Popis

General description

Dichloroacetic acid (DCA) is a chlorinated acetic acid that has been reported to be a mouse liver carcinogen. The varying degrees of swelling of polyester in different concentrations of DCA solution has been analyzed by phase-contrast microscopy. The efficiency of titanium dioxide (TiO₂) nanoparticles to catalyze the photodegradation of DCA has been investigated.

Application

Dichloroacetic acid (DCA) can be used as:

• A reactant in the synthesis of chloroketones by reacting with esters in the presence of LiHMDS via Claisen-type homologation reaction.
• A structure-directing agent, solvent, or plastdopant for the preparation of different morphologies of polyaniline (PANI). Self-assembling nanostructured PANI may be formed due to the presence of strong hydrogen bonding between DCA and aniline/polyaniline.
