Application field

Technical background

Acetone is a colorless, transparent liquid with a distinctive pungent odor. Soluble in water, methanol, ethanol, ether, chloroform, pyridine and other organic solvents, flammable, volatile, more active chemical properties. Acetone is mainly used as solvent in the industries of explosives, plastics, rubber, fiber, leather, grease and spray paint, and it can also be used as an important raw material for the synthesis of enone, acetic anhydride, iodoform, polyisoprene rubber, methyl methacrylate, chloroform, epoxy resin and other materials.

Craft contrast

Taking acetone dehydration of 4000 tons/year as an example, the initial water content of acetone is 20wt.%, and the water content of acetone products is ≤0.5wt.%.
