General description
Chloroform is a colorless, volatile chlorinated organic solvent whose vapors have a narcotic effect. 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.
Application
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.
It may be used as:
• Solvent for electropolymerization.
• Solvent for recrystallization.
• Extractant in solvent extraction process.
