Diacetone Alcohol

1. Product description:

Diacetone alcohol is also called 4-hydroxy-4-methyl-2-pentanone, Pyranton. Diacetone alcohol is soluble in chloroform and miscible with water, ethanol and ether. Diacetone alcohol is chemically unstable and easily decomposes under normal pressure during rectification. Diacetone alcohol is easily decomposed into acetone in alkaline solution, that is, there is a dynamic equilibrium with acetone in alkaline solution. Under milder conditions and acid action. Use Diacetone alcohol is one of the important derivatives of acetone, used to prepare metal cleaners, wood preservatives, hydraulic oil solvents; diacetone alcohol can be used to prepare methyl isobutyl ketone, methyl isobutyl methanol, hexene diacetone Intermediates of alcohol, phenyloxy, isophorone, etc.; diacetone alcohol can be used as a solvent for spray paint, celluloid, nitrocellulose, fat, grease, wax, dyes and resins; diacetone alcohol can be used as a preservative for photographic films Agents, antifreeze agents, extractants, pharmaceutical intermediates, special comonomers, raw materials for organic synthesis, etc. Preparation 1) Preparation of the catalyst The metal aluminum plate (thickness 0.1mm, purity 99.0%) is immersed in a 20% NaOH solution for 3 minutes, and then immersed in a 30% HNO3 solution for 1 minute to remove the metal Natural oxide layer on the aluminum surface. The treated aluminum plate is used as the anode, the lead plate is used as the cathode, and 4% oxalic acid is used as the electrolyte. The anode is carried out under the conditions of current density of 1.5A/dm2, temperature of 20℃, and time of 1.5h. After oxidation, the Al2O3-Al carrier was made into a Raschig ring filler form with a diameter of about 3mm, and then water-sealed in a water bath at 80°C for 1.5 hours, and then calcined at 350°C for 1 hour to form the carrier. The catalyst carrier is immersed in a certain concentration of Mg(NO3)2 solution, stirred at a certain temperature for a certain period of time and then allowed to stand for a certain period of time. After the immersion is completed, it is dried in an oven at 125°C for more than 8 hours. It is calcined at a certain temperature for a certain time to prepare a filler type MgO/Al2O3-Al solid base catalyst. 2) Acetone condensation reaction The condensation reaction is carried out in a 250mL three-necked flask. The reaction temperature is controlled with a junction thermometer, and heated and stirred with a SZCL digital temperature controlled magnetic stirrer. The catalytic reaction is carried out under boiling conditions, adding 100 mL of raw material acetone, 2 g of catalyst loading, no water agent, reaction time 1 h, the product is analyzed by a GC-14C gas chromatograph, and the acetone conversion rate is used to indicate the activity of the catalyst. The results showed that the suitable preparation conditions of the catalyst were as follows: impregnation solution concentration 2.0%, impregnation temperature 55℃, impregnation time 2.0h, calcination temperature 550℃ and calcination time 4.0h. Under these conditions, the conversion rate of acetone was 21.08%, and the selectivity of diacetone alcohol was 100%.
