making ethylene chlorohydrin comprising introducing gaseous ethylene oxide and anhydrous, gaseous hydrochloric acid, each at a temperature of from about 50.degree. to 120.degree. C., into a reaction zone to form a reaction mixture, maintaining the reaction mixture at a temperature of from about 130.degree. to 250.degree. C. and at atmospheric pressure for a time sufficient for the reaction to be substantially completed, and separating ethylene chlorohydrin from the reaction mixture;
- the molar ratio of hydrochloric acid to ethylene oxide introduced to the reaction zone being from 2:1 to 20:1.
