Difluoroacetic acid is a chemical compound with chemical formula CHF2COOH.
Contents
Properties
Chemical
Difluoroacetic acid reacts with bases to form the corresponding difluoroacetate salts.
Physical
Difluoroacetic acid is a colorless liquid, miscible with water and alcohols.
Availability
DFA is sold by lab suppliers.
Preparation
Can be prepared by refluxing potassium fluoride with dichloroacetic acid.
Projects
- Make difluoroacetate salts
- Compound collecting
Handling
Safety
Difluoroacetic acid is toxic, though less so than its monofluoroacetic derivate. Chronic exposure has been linked to nerve and liver damage.
Storage
In closed bottles, with a PTFE seal and a hazardous chemical label.
Disposal
Should be neutralized with a base. The resulting salts should be taken to waste disposal facilities or recycled.
