Ethanol to diethyl ether reaction
WebApr 13, 2024 · Diethyl ether is a by-product formed by reaction of two ethanol molecules over acidic catalysts. Conversion of ethanol to diethyl ether during glycerol ethylation depends on the reaction conditions, mainly on the reaction temperature and time. It yields mostly up to 20%. Diethyl ether also can act as an ethylation agent for glycerol. WebJul 15, 2015 · Reaction (1) suffers somehow of the competition with the production of diethyl ether (DEE): (2) 2 C 2 H 5 OH → C 2 H 5 OC 2 H 5 + H 2 O Δ H 298 = - 25.1 kJ / mol which is exothermic, also favored at low or moderate temperature. Over most catalysts, reaction (2) occurs very selectively at low temperature and conversion while reaction (1 ...
