Contents
Properties
Chemical
Difluoroacetic acid reacts with bases.
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 KF with dichloroacetic acid.
Projects
- Make difluoroacetate salts
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.
