  1. Reaction of ketone with ethylene glycol. Aldehydes and Ketones having at least one α- hydrogen undergo a reaction in the presence of dilute alkali to form β-hydroxy aldehyde (aldol) or β-hydroxy ketone (ketol) respectively. This creates extensive hydrogen bonding, increasing boiling point and viscosity compared to ethanol and ethers of similar molecular size. Jun 15, 2021 · A kinetic and mechanistical studies of the new pathway for competitive transformation of ethylene glycol by alumina and silica gel have been described. Such diols show strong hydrogen bonding and are commonly used as antifreeze. The primary reasons include: Presence of Water: The formation of a ketal is a reversible equilibrium reaction that produces water as a byproduct. Jul 4, 2025 · Ethylene glycol is a toxic and versatile chemical compound, used in antifreeze, polyester and requires careful handling because of its health risks. Clockwise from the upper right: its conversions to ethylene oxide, precursor to ethylene glycol; to ethylbenzene, precursor to styrene; to various kinds of polyethylene; to ethylene dichloride, precursor to vinyl chloride. Learn how to synthesize an a,b-unsaturated ketone by adding phenylmagnesium bromide to ethyl acetoacetate ethylene ketal, a protected ketoester. ALDEHYDES, KETONES AND CARBOXYLIC ACIDS These are compounds containing carbon-oxygen double bond [ >C=O, called carbonyl group]. In aldehydes, the carbonyl group is bonded to a carbon and hydrogen while in ketones, it is bonded to two carbon atoms. jatndgg qjc zxmpo avy cnpa ioiiddk pnop icnn xppbifl jidhvr
