Uses

Used in the production of metal cleaners, wood preservatives, preservatives for photographic film and pharmaceuticals, antifreeze, hydraulic oil solvents, extractants, and fiber finishing agents;

Widely used as a solvent for electrostatic spraying, celluloid, nitrocellulose, fats, oils, waxes, and resins;

Diacetone alcohol is a high-boiling-point organic solvent. It has low viscosity, and temperature has little effect on viscosity. Used as a solvent and paint remover for cellulose ester paints, printing inks, and synthetic resin coatings;

Diacetone alcohol is an intermediate in the production of isopropyl acetone, methyl isobutyl ketone, methyl isobutyl methanol, hexanediol, phorone, and isophorone from acetone;

Used as a high-boiling-point solvent in cosmetics such as nail polish. It is usually formulated into mixed solvents with low-boiling-point and medium-boiling-point solvents to obtain suitable evaporation rates and viscosities.
