n-Butyl acetate, wanda kuma aka sani da Butyl acetate, wani fili ne na halitta wanda aka saba amfani dashi azaman kaushi wajen samar da lacquers da sauran kayayyakin. Ana kuma amfani da ita azaman ɗanɗanon 'ya'yan itace na roba a cikin abinci kamar alewa, ice cream, cuku, da kayan gasa. Ana samun Butyl acetate a cikin nau'ikan 'ya'yan itace da yawa, inda tare da wasu sinadarai yana ba da dandano mai ban sha'awa. apples, musamman na Red Delicious iri-iri, ana cinye su a wani ɓangare ta wannan sinadari. Ruwa ne mara launi mara launi mai kamshin ayaba.

Butyl acetate wani fili ne, mai iya ƙonewa na acetic acid wanda ke faruwa a cikin n-, sec-, da tert-forms (INCHEM, 2005). Butyl acetate isomers suna da 'ya'yan itace, wari irin na ayaba (Furia, 1980). Ana samun Isomers na butyl acetate a cikin apples (Nicholas, 1973) da sauran 'ya'yan itatuwa (Bisesi, 1994), da kuma a cikin adadin kayan abinci, irin su cuku, kofi, giya, gasasshen kwayoyi, vinegar (Maarse da Visscher, 1989). Butyl acetate ana kera shi ta hanyar esterification na barasa tare da acetic acid ko acetic anhydride (Bisesi, 1994). Ana amfani da N-butyl acetate azaman mai narkewa don lacquers na tushen nitrocellulose, tawada, da adhesives. Sauran abubuwan amfani sun haɗa da kera fata na wucin gadi, fim ɗin hoto, gilashin aminci, da robobi (Budavari, 1996). Isomers na butyl acetate kuma ana amfani da su azaman abubuwan ɗanɗano, a cikin samfuran yankan yanka, da kuma larvicides (Bisesi, 1994).

Butyl acetate ruwa ne mara launi ko rawaya tare da kamshin 'ya'yan itace. konawa sai kuma dandanon abarba mai dadi. Yana faruwa a cikin 'ya'yan itatuwa da yawa kuma shine tushen ƙamshin apples. Butyl acetate bai dace da ma'auni mai ƙarfi mai ƙarfi, acid mai ƙarfi, da tushe mai ƙarfi.
Akwai 4 isomers. A 20 ° C, girman n-butyl isomer shine 0.8825 g/cm3, kuma yawan sec-isomer shine 0.8758 g/cm3 (Bisesi, 1994). N-butyl isomer yana narkewa a cikin mafi yawan hydrocarbons da acetone, kuma yana da haɗari tare da ethanol, ethyl ether, da chloroform (Haynes, 2010). Yana narkar da robobi da resins da yawa (NIOSH, 1981).
