Rbcs in 0.3m ethylene glycol
WebEthylene glycol is primarily used as a component of de-icer and anti-icer/anti-freeze fluid used in aircraft de-icing and anti-icing operations, and as an anti-freeze component in motor vehicles. It is also used in the manufacture of polyethylene terephthalate (PET) and in oil and gas processing. Ethylene glycol is present as a slow-evaporating ... WebThe Chemical Reaction of Ethylene Glycol. For carbonyl groups, ethylene glycol is used as a protective group. 1,3-dioxolane is produced by reacting a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst. This is resistant to nucleophiles and bases. Following that, acid hydrolysis operations remove the 1,3-dioxolane ...
