Lintho tsa Lik'hemik'hale:

n-Butyl acetate, eo hape e tsejoang e le Butyl acetate, ke motsoako oa tlhaho o atisang ho sebelisoa e le mokelikeli ha ho etsoa li-lacquers le lihlahisoa tse ling. E boetse e sebelisoa e le tatso ea litholoana tse entsoeng lijong tse kang lipompong, ice cream, lichisi le lintho tse besitsoeng. Butyl acetate e fumanoa mefuteng e mengata ea litholoana, moo hammoho le lik'hemik'hale tse ling e fanang ka tatso e ikhethang. liapole, haholo-holo tsa mefuta e fapaneng ea Red Delicious, li na le karolo e 'ngoe ea lik'hemik'hale tsena. Ke mokelikeli o se nang 'mala o tukang le monko o monate oa banana.

Butyl acetate ke ester e hlakileng, e tukang ea acetic acid e hlahang ka n-, sec-, le tert-forms (INCHEM, 2005). Li-isomers tsa butyl acetate li na le monko o monate, o kang oa banana (Furia, 1980). Li-isomers tsa butyl acetate li fumanoa liapole (Nicholas, 1973) le litholoana tse ling (Bisesi, 1994), hammoho le lihlahisoa tse ngata tsa lijo, tse kang chisi, kofi, biri, linate tse halikiloeng, asene (Maarse le Visscher, 1989). Butyl acetate e etsoa ka esterification ea joala bo fapaneng ka acetic acid kapa acetic anhydride (Bisesi, 1994). N-butyl acetate e sebelisoa e le solvent bakeng sa li-lacquers tse thehiloeng ho nitrocellulose, li-inks le li-adhesives. Lisebelisoa tse ling li kenyelletsa ho etsa matlalo a maiketsetso, filimi ea lifoto, likhalase tsa polokeho le polasetiki (Budavari, 1996). Li-isomers tsa butyl acetate li boetse li sebelisoa e le litlolo tsa tatso, lihlahisoa tsa manicure, le li-larvicides (Bisesi, 1994). tert-isomer e sebelisitsoe joalo ka tlatsetso ea peterole (Budavari, 1996). E ka sebelisoa e le tatso ea litholoana tse entsoeng ka lipompong, ice cream, chisi le lintho tse halikiloeng (Dikshith, 2013).

Butyl acetate ke mokelikeli o se nang 'mala kapa o mosehla o nang le monko o matla oa litholoana. ho chesa ebe tatso e monate e hopotsang phaenapole. E hlaha litholoana tse ngata 'me ke motsoako oa monko oa liapole. Butyl acetate ha e tsamaellane le li-oxidizing agents tse matla, li-acid tse matla, le metheo e matla.
Ho na le li-isomers tse 4. Ho 20 °C, boima ba isomere ea n-butyl ke 0.8825 g/ cm3, 'me letsoalo la sec-isomer ke 0.8758 g/cm3 (Bisesi, 1994). N-butyl isomer e qhibiliha ka har'a hydrocarbons le acetone, 'me e tsoakana le ethanol, ethyl ether, le chloroform (Haynes, 2010). E qhaqha li-plastiki le li-resin tse ngata (NIOSH, 1981).

Mokelikeli o hlakileng, o se nang 'mala o nang le monko o matla oa litholoana o kang oa libanana. Tatso e monate joalo ka likhakanyo tse tlase (<30 μg/L). Teko e entsoeng ho lemoha le ho lemoha monko o monate e ne e le 30 μg/m3 (6.3 ppbv) le 18 μg/m3 (38 ppbv), ka ho latellana (Hellman and Small, 1974). Cometto-Mu?iz et al. (2000) e tlalehiloeng hore nasal pungency threshold concentrations e tloha ho hoo e ka bang 550 ho isa ho 3,500 ppm.

Kopo:

1, joalo ka linoko, palo e kholo ea libanana, lipere, liphaenapole, liapolekose, liperekisi le fragole, monokotsoai le mefuta e meng ea litatso. E ka boela ea sebelisoa e le solvent bakeng sa chese ea tlhaho le resin ea maiketsetso, joalo-joalo.

2, Excellent organic solvent, e nang le solubility e ntle bakeng sa selulose acetate butyrate, ethyl cellulose, rabara e chlorinated, polystyrene, methacrylic resin le li-resin tse ngata tsa tlhaho tse kang tannin, manila gum, dammar resin, joalo-joalo E sebelisoa haholo ka varnish ea nitrocellulose, e sebelisoang e le solvent ts'ebetsong ea letlalo la maiketsetso, lesela le ts'ebetso ea polasetiki, e sebelisoang e le extractant ka mefuta e fapaneng Phekolo ea peterole le ts'ebetso ea meriana, e boetse e sebelisoa ho kopanya linoko le likarolo tse fapaneng tsa apricot, banana, pere, phaenapole le lisebelisoa tse ling tse nkhang hamonate.
