Chloroform - Wikipedia

Deuterated chloroform is an isotopologue of chloroform with a single deuterium atom. CDCl 3 is a common solvent used in NMR spectroscopy.Deuterochloroform is produced by the haloform reaction, [citation needed] the reaction of acetone (or ethanol) with sodium hypochlorite or calcium hypochlorite. The haloform process is now obsolete for the production of ordinary chloroform.

Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. Once formed, the methyl chloride may undergo further chlorination to form methylene chloride (CH2Cl2), chloroform, and carbon tetrachloride. A methyl chloride production process consists of a reactor, a condenser, a distillation column, and an absorption column.

10.22: Distillation - Chemistry LibreTexts

How Does Fractional Distillation Work? | Sciencing

Distillation is the process of separating two or more liquids based on differences in their boiling points. When the liquids' boiling points are very similar, however, separation by normal distillation becomes ineffective or impossible. Fractional distillation is a modified distillation process that allows the .

Distillation - University of Massachusetts Amherst

distillation is the presence of a "fractionating column" in the fractional distillation. In a distillation, liquid is converted to vapor by heating and the vapor is then condensed back to liquid by cooling. In a simple distillation this is done one time. In a fractional distillation, as the vapor ascends the
