Benzotrifluoride is a chemical compound selected from the group consisting of aromatic fluorocarbons. It is a colorless, volatile, flammable and almost odorless liquid.

Production and representation

Benzotrifluoride can be prepared by fluorination of benzotrichloride.

Properties

Physical Properties

Benzotrifluoride is a colorless, highly flammable liquid which is very poorly soluble in water. The boiling point at atmospheric pressure is 102.3 ° C. The vapor pressure function is given by Antoine corresponding log10 (P) = A- ( B / ( T C)) (P in Torr, T in K) with A = 6.642, B = 1148.7 and C = -70.9 in temperature range of 2 ° to 80 ° C. The compound has a calorific value of 4.6 kWh / kg. The vapors of Benzotrifluoride are 5.05 times heavier than air.

It reacts with hot water, forming hydrofluoric acid and benzoic acid.

Use

Benzotrifluoride serves as a starting material for the production of herbicides, dyes and pharmaceuticals, such as the intermediate m- chlorobenzotrifluoride C7H4ClF3 ( CAS: 98-15-7 ) and Benzotrifluoridisocyanaten. It is further used as a solvent.

Safety

Benzotrifluoriddämpfe combine with air to form an explosive mixture (flash point 12 ° C, ignition temperature 620 ° C).
