Ethyl 2-methylbutyrate Usage And Synthesis

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.
Aroma threshold values	Detection: 0.01 to 0.1 ppb
Taste threshold values	Taste characteristics at 40 ppm: fruity, green, berry, strawberry, fresh apple, pineapple and raspberry
General Description	A colorless oily liquid with a fruity odor. Insoluble in water and less dense than water. Flash point 73°F. Contact may irritate skin, eyes and mucous membranes.
