General description

Diethyl ether (also known as ethyl ether or ether) is a laboratory solvent. It is a desirable solvent for oils, fats, waxes, perfumes, dyes, resins, hydrocarbons, and gums. It is also used as fuel and to synthesize other chemical compounds. DEE is widely employed as a solvent for Grignard synthesis.

Application

Diethyl ether is used as a solvent in the 3D-printed reaction ware device for chemical synthesis.
