| Hazard Information | Back Directory | [Definition]
ChEBI: Acetyl fluoride is an acyl fluoride that is fluoroethane carrying an oxo group at position 1. It is an acyl fluoride and an organofluorine compound. | [Preparation]
Acetyl fluoride (but not other acyl fluorides) is most conveniently prepared by addition of Acetyl Chloride to a solution of Potassium Fluoride in AcOH; reaction is immediate. Warming the solution and condensing the gas gives nearly quantitiative yields. Procedures applicable to the preparation of a variety of acyl fluorides include reaction of the acid chloride or anhydride with nucleophilic fluorides and fluorination of the carboxylic acid. | [storage]
Samples of acetyl fluoride sealed in glass ampoules slowly form a pyrylium salt.4 Acetyl fluoride is a corrosive lachrymator. Use in a fume hood. | [Purification Methods]
Purify acetyl fluoride by fractional distillation. It attacks glass and is sold in steel cylinders. [Beilstein 2 H 172, 2 I 79, 2 II 175, 2 III 385, 2 IV 393.] TOXIC and LACHRYMATORY. |
