An Overview of Di Acetone Alcohol Petrochemical Solvent
Di acetone alcohol (also known as DAA, 4-hydroxy-4methyl-2-pentanone, Tyranton,billige MBT Schuhe, and diacetone) is a clear,Mbt Schuhe Flamme, colourless, liquid that is miscible with alcohols, aromatic and hydrogenated hydrocarbons,scarpe hogan, esters, and water. It has a mild odour and has the formula C6H12O2. It occurs naturally in the plant Sleepy Grass (achnatherum robustum) but is prepared synthetically for use in the chemical and industrial industries where it is used mainly as a solvent as it has one of the most favourable dilution rates of the nitrocellulose solvents,MBT Tunisha Schuhe, coupled with a relatively slow evaporation rate.
Production
Di acetone alcohol can be prepared from acetone by the action of the alkali metal hydroxides, calcium hydroxide and barium hydroxide.
Storage and distribution
Di acetone alcohol is stored in mild steel and /or stainless steel tanks and/or drums and can be transported by bulk vessels or tank trucks. It should be stored in an area that is well ventilated and that is away from sunlight, ignition sources, and other forms of heat. For transportation purposes it comes into packing group III, hazard class 3.3 and is an irritant. It has a specific gravity of 0.938 and a flash point of 59 C (closed cup).
Uses
The main use for Di acetone alcohol is as a solvent where its favourable dilution rate and relatively high evaporation rate makes it a popular choice as a solvent for water based coatings, and as a component of solvent blends for nitrocellulose,MBT Schuhe Baridi, acrylics, and cellulose acetate lacquers and thinners. DAA also helps pigment flocculation which aids in the clean up of the production and storage facilities, and of equipment.
DAA is also a component of gravure printing inks where it imparts a favourable flow and levelling characteristic to the inks. It is also used in the making of artificial silk and leather, in imitation gold leaf,hogan, and in wood stains,Mbt Schuhe Koshi, and wood preservatives. It can also be found in degreasers and metal cleaning compounds, and as a stripping aid for textiles. It is also used as a solvent for extracting impurities from resins and waxes, and as gum and resin removers in automobile carburetor cleaners.
DAA is also important as a chemical intermediate as it can be condensed to produce the unsaturated ketone mesityl oxide (MO) and water. This carbon-carbon double bond of MO is then selectively hydrogenated to produce MIBK (methyl isobutyl ketone) which is, itself, a valuable industrial solvent in both the paint, and chemical, industries.
