Chemical Properties:

n-Butyl acetate, yomwe imadziwikanso kuti Butyl acetate, ndi organic pawiri yomwe imagwiritsidwa ntchito ngati zosungunulira popanga lacquers ndi zinthu zina. Amagwiritsidwanso ntchito ngati zokometsera zopangira zipatso muzakudya monga maswiti, ayisikilimu, tchizi, ndi zinthu zophika. Butyl acetate imapezeka mumitundu yambiri ya zipatso, komwe pamodzi ndi mankhwala ena amapereka kukoma kwapadera. maapulo, makamaka amtundu wa Red Delicious, amaphatikizidwa ndi mankhwala awa. Ndi madzi oyaka opanda mtundu okhala ndi fungo lokoma la nthochi.

Butyl acetate ndi ester yowoneka bwino, yoyaka moto ya acetic acid yomwe imapezeka mu n-, sec-, ndi tertforms (INCHEM, 2005). Ma isomers a Butyl acetate ali ndi fungo la zipatso, ngati nthochi (Furia, 1980). Ma Isomers a butyl acetate amapezeka mu maapulo (Nicholas, 1973) ndi zipatso zina (Bisesi, 1994), komanso muzakudya zingapo, monga tchizi, khofi, mowa, mtedza wokazinga, viniga (Maarse ndi Visscher), 1989). Butyl acetate imapangidwa kudzera mu esterification ya mowa womwewo ndi acetic acid kapena acetic anhydride (Bisesi, 1994). N-butyl acetate imagwiritsidwa ntchito ngati chosungunulira cha nitrocellulose-based lacquers, inki, ndi zomatira. Ntchito zina zimaphatikizapo kupanga zikopa zopangira, filimu yojambula zithunzi, galasi lachitetezo, ndi mapulasitiki (Budavari, 1996). Ma Isomers a butyl acetate amagwiritsidwanso ntchito ngati zokometsera, muzopangira za manicure, komanso ngati ma larvicides (Bisesi, 1994). The tert-isomer yagwiritsidwa ntchito ngati chowonjezera mafuta (Budavari, 1996). Itha kugwiritsidwa ntchito ngati chokometsera zipatso mu maswiti, ayisikilimu, tchizi, ndi zinthu zophika (Dikshith, 2013).

Butyl acetate ndi madzi opanda mtundu kapena achikasu okhala ndi fungo lamphamvu la zipatso. kuyaka kenako kukoma kokoma amatikumbutsa chinanazi. Amapezeka mu zipatso zambiri ndipo ndi gawo la fungo la maapulo. Butyl acetate sigwirizana ndi ma oxidizing amphamvu, ma asidi amphamvu, ndi maziko amphamvu.
Pali ma isomers 4. Pa 20 ° C, kachulukidwe ka n-butyl isomer ndi 0.8825 g/ cm3, ndipo kachulukidwe ka sec-isomer ndi 0.8758 g/cm3 (Bisesi, 1994). N-butyl isomer imasungunuka mu ma hydrocarboni ambiri ndi acetone, ndipo imasakanikirana ndi ethanol, ethyl ether, ndi chloroform (Haynes, 2010). Imasungunula mapulasitiki ambiri ndi utomoni (NIOSH, 1981).

Madzi owoneka bwino, opanda mtundu okhala ndi fungo lamphamvu la zipatso ngati nthochi. Kukoma kokoma ngati ndende zotsika (<30 μg/L). Kuzindikira koyesedwa moyeserera ndi kuzindikira fungo la fungo linali 30 μg/m3 (6.3 ppbv) ndi 18 μg/m3 (38 ppbv), motsatana (Hellman ndi Small, 1974). Cometto-Mu?iz et al. (2000) idanenanso kuti kuchuluka kwa mphuno kumayambira pafupifupi 550 mpaka 3,500 ppm.

Ntchito:

1, monga zonunkhira, nthochi zambiri, mapeyala, chinanazi, ma apricots, mapichesi ndi sitiroberi, zipatso ndi mitundu ina ya oonetsera. Itha kugwiritsidwanso ntchito ngati chosungunulira cha chingamu chachilengedwe ndi utomoni wopangira, etc.

2, Zabwino zosungunulira organic, ndi solubility wabwino kwa mapadi acetate butyrate, ethyl mapadi, mphira chlorinated, polystyrene, methacrylic utomoni ndi utomoni zambiri zachilengedwe monga tannin, manila chingamu, dammar utomoni, etc. Amagwiritsidwa ntchito mu varnish nitrocellulose, ntchito ngati zosungunulira m'kati yokumba chikopa, nsalu ndi pulasitiki processing, ntchito ngati extractant zosiyanasiyana mafuta opangira mafuta ndi njira zamankhwala, amagwiritsidwanso ntchito popanga zonunkhira ndi zigawo zosiyanasiyana za ma apricot, nthochi, peyala, chinanazi ndi zina zonunkhira.
3, Amagwiritsidwa ntchito ngati ma reagents owunikira, miyezo yowunikira ma chromatographic ndi zosungunulira.
