| titleOfInvention | Method for obtaining benzaldehydes |
| abstract | The invention relates to the production of aldehydes, in particular the production of p-methyl (ilm methox of benzaldehydes used as components of fragrances, fragrances and food flavors or in the synthesis of pesticides. The purpose of the invention is to increase the yield of the target product. For this, electrochemical oxidation of n-propenyltoluene is carried out or p-propanilanisole in a diaphragm-free electrolyzer equipped with a graphite anode and cathode (preferably with low, medium and high hydrogen overvoltage) in the presence of a background electrolyte salt of a halogen-substituted aliphatic carboxylic acid or sulfonic acid (preferably the Na or K-salts of trifluoroacetic or toluenesulfonic acid). At the same time, n-propenylanisole (or toluene) is gradually introduced into the electrolyzer to maintain its concentration of 0.01-0.45. mol / l, 4-4.5 F of electricity is passed through, when heated to 55-BO & C and a current density of 50-200 mA / cm2. Then, the resulting benzaldehyde dimethyl acetal is hydrolyzed. These conditions increase the yield of the target product from 51.9 to 90%. 2 hp ff. 2 tab. |
