2-Propenoic acid, 2-methyl-, tetrahydro-2-oxo-3-furanyl ester, also known as hexyl ester (Hexenal ester), is an organic compound. Its chemical formula is C7H10O3 and its molecular weight is 142.15g/mol.
Nature:
Hexyl ester is a colorless to pale yellow liquid with a special fragrance. It has a boiling point of 157-160°C and a density of about 0.99g/cm³. It is almost insoluble in water at normal temperature, but soluble in organic solvents such as alcohols and ethers.
Use:
Hexyl esters are primarily used in the food and flavor industries. It is widely used as an ingredient in fruit and strawberry spices, and can also be used in the preparation of flavors. In addition, hexyl esters can also be used as raw materials for industrial solvents and softeners.
Preparation Method:
The preparation of hexyl esters is usually carried out by an acid catalyzed reaction. A common preparation method is the reaction of 2-hexanoic acid with 2-propenal to produce 2-hexenol, which is then reacted with alcohol to produce hexyl ester by transesterification.
Safety Information:
Hexyl esters are relatively safe compounds under general conditions of use. However, as a chemical, it is still necessary to take appropriate protective measures when used. Avoid contact with skin and maintain a well-ventilated working environment. If you take it by mistake or if skin contact occurs, you should seek medical help immediately. At the same time pay attention to comply with the relevant safety procedures.
