Hydrochloric Acid → Diglycidyl ether

Participants

Reaction Steps

In a three-liter three-neck glass reaction flask, equipped with a thermometer, stirrer, condenser and dropping funnel were placed cyclohexane dimethanol, toluene and the catalyst. Epichlorohydrin was then added gradually through the dropping funnel to the mixture at such a rate that the temperature varied from 70° to 90° C., with external cooling being applied to the flask. Sodium hydroxide was then added which dehydrohalogenated the chlorohydrin intermediate and neutralized the formed hydrochloric acid. After removal of salt, the mixture was dried and filtered to yield pure diglycidyl ether of cyclohexane dimethanol. The weight per epoxide of the reaction product was 158 to 168, with a viscosity of 60 to 70 centipoise.
