설명

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.

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.

Application

Dichloromethane has been used for the quantification of herbivore (gypsy moth) induced blueberry volatiles by gas chromatography (GC).

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.
