General description

Chloroform is a colorless, volatile chlorinated organic solvent whose vapors have narcotic effect.[32] It is susceptible to degradation with time which can be suppressed by adding ethanol as a stabilizer. Since ethanol is added in higher concentration it leads to increase in polarity which may have a potential influence on some of the applications.

Application

Chloroform may be used in the following processes:
  • Synthesis of colloidal hydrophobic CdSe core nanocrystals (quantum dots).
[38]
  • Preparing phospholipid solutions.
  • [39]
  • As a solvent in the photolysis reaction of ruthenium complexes.
  • [40]
  • Solvent for recrystallization.
  • [41]
  • As a reference compound to detect the presence of chloroform in tobacco smokes.
  • [42]
  • As an extractant in solvent extraction process.
  • [43]
