| Application: | Dichloromethane has been used for the quantification of herbivore (gypsy moth) induced blueberry volatiles by gas chromatography (GC). |
| Application: | Dichloromethane may be used as a solvent for the oxidation of primary and secondary alcohols using dipyridine-chromium(VI) oxide. Lithium perchlorate suspended in DCM is an effective medium for Mukaiyama aldol reactions of aldehydes with silyl ketene acetal. DCM may also be used as solvent for the synthesis of 2-bromo-6-lithiopyridine from 2,6-dibromopyridine via lithium-bromine exchange reaction. |
| General description: | Dichloromethane has been tested as a solvent medium for the dipyridine-chromium(VI) oxide. Solubility was reported to be 12.5g/100ml. Role of quantity of TiO2 loading on activated carbon support employed in the photodecomposition of dichloromethane has been investigated. |
| General description: | Dichloromethane is a chlorinated organic solvent that is susceptible to degradation with time. This can be suppressed by adding amylene as a stabilizer. |
