Unique fourth-order kinetics for the reactions of ethylene oxide with water, and ethylene oxide with ethylene glycols were derived and validated, as were kinetics for the reactions of neat ethylene oxide and the decomposition of ethylene glycols. The latter data was incorporated into a reaction ...
Ethylene oxide may react with water and be hydrated to ethylene glycol in accordance with the following reaction10 Sign in to download full-size image The reaction proceeds with the aid of acid catalysts, while the reaction temperature ranges between 60 to 100°C. ...
Ethylene glycol and ethylene carbonate (EC) are not bio-liquids, but they are produced from ethylene oxide by reaction with water and CO2 respectively. Ethylene oxide is produced by catalytic, soft oxidation of ethylene. Comparison of dissolution kinetics of cellulose (mass % of solids residue) ...
A lot of water was used in the hydrolysis reaction of ethylene oxide at the early stage of the polymerization and transformed into ethylene glycol (EG), which was consumed subsequently through a chain transfer reaction. EG was more reactive both than 1,4-butylene glycol and hexamethylene ...
metalllc potassium, acids, covalent halides (e.g., aluminum chloride, iron(Ⅲ) chloride, tin(rv> chloride, aluminum oxide, iron oxide, rust). Explosive reaction with glycerol at 200℃. Rapid compression of the vapor with air causes explosions. Incompatible with bases, alcohols, air, m-nitro...
Ethylene oxide is made by contacting ethylene and molecular oxygen with a silver catalyst at 150 DEG to 450 DEG , preferably at 200 DEG to 300 DEG C., 1 to 35 ats. absolute, in the presence of at least 15 mol. per cent of methane based on the total feed to the reaction zone. The...
A process for preparation of glycols in which the vapor remaining after the partial condensation of a conventional ethylene oxide stripper overhead vapor stream is contacted with an aqueous solution of ethylene carbonate to recover ethylene oxide. No water need be removed from the enriched ethylene ...
Niobium oxide (Nb 2O 5) supported on α-alumina (α-Al 2O 3) prepared by impregnation was studied for hydration of ethylene oxide. The effects of niobium oxide loadings, calcination temperature and molar ratio of water to ethylene oxide (EO) on the reaction performance were investigated. The...
The electrochemical production of ethylene oxide (EO) from CO2, water and renewable electricity could result in a net consumption of CO2. Unfortunately existing electrochemical CO2-to-EO conversions show impractical Faradaic efficiency (FE) and require a
DefinitionChEBI: A 1,2-glycol compound produced via reaction of ethylene oxide with water. Production MethodsHistorically, ethylene glycol has been manufactured by hydrolyzing ethylene oxide. Presently, it is also produced commercially by oxidizing ethylene in the presence of acetic acid to form ethylen...
