说明

一般描述

Chloroform 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.

应用

Chloroform may be 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.
• Solvent for recrystallization.
• As a reference compound to detect the presence of chloroform in tobacco smokes.
• As an extractant in solvent extraction process.

包装

4×4 L in PVC-coated bottle
