The studies by Campbell27 showed a clean Ag(111) surface had a selectivity of 36-48%, while clean Ag(110) surface has a selectivity of 36-39% toward ethylene oxide formation depending on the reaction temperature. Kestenbaum et al.,14 while synthesizing ethylene oxide in a catalytic ...
The reaction of carbon dioxide (CO2) with ethylene oxide (EO) in the presence of organotin compounds, such as organotin halides (RnSnX4−n; R=Alkyl, Aryl, X=Br, Cl, n=2,1) or organostannoic acids ((RSnOOH)n; R=Alkyl, Aryl) yielded ethylene carbonate (EC) as a product in fai...

A method of preparing 3- β -hydroxyethyloxazolidone-2 from ethylene oxide and oxazolidone-2 under pressure in an autoclave, at 72–75° in aqueous medium, is described.doi:10.1007/BF00473620I. S. MatveevN. N. PolitunKluwer Academic PublishersChemistry of Heterocyclic Compounds...
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...
Glaser coupling reaction of alkynyl groups was used as a new ring-closure technique to synthesize monocyclic poly(ethylene oxide) (PEO) and polystyrene (PS) successfully. The linear PEO with hydroxyl groups at both ends was prepared by ring-opening polymerization (ROP) of ethylene oxide (EO) us...
Molecular dosimetry of ethylene oxide: formation and persistence of N-(2-hydroxyethyl)valine in hemoglobin following repeated exposures of rats and mice. The formation of N-(2-hydroxyethyl)valine (HEVal) in hemoglobin was investigated in male F344 rats (10/group) and B6C3F1 mice (20/group) ...
10.2). First, the nucleophilic attack on the EC forms a radical-terminated linear carbonate ethylene oxide, a PEO oligomer radical. This radical anion can polymerize to form longer chained PEO- based polymers. Second, the evolution reaction results in ethylene oxide radical [94] that can also ...
HDPE is manufactured at low temperatures and pressures, using Ziegler-Natta and metallocene catalysts or activatedchromiumoxide (known as a Phillips catalyst). The lack of branches in its structure allows the polymer chains to pack closely together, resulting in adense, highly crystalline material of...
