|Section2= |Section3= |Section7= |Section8= }} Ethyl lactate, also known as lactic acid ethyl ester, is a monobasic ester formed from lactic acid and ethanol, commonly used as a solvent. This compound is considered biodegradable and can be used as a water-rinsible degreaser. Ethyl lactate is found naturally in small quantities in a wide variety of foods including wine, chicken, and various fruits. The odor of ethyl lactate when dilute is mild, buttery, creamy, with hints of fruit and coconut. Ethyl lactate is produced from biological sources, and can be either the levo (''S'') form or dextro (''R'') form, depending on the organism that is the source of the lactic acid. Most biologically sourced ethyl lactate is ethyl (−)-L-lactate (ethyl (''S'')-lactate). Ethyl lactate is also produced industrially from petrochemical stocks, and this ethyl lactate consists of the racemic mixture of levo and dextro forms. In some jurisdictions, the ''natural'' product is exempt from many restrictions placed upon use and disposal of solvents. Because both enantiomers are found in nature, and because ethyl lactate is easily biodegradable, it is considered to be a "green solvent." Due to its relatively low toxicity, ethyl lactate is used commonly in pharmaceutical preparations, food additives,〔() U.S. Food and Drug Administration, Center for Food Safety and Applied Nutrition〕 and fragrances. Ethyl lactate is also used as solvent for nitrocellulose, cellulose acetate, and cellulose ethers.〔"Industrial Solvents Handbook" by Ernest W. Flick. 5th Edition. William Andrew Inc., 1998. ISBN 0-8155-1413-1, ISBN 978-0-8155-1413-8〕 Ethyl lactate hydrolyzes in the presence of water and acids or bases into lactic acid and ethanol. Ethyl lactate can be used as a cosolvent to produce suitable conditions for the formation of aryl aldimines. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ethyl lactate」の詳細全文を読む スポンサード リンク
