HCID 16704Diglycidyl ether

Procedure

One mole of tetradecanol ethoxylated with 2 moles of ethylene oxide per mole of tetradecanol and one mole of epichlorohydrin were reacted in the presence of tin tetrachloride at a temperature of 60 to 70° C. and a glycidyl ether was obtained. A solution of 30% sodium hydroxide in water was added at 80° C. After 30 minutes under vigorous stirring at 80° C., the resulting glycidyl ether was separated from the water phase. It had the structure
