Introduction
Trans-2-undecynal is an organic compound. It is a colorless liquid with a strong botanical aromatic odor.
Trans-2-undecylenal is widely used in the fragrance and flavor industry.
A common method for the preparation of trans-2-undecylenal is obtained by heptene isomerization. The specific method is to react heptene with trifluoroacetic anhydride at low temperature, and then catalyze the hydrogenation of the product with ammonium hydroxylamine chloride to obtain trans-2-undecylenal.
The use of trans-2-undecynal should be used with caution and safety. It is irritating and may cause irritation and inflammation in contact with the skin and eyes. Direct inhalation or ingestion should be avoided during use, and care should be taken to use protective gloves, eye protection, and respirators. In case of exposure, the affected area should be immediately rinsed with plenty of water and a doctor should be consulted. During storage, trans-2-undecylenal should be stored in a cool, dry, well-ventilated place, and avoid contact with oxidants and high temperatures.
