Descrição

Descrição geral

Chloroform is a is a colorless, volatile chlorinated organic solvent whose vapors have 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. Spectrophotometric grade chloroform shows low UV absorption which makes it an ideal solvent for spectrophotometry.

Aplicação

Chloroform (spectrophotometric grade) was used in the following processes:

• Synthesis of colloidal hydrophobic CdSe core nanocrystals (quantum dots).
• Preparing phospholipid solutions.
• As a solvent in the photolysis reaction of ruthenium complexes.

It may be used as:

• Solvent for recrystallization.
• Reference compound to detect the presence of chloroform in Tobacco smokes.
• Extractant in solvent extraction process.
