Descrição geral

Dichloromethane has been tested as a solvent medium for dipyridine-chromium(VI) oxide. Solubility was reported to be 12.5g/100ml. The apparent adsorption constant of the TiO2 loaded activated carbon for dichloromethane was found to be inversely proportional to the quantity of loaded TiO2.

Aplicação

Dichloromethane may be used as a solvent for the preparation of stock solutions of carotenoids. It may be employed as a solvent in the synthesis of polylactide-based (PLA) thin films.
