Na Waiwai Kemika:

ʻO n-Butyl acetate, i kapa ʻia ʻo Butyl acetate, he mea hoʻohui i hoʻohana mau ʻia e like me ka solvent i ka hana ʻana i nā lacquers a me nā huahana ʻē aʻe. Hoʻohana ʻia ʻo ia ma ke ʻano he mea ʻono hua synthetic i nā meaʻai e like me ka candy, ice cream, cheeses, a me nā meaʻai i kālua ʻia. Loaʻa ka Butyl acetate i nā ʻano hua he nui, kahi me nā mea kemika ʻē aʻe e hāʻawi ai i nā ʻono ʻano. ʻO nā ʻāpala, ʻoi aku ka nui o nā ʻano ʻano Red Delicious, ua hoʻonani ʻia i kekahi hapa e kēia kemika. He wai lapalapa ʻole me ka ʻala ʻono o ka maiʻa.

ʻO ka butyl acetate kahi ester akaka a hiki ke puhi ʻia o ka ʻakika acetic i loaʻa i nā ʻano n-, sec-, a me nā ʻano ʻano (INCHEM, 2005). Loaʻa i nā isomers Butyl acetate kahi ʻala hua, like me ka maiʻa (Furia, 1980). Loaʻa nā isomers o ka butyl acetate i nā ʻāpala (Nicholas, 1973) a me nā huaʻai ʻē aʻe (Bisesi, 1994), a me nā huahana meaʻai he nui, e like me ka cheese, kofe, pia, nā nati i kālua ʻia, ka vīnega (Maarse a me Visscher, 1989). Hana ʻia ka Butyl acetate ma o ka esterification o kēlā me kēia ʻona me ka acetic acid a i ʻole acetic anhydride (Bisesi, 1994). Hoʻohana ʻia ka N-butyl acetate ma ke ʻano he mea hoʻoheheʻe no nā lacquers e pili ana i ka nitrocellulose, inks, a me nā mea hoʻopili. ʻO nā mea hoʻohana ʻē aʻe ka hana ʻana i nā ʻili ʻili, ke kiʻiʻoniʻoni, ke aniani palekana, a me nā plastics (Budavari, 1996). Hoʻohana pū ʻia nā isomers o ka butyl acetate ma ke ʻano he mea ʻono, i nā huahana manicure, a me nā larvicides (Bisesi, 1994). Ua hoʻohana ʻia ka tert-isomer ma ke ʻano he ʻaila hoʻohui (Budavari, 1996). Hiki ke hoʻohana ʻia ma ke ʻano he mea ʻono hua synthetic i loko o ka candy, ice cream, cheeses, a me nā mea i kālua ʻia (Dikshith, 2013).

ʻO ka Butyl acetate he wai kala ʻole a melemele paha me ka ʻala hua ikaika. ʻā a laila ʻono ʻono e hoʻomanaʻo ana i ka pineapple. Loaʻa ia i nā hua he nui a he mea hoʻohui o nā ʻala ʻala. ʻAʻole kūpono ʻo Butyl acetate me nā mea hoʻoheheʻe ikaika, nā waikawa ikaika, a me nā kumu ikaika.
He 4 isomer. Ma 20 °C, he 0.8825 g/cm3 ka mānoanoa o ka isomer n-butyl, a he 0.8758 g/cm3 ka mānoanoa o ka isomer sec (Bisesi, 1994). Hiki ke hoʻoheheʻe ʻia ka isomer n-butyl i loko o ka hapa nui o ka hydrocarbons a me ka acetone, a hiki ke hui pū me ka ethanol, ethyl ether, a me ka chloroform (Haynes, 2010). Hoʻoheheʻe ia i nā plastics a me nā resins (NIOSH, 1981).

ʻO ka wai akaka, ʻaʻohe waihoʻoluʻu me ka ʻala hua ikaika e like me ka maiʻa. ʻO ka ʻono ʻono e like me nā haʻahaʻa haʻahaʻa (<30 μg/L). ʻO 30 μg/m3 (6.3 ppbv) a me 18 μg/m3 (38 ppbv) i hoʻoholo ʻia i hoʻokolohua ʻia, ʻo ia hoʻi (Hellman and Small, 1974). Cometto-Mu?iz et al. (2000) hōʻike i ka nasal pungency threshold concentrations mai kahi o 550 a 3,500 ppm.

Noi:

1, ma ke ʻano he mea ʻala, ka nui o nā maiʻa, nā pears, nā pineapples, nā apricots, nā peach a me nā strawberries, nā hua a me nā ʻano ʻono ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he solvent no ka gum maoli a me ka resin synthetic, etc.

2、Excellent organic solvent, me ka solubility maikaʻi no cellulose acetate butyrate, ethyl cellulose, chlorinated rubber, polystyrene, methacrylic resin a me nā resins maoli e like me ka tannin, manila gum, dammar resin, etc. solvent i ke kaʻina hana o ka ʻili artificial, ka lole a me ka hana plastik, i hoʻohana ʻia ma ke ʻano he extractant i nā ʻano hana ʻaila a me ka hana lāʻau lapaʻau, hoʻohana pū ʻia i ka hui ʻana i nā mea ʻala a me nā ʻāpana like ʻole o ka apricot, ka maiʻa, ka pear, ka pineapple a me nā mea ʻala ʻē aʻe.
3、Hoʻohana ʻia ma ke ʻano he analytical reagents, chromatographic analysis standards a me nā solvents.
