CAS 359-13-7: 2,2-difluoroethanol

2,2-Difluoroethanol is a chemical compound with the molecular formula C2H4F2O. It is a colorless liquid that has a distinctive odor and is highly flammable. 2,2-Difluoroethanol reacts in an electrophilic substitution reaction to replace chlorine atoms with hydrogen atoms from the ethyl formate molecule. This reaction can be described by the following equation: CH3COOC2H5 + Cl → CH3COOC2H5Cl The activation energy for this reaction is 17.6 kcal/mol and it requires a strong acid catalyst such as phosphorus pentachloride to proceed. The mechanism of the reaction has not been definitively determined, but it may involve an intramolecular hydrogen bond between the hydroxyl group of one ethyl formate molecule and the chlorine atom of another ethyl formate molecule. The yield of this product depends on many factors including temperature, pressure,

Applications 2,2-Difluoroethanol is toxic. It has wide applications in pesticides, medicine and fluoropolymers, Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Jiang, Q., et al.: Zhejiang Huagong, 43, 5 (2012); Yukako, M., et al.: J.
