Chloroform - Wikipedia

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.

The traditional approach to solvent selection in the extractive distillation process strictly focuses on the change in the relative volatility of light-heavy components induced by the solvent. However, the total annual cost of the process may not be minimal when the solvent induces the largest change in relative volatility. This work presents a heuristic method for selecting the optimal .
