[0002] Dioxolane is an organic compound, a colorless transparent liquid, soluble in water, ethanol, ether, and acetone. It is an excellent organic solvent and is often used as a solvent for oils and fats, an extractant, and an electrolytic solvent for lithium batteries. Chlorine-based solvents are stable. In the production of dioxolane, hemiacetal (synthesized by the reaction of ethylene glycol and formaldehyde) is now mostly used in the presence of a p-toluenesulfonic acid catalyst to synthesize dioxolane. The reaction is carried out at a boiling temperature of 100-110°C. During the reaction, a reactor is required for continuous synthesis and heating.
