1122ethanediol

1,1,2,2-Ethanediol, also known as vicinal glycol, is an organic compound with the chemical formula C2H6O2. It is a diol, meaning it contains two hydroxyl (-OH) groups. In this specific isomer, the two hydroxyl groups are attached to adjacent carbon atoms. This arrangement distinguishes it from other ethanediol isomers such as 1,2-ethanediol (ethylene glycol).

The physical properties of 1,1,2,2-ethanediol are not as widely documented as those of its more common isomer, 1,2-ethanediol. It is expected to be a colorless liquid or solid at room temperature, with a relatively high boiling point due to hydrogen bonding between the hydroxyl groups. Its solubility in water and polar organic solvents is also anticipated to be high.

Due to the vicinal arrangement of the hydroxyl groups, 1,1,2,2-ethanediol can undergo specific chemical reactions. Oxidation, for example, can lead to the formation of glyoxal, a dialdehyde. The presence of two hydroxyl groups on adjacent carbons also makes it a potential precursor for cyclic compounds under certain reaction conditions.

1,1,2,2-Ethanediol is not as commercially significant as 1,2-ethanediol, which is widely used as antifreeze and in the production of polyester fibers. The synthesis and applications of 1,1,2,2-ethanediol are less prevalent, making it a less studied compound in industrial and academic settings. Research into its specific properties and potential uses may be ongoing, but it remains a less common isomer of ethanediol.
