Chemical Properties:

n-Butyl acetate, inozivikanwawo seButyl acetate, inhengo yehupenyu inowanzoshandiswa sechinhu chinonyungudutsa mukugadzirwa kwe lacquers nezvimwe zvigadzirwa. Inoshandiswawo seyakagadzirwa michero inonhuwira muzvikafu zvakaita sesiwiti, ice cream, cheeses, uye zvinhu zvakabikwa. Butyl acetate inowanikwa mumhando dzakawanda dzemichero, apo pamwe chete nemamwe makemikari inopa maitiro ekunaka. maapuro, kunyanya eRed Delicious akasiyana, anotorwa muchikamu nekemikari iyi. Imvura inopfuta isina ruvara ine kunhuhwirira kwakanaka kwebhanana.

Butyl acetate yakajeka, inopisa ester yeacetic acid inowanikwa mu n-, sec-, uye tert-forms (INCHEM, 2005). Butyl acetate isomers ine muchero, kunhuhwirira kwebhanana (Furia, 1980). Isomers yebutyl acetate inowanikwa mumaapuro (Nicholas, 1973) nemimwe michero (Bisesi, 1994), pamwe chete nenhamba yezvigadzirwa zvekudya, senge chizi, kofi, doro, nzungu dzakakangwa, vhiniga (Maarse uye Visscher, 1989). Butyl acetate inogadzirwa kuburikidza ne esterification yedoro rakasiyana neacetic acid kana acetic anhydride (Bisesi, 1994). N-butyl acetate inoshandiswa se solvent ye nitrocellulose-based lacquers, ingi, uye zvinonamira. Zvimwe zvinoshandiswa zvinosanganisira kugadzirwa kwematehwe ekugadzira, firimu remifananidzo, girazi rekuchengetedza, uye mapurasitiki (Budavari, 1996). Isomers yebutyl acetate inoshandiswawo seanonhuhwirira, mune manicure zvigadzirwa, uye selarvicides (Bisesi, 1994). Iyo tert-isomer yakashandiswa sekuwedzera peturu (Budavari, 1996). Inogona kushandiswa seyakagadzirwa michero inonhuwira mu candy, ice cream, cheeses, uye zvakabikwa zvinhu (Dikshith, 2013).

Butyl acetate imvura isina ruvara kana yero ine kunhuhwirira kwakasimba kwemuchero. kusvirwa uyezve kutapira kuravira kuyeuchidza pineapple. Inowanikwa mumichero yakawanda uye inhengo yeapuro inonhuhwirira. Butyl acetate haienderani neakasimba oxidizing agents, yakasimba acids, uye mabhesi akasimba.
Kune 4 isomers. Pa20 °C, kuwanda kwen-butyl isomer ndeye 0.8825 g/ cm3, uye density ye sec-isomer ndeye 0.8758 g/cm3 (Bisesi, 1994). Iyo n-butyl isomer inonyungudika mumahydrocarbon mazhinji uye acetone, uye inosanganiswa ne ethanol, ethyl ether, uye chloroform (Haynes, 2010). Inonyungudutsa mapurasitiki akawanda uye resin (NIOSH, 1981).

Mvura yakachena, isina ruvara ine muchero wakasimba hwemabhanana. Kuravira kunotapira sekudzika kwakadzika (<30 μg/L). Kuongororwa kwakatemwa kucherechedzwa uye kucherechedzwa kunhuhwirira kwechikumbaridzo chaive 30 μg/m3 (6.3 ppbv) uye 18 μg/m3 (38 ppbv), zvichiteerana (Hellman uye Diki, 1974). Cometto-Mu?iz et al. (2000) yakashumwa nasal pungency threshold concentrations kubva pa550 kusvika 3,500 ppm.

Application:

1, se spice, nhamba huru yemabhanana, mapeya, mapineapples, maapricots, mapichisi uye sitirobheri, mabheri uye mamwe marudzi ekunaka. Inogona zvakare kushandiswa sechinhu chinonyungudutsa chegamu uye synthetic resin, nezvimwe.

2, Yakanakisa organic solvent, ine yakanaka solubility ye cellulose acetate butyrate, ethyl cellulose, chlorinated rabha, polystyrene, methacrylic resin uye akawanda maresin echisikigo akadai setannin, manila gum, dammar resin, etc. Inoshandiswa zvakanyanya mu nitrocellulose varnish, inoshandiswa se solvent mukugadzira dehwe rekugadzira, machira uye epurasitiki kugadzirisa, inoshandiswa seyakasiyana-siyana petroleum processing uye pharmaceutical process, inoshandiswawo mukubatanidza zvinonhuwira uye zvakasiyana-siyana zveapricot, bhanana, pear, pineapple uye zvimwe zvinonhuhwirira.
3, Inoshandiswa seanalytical reagents, chromatographic yekuongorora zviyero uye zvinonyungudutsa.
