| Application | diethyl dibutylmalonate can be used for the preparation of gelberylic acid. Gelbert acid, a fatty acid with a longer branched alkane at the α-position of the carboxylic acid, is colorless and tasteless compared with a straight-chain fatty acid with the same carbon number, and has almost no adverse effects on the human body, it is widely used in industrial lubricants, metal working fluids, cosmetics, surfactants and additives. |
| preparation | under the protection of nitrogen, put g of diethyl malonate and ML of anhydrous ethanol into a 1000mL three-necked round-bottomed flask at room temperature, 40.5g of sodium methoxide was added, and then 102.8G of n-butane bromide was slowly added. After the addition was completed, the reaction was heated and refluxed for 3H. After the reaction was cooled to room temperature, 40.5g of sodium methoxide was further added, and then 102.8G of n-butane bromide was slowly added, and the reaction was heated and refluxed for 3H. The temperature was cooled to room temperature, the solvent was removed, and 1mol/L sulfuric acid aqueous solution was added to neutralize the system to a pH value of about 7. The organic phase was washed with water and distilled under reduced pressure to obtain diethyl dibutyl malonate, 154g (yield 90.6%). |
| purpose | used as raw material of medicine and pesticide intermediate |
