Descrição

Descrição geral

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

Aplicação

Dichloromethane may be used in ultrasonic baths for cleaning and protection of aluminum coating over atactic-PMMA (poly(methyl methacrylate)) for dielectric studies.
