Description |
Ethyl 2-methylbutyrate is the ethyl ester form of the 2-methylbutyrate with pleasant sweet aroma. It is a naturally occurring ester which is found in apple, wine, orange, strawberry, cheese, milk, mango, cognac, etc. It is a highly valuable flavoring agent used in flavoring in foods and beverages as well as fragrance in perfume and perfumed products. It is generally prepared through the esterification between alcohol and 2-methylbutyrate. |

Chemical Properties |
clear colorless liquid |
|
Chemical Properties |
Ethyl 2-Methylbutyrate is a liquid with a green, fruity odor reminiscent of apples. It is found, for example, in citrus fruits and wild berries and is used in fruit flavor compositions. |
|
Chemical Properties |
Ethyl 2-methylbutyrate has a powerful, green-fruity, apple-like odor. |
|
Occurrence |
Reported found in nature; the ethyl l-methylbutyrate has been identified in strawberry juice; because of the presence of the asymmetric carbon, the compound should exhibit optically active forms as well as the racemic form; however, only the d-form and the racemic form are known. Reported found in apple juice, orange and grapefruit juice, bilberry, pineapple, strawberry, cheeses, milk, cognac, rum, whiskey, cider, mango, mountain papaya, spineless monkey orange (Strychnos madagasc.), Chinese quince and German chamomile oil. |
|
Preparation |
The racemic form can be prepared catalytically by several methods: from butene and Ni(CO)4 under nitrogen in ethyl alcohol/acetic acid solution, or from ethylene and CO under pressure using HBF4 and HF as catalysts. |
