Ethylene oxide scrubber: After the gaseous stream from the main reactor, containing ethylene oxide (1–2%) and CO 2 (5%), is cooled, it is then passed to the ethylene oxide scrubber. Here, water is used as the scrubbing media which scrubs away majority of ethylene oxide along with some amounts of CO 2 , N 2 , CH 2 =CH 2 , CH 4 and aldehydes ...
Ethylene oxide is widely used to generate detergents and surfactants by ethoxylation. Its hydrolysis affords ethylene glycol. It is also used for sterilisation of medical instruments and materials. The reaction of epoxides with amines is the basis for the formation of epoxy glues and structural materials.
Ethylene is oxidized to produce ethylene oxide, a key raw material in the production of surfactants and detergents by ethoxylation. Ethylene oxide is also hydrolyzed to produce ethylene glycol, widely used as an automotive antifreeze as well as higher molecular weight glycols, glycol ethers, and polyethylene terephthalate.

Steritec, located at 1705 Enterprise St., uses ethylene oxide to sterilize medical equipment and materials. According to the EPA, pollution is increasing health risks in the area. During the ...
The reaction typically proceeds by blowing ethylene oxide through the alcohol at 180 °C and under 1-2 bar of pressure, with potassium hydroxide (KOH) serving as a catalyst. [5] The process is highly exothermic (ΔH = -92 kJ/mol of ethylene oxide reacted) and requires careful control to avoid a potentially disastrous thermal runaway. [5]

To make NPEs, manufacturers treat NP with ethylene oxide under basic conditions. [12] Since its discovery in 1940, nonylphenol production has increased exponentially, and between 100 and 500 million pounds of nonylphenol are produced globally every year, [ 12 ] [ 16 ] meeting the definition of High Production Volume Chemicals .
Altria used to own over 10% of Anheuser-Busch InBev S.A. , the world's largest brewer. The company sold 35 million of its 197 million shares through a global secondary offering earlier this year ...
