Methyl acetate, also known as MeOAc , acetic acid methyl ester or methyl ethanoate, is a carboxylate ester with the formula CH3COOCH3. Acetic acid, methyl ester is a flammable liquid with a characteristically pleasant smell reminiscent of some glues and nail polish removers. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or aqueous acids. Methyl acetate is VOC exempt. Reported found in apple, banana, sweet and sour cherry, tangerine juice, black currants, guava, grapes, melon, peach, pear, pineapple, strawberry, cabbage, tomato, clove bud, peppermint oil, vinegar, bread, cheeses, butter, yogurt, beef, beer, cognac, rum, whiskies, cider, sherry, grape wines, cocoa, coffee, filbert, peanut, honey, soybean, olive, passion fruit, fruit brandies, fig, gin, kiwifruit, clary sage, arrack and nectarine. Methyl acetate is used as a solvent forlacquers, resins, oils, and nitrocellulose; inpaint removers; as a flavoring agent; and inthe manufacture of artificial leather.
