The invention discloses a production method of trans-2.4-nonadienal. The invention adopts n-valeraldehyde, ethanol and vinyl ether as main raw materials, acetic acid as solvent and calcium chloride as water absorbing agent, and the reaction is carried out in a closed reaction Quantitative reaction in the kettle, through the synthesis of 1.1-diethoxypentane, the synthesis of 1.1.3-triethoxyheptane, the synthesis of 1.1.3.5-tetraethoxynonane, the final hydrolysis generates trans-2.4- Nonadienal. After repeated tests, trial production and production, good results are obtained; the product yield and quality are high, and the highest yield can reach 30%. The invention has the advantages of simple operation, safety and environmental protection, and is suitable for large-scale industrial production. |
