It is mainly used as a chemical intermediate in the production of a wide variety of compounds, such as amino acids, analgesics, antibiotics, antimalarial agents, antipyrine and aminopyrine, and vitamin B1; as well as the manufacture of dyes, inks, lacquers, perfumes, plastics, and yellow paint pigments. Alone, it is used as a flavoring for food. ==Preparation== Ethyl acetoacetate is produced industrially by treatment of diketene with ethanol.〔Wilhelm Riemenschneider and Hermann M. Bolt "Esters, Organic" Ullmann's Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. 〕 The preparation of ethyl acetoacetate is a classic laboratory procedure. It is prepared via the Claisen condensation of ethyl acetate. Two moles of ethyl acetate condense to form one mole each of ethyl acetoacetate and ethanol. : 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 acetoacetate」の詳細全文を読む スポンサード リンク
