- Molecular formula:C5H7NO
- Molecular Weight:97.12
Yield:3350-74-1 97.7%
Reaction Conditions:
with tetramethyl ammoniumhydroxide at 30 - 150; for 3 h;
Steps:
2.1 (1). Preparation of 5-oxovaleronitrile
434.8 g (10.5 mol, 99%) of acetonitrile was placed in a 2500 ml four-necked flask. Raise the temperature to reflux temperature, Then, 36.44 g (0.1 mol, 25%) tetramethylammonium hydroxide solution was added dropwise using a dropping funnel. 566.0 g acrolein (10.0 mol, 99%), The drop time is 2h. Keep the reaction temperature at the reflux temperature, After the feed is complete, continue the reaction for 1h, Obtained 1029.46 g of reaction solution. Product purification is the same as in Example 1, Product 955.33g with a purity of 99.2% was obtained. The final product yielded 97.70% as acrolein.
