12Difluoroethane

1,2-Difluoroethane, also called ethane-1,2-difluoride, is an organofluorine compound with the chemical formula C2H4F2. It features two fluorine atoms attached to adjacent carbon atoms of the ethane backbone, typically represented as CH2F–CH2F. The molecule is symmetrical and achiral.

In terms of physical properties, 1,2-difluoroethane is a colorless, volatile substance that exists as a gas under standard conditions. It has a boiling point well below room temperature and exhibits low solubility in water, while being more soluble in many organic solvents and hydrocarbons. It is a relatively nonpolar molecule with limited hydrogen-bonding potential.

Industrial production of 1,2-difluoroethane occurs through fluorination processes that convert ethane or related hydrocarbon feedstocks, often under specialized catalytic or photochemical conditions. It is used as an intermediate in the synthesis of other fluorinated compounds and can serve as a precursor in various organic transformations that introduce difluoromethyl or difluoroethyl groups.

Safety and environmental considerations are important when handling this compound. It is a volatile chemical that can pose health risks if inhaled in high concentrations, and spills should be managed with appropriate containment. Fluorinated hydrocarbons, including difluoroethanes, can have environmental impacts such as contributing to atmospheric greenhouse warming, leading to regulatory and handling considerations in industrial settings.
