General description

Ethylene glycol diethyl ether (1,2-Diethoxyethane) is a polyether.[1] Its thermal desorption on Ru(001) surface has been reported to occur in 3 states. Desorption energy was reported to be 58-62kJ/mol.[2]

Application

Ethylene glycol diethyl ether may be used in the preparation of 1,4-dioxanes and alkyl chlorides, via reaction with NbCl5 at room temperature.[1]
