개요
2-Methylbutyric acid has a pungent, acrid odor similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. May be prepared by decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil).화학적 성질
clear colorless to pale yellowish liquid출처
Occurring as the d-, l-, and dl-isomers; the racemic form has been reported found in angelica root oil and coffee; the d-isomer in the ester form has been identified in lavender oil. Also reported found in apple, apricot, berries, grapes, papaya, peach, guava, pineapple, potato, bell pepper, tomato, peppermint and spearmint oil, vinegar, wheat breads, cheeses, chicken, mutton, pork, hop oil, beer, cognac, rum, whiskies, cider, cocoa, coffee, tea, peanuts, passion fruit, trassi, mango, plum, tamarind, rice, corn oil, loquat, scallops, Chinese quince, maté, mammee apple and Roman chamomile oil, cranberry, grape brandy, oriental tobacco, and strawberry제조 방법
By decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil).정의
