The latter data was incorporated into a reaction model useful for the determination of ethylene oxide storage stability and pressure relief … An ethylene glycol production follows the reaction between ethylene oxide and water at temperature of 200 °C and pressure of 20 bars to produce mono-ethylene glycol and other higher glycols derivatives. Dunkelberg H. Carcinogenic activity of ethylene oxide and its reaction products 2-chloroethanol, 2-bromoethanol, ethylene glycol and diethylene glycol. Amberjet 4200/HCO3− was used as the heterogeneous catalyst, which was found to be the most effective among the four types of cross-linked styrene−divinylbenzene anion-exchange resins tested. Characteristics of Block Copolymers of Methyl Oxirane and Oxirane Derivatives of 2-Ethylhexanol as Obtained with KOH and Dimetalcyanide Type Catalyst. Mikrobiol. In the present paper the kinetics of ethoxylation and of propoxylation of ethylene glycol catalyzed by KOH have been studied. The product recovery and purification consume water for the … More efficient direct oxidation of ethylene by air was invented by Lefort in 1931 and in 1937 Union Carbide opened the first plant using this process. The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online. A kinetic model has been developed for taking into account this peculiar behavior and the corresponding kinetic parameters have been determined. Learn more. Abbas Azarpour, Sohrab Zendehboudi, Suzana Yusup, Athirah Khalid, Yahui Zhang. This more efficient routine accounted for about half of ethylene oxide production in the 1950s in the US, and after 1975 it completely replaced the previous methods. Some features of the site may not work correctly. Ethylene oxide is one of the most important intermediates in the chemical industry, being used for reactions with ethylene, water, alcohols and organic acids. Quantum chemical study on anionic polymerization mechanism of propylene oxide. Kinetic data on the hydration of ethylene oxide was obtained from both uncatalyzed and heterogeneously catalyzed reactions using a pressurized batch reactor. You are currently offline.
