Information @ a Glance

General

  • Diacetone alcohol is a chemical compound with the formula CH3C(O)CH2C(OH)(CH3)2.
  • This liquid is common synthetic intermediate used for the preparation of other compounds.
  • Diacetone alcohol has slow evaporation rates. It is used as a solvent for both hydrogen bonding and polar substances.
  • It is miscible in water and used as a solvent for water-based coatings.

Process

  • Diacetone alcohol can be prepared from acetone by the action of alkali metal hydroxides, calcium hydroxide, and barium hydroxide.
  • Methyl isobutyl ketone (MIBK) is a valuable industrial solvent produced commercially in a three-stage process from an acetone feedstock. First, acetone is dimerized to produce diacetone alcohol (DAA). Second, DAA undergoes a condensation reaction to produce mesityl oxide (MO) and water. Third, the carbon-carbon double bond of MO is selectively hydrogenated to produce MIBK.

Uses

  • It is used as a solvent extractant in purification processes for resins and waxes.
  • Diacetone alcohol is more suitable for use in applications as a component of gravure printing inks, with proving favorable flow and leveling characteristics.
  • Diacetone alcohol, having hydroxyl and carbonyl group in the same molecule is used as a chemical intermediate.

Report

  • The production volume of diacetone alcohol in Japan is 3,236 tonnes/year in past years.
  • A report from a Japanese manufacturer, 147 kg/year measured of diacetone alcohol are treated in its own wastewater treatment plant with 85% of removal rate and are released with 3.6 x 1010 L/year of effluent into river.
