说明

一般說明

Chloroform, a halogenated hydrocarbon, is widely employed as a solvent. Its photochemical degradation has been investigated in the presence of TiO₂ aqueous suspensions (wavelength range of 310-380nm).

應用

Chloroform may be employed as a solvent for the following studies:

• Extraction of RNA from plant cells.
• Preparation of dioleoylphosphatidylcholine (DOPC) solution.
• Dissolution of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC).

It may be employed in a rapid quantitative method for the release of periplasmic proteins from bacterial strains.

Chloroform may be used as a solvent to enhance the enantioselectivity of secondary alcohols formed by the borohydride reduction of carbonyl compounds in the presence of optically active ketoiminatocobalt complexes.
