|Section2= |Section3= }} Dehydroacetic acid is an organic compound. The compound is classified as a pyrone derivative and is used mostly as a fungicide and bactericide. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water. It is prepared by the base-catalysed dimerization of diketene.〔Raimund Miller, Claudio Abaecherli, Adel Said, Barry Jackson "Ketenes" in Ullmann's Encyclopedia of Industrial Chemistry, 2001, Wiley-VCH, Weinheim. 〕 ==Applications== Industrially, it is also used as a plasticizer in synthetic resins.〔 It is used to reduce pickle bloating as a preservative for squash and strawberries.〔''Handbook of Biocide and Preservative Use'', Harold William Rossmoore, p. 341 ISBN 0-7514-0212-5〕 Also used in antienzyme toothpastes. Clinical tests show little to no evidence regarding the ingredient's toxicity and potential for irritation.〔http://www.truthinaging.com/ingredients/dehydroacetic-acid〕 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「dehydroacetic acid」の詳細全文を読む スポンサード リンク
