| 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. |
| 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. |
