Beschreibung

Allgemeine Beschreibung

Dichloromethane has been tested as a solvent medium for the dipyridine-chromium(VI) oxide. Solubility was reported to be 12.5g/100ml. Role of the quantity of TiO₂ loading on activated carbon support on its photodecomposition has been investigated.

Anwendung

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