Dichloromethane (Methylene chloride) may be used in the following processes:
• As an extractant for 2,2-dithioethyl-4-(2′-pyridyl)-4-butyro-γ-lactone.
Dichloromethane may also be used in ultrasonic baths for cleaning and protection of aluminum coating over atactic-PMMA (poly(methyl methacrylate)) for dielectric studies
