What is Diacetone Alcohol?

Diacetone alcohol is also called 4-hydroxy-4-methyl-2-pentanone, Pyranton. Diacetone alcohol is soluble in chloroform and also is miscible with water, ethanol as well as ether. Diacetone alcohol is chemically unsteady and also easily decayed by correction under normal pressure. Diacetone alcohol is conveniently decayed into acetone in alkaline remedy, that is, there is a dynamic equilibrium with acetone in alkaline option. Show acid under milder problems. Diacetone alcohol is among the essential by-products of acetone, made use of to prepare steel cleaners, wood chemicals, hydraulic oil solvents; diacetone alcohol can be utilized to prepare methyl isobutyl ketone, methyl isobutyl methanol, hexenediol, intermediates of phenyl oxide, isophorone, and so on; diacetone alcohol can be made use of as a solvent for spray paint, celluloid, nitrocellulose, fat, grease, wax, color as well as material; diacetone alcohol can be used as an image movie preservative, antifreeze, extractant, pharmaceutical intermediates, special comonomers, natural synthesis basic materials, and so on.

Preparation of Diacetone Alcohol

1) Preparation of catalyst
The metal aluminum plate (thickness of 0.1mm, purity of 99.0%) was immersed in NaOH solution with a mass fraction of 20% for 3 minutes, and then immersed in a HNO3 solution with a volume fraction of 30% for 1 minute to remove the natural oxide layer on the surface of metal aluminum. The treated aluminum plate was used as the anode, the lead plate was used as the cathode, and the oxalic acid with a mass fraction of 4% was used as the electrolyte. , the Al2O3-Al carrier was made into the form of Raschig ring packing with a diameter of about 3mm, and after being water-sealed in a water bath at 80°C for 1.5h, the carrier was calcined at 350°C for 1h. The catalyst carrier was immersed in a certain concentration of Mg(NO3)2 solution, stirred at a certain temperature for a certain period of time and then left to stand for a certain period of time. After the impregnation was completed, it was dried in an oven at 125 °C for more than 8 hours. The filler-type MgO/Al2O3-Al solid base catalyst is prepared by roasting at a certain temperature for a certain period of time.

2) Acetone condensation reaction
The condensation reaction was carried out in a 250mL three-necked flask, the reaction temperature was controlled with a junction thermometer, and heated and stirred with a SZCL type digital temperature-controlled magnetic stirrer. The catalytic reaction was carried out under boiling conditions, 100 mL of raw material acetone was added, the catalyst loading was 2 g, no water agent was added, and the reaction time was 1 h. The results show that the suitable preparation conditions of the catalyst are as follows: the concentration of impregnation solution is 2.0%, the impregnation temperature is 55℃, the impregnation time is 2.0h, and the roasting temperature is 550℃ and the roasting time is 4.0h. Under this condition, the conversion of acetone was 21.08%, and the selectivity of diacetone alcohol was 100%.

Diacetone Alcohol Application

CN201110198876.8 discloses a production process for synthesizing isohexanediol by hydrogenation reduction of diacetone alcohol, which belongs to the technical field of production technology of isohexylenediol. In the present invention, diacetone alcohol is used as a raw material, and after mixing with an auxiliary agent, under the action of a nickel-based catalyst, hydrogen is introduced under pressure to reduce and replace to synthesize ishexylene glycol; the auxiliary agent is a basic compound, as long as the hydrogenation reaction is not malignant Both basic inorganic compounds and basic organic compounds can be affected. The addition of auxiliary agents overcomes the disadvantages of low product yield, many other by-products, high production cost, difficult operation, and difficulty in product separation in the traditional process, and reduces the production of other by-products in the reduction process, thereby improving the efficiency of the reduction process. The product yield of isohexanediol synthesis, the purity of isohexanediol can reach 99.5%, and the mass yield is increased to 99%.
