一般描述

Chloroform is a colorless, volatile chlorinated organic solvent whose vapors have a narcotic effect.[1] 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. Reports suggest that chloroform stabilized with ethanol reduces chances on creating artifacts during the chromatographic separation after extraction of anthracyclines from biological matrices.[2]

应用

Chloroform was used as an organic phase in the methylene blue (MB) two-phase titration process for estimating the cationic surfactant content in high salinity brine.[3]
It may be used as:
  • Solvent for electropolymerization.[4]
  • Solvent for recrystallization.[5]
  • Extractant in solvent extraction process.[6]
