Chemical Properties:

I-n-Butyl acetate, eyaziwa nangokuthi i-Butyl acetate, iyinhlanganisela yemvelo evame ukusetshenziswa njenge-solvent ekukhiqizeni ama-lacquers neminye imikhiqizo.Ibuye isetshenziswe njengesinongo sesithelo sokwenziwa ekudleni okufana noswidi, u-ayisikhilimu, ushizi, nezinto ezibhakwayo.I-butyl acetate itholakala ezinhlotsheni eziningi zesithelo, lapho kanye namanye amakhemikhali idlulisela ukunambitheka kwesici.ama-apula, ikakhulukazi ezinhlobonhlobo ze-Red Delicious, atholakala engxenyeni yaleli khemikhali.Iwuketshezi olungenambala oluvuthayo olunephunga elimnandi likabhanana.

I-Butyl acetate iyi-ester ecacile, evuthayo ye-acetic acid eyenzeka ku-n-, sec-, kanye ne-tert-forms (INCHEM, 2005).I-butyl acetate isomers inephunga elimnandi, elifana nelikabhanana (Furia, 1980).Ama-isomer e-butyl acetate atholakala kuma-apula (Nicholas, 1973) nakwezinye izithelo (Bisesi, 1994), kanye nasemikhiqizweni yokudla eminingana, njengoshizi, ikhofi, ubhiya, amantongomane athosiwe, uviniga (i-Maarse ne-Visscher, 1989).I-Butyl acetate ikhiqizwa nge-esterification yotshwala obufanele nge-acetic acid noma i-acetic anhydride (Bisesi, 1994).I-N-butyl acetate isetshenziswa njengesixazululi se-nitrocellulose-based lacquers, oyinki, nezinamatheliso.Okunye ukusetshenziswa kufaka ukwakhiwa kwezikhumba zokwenziwa, ifilimu yezithombe, ingilazi yokuphepha, namapulasitiki (Budavari, 1996).Ama-isomer e-butyl acetate nawo asetshenziswa njengama-ejenti anambitheka, emikhiqizweni ye-manicure, nanjenge-larvicides (Bisesi, 1994).I-tert-isomer isetshenziswe njengesengezo sikaphethiloli (Budavari, 1996).Ingase isetshenziswe njengesinongo sezithelo zokwenziwa kuswidi, u-ayisikhilimu, ushizi, nezinto ezibhakwayo (Dikshith, 2013).

I-Butyl acetate iwuketshezi olungenambala noma oluphuzi olunephunga elinamandla lezithelo.ukuvutha bese kuba ukunambitheka okumnandi okusikhumbuza uphayinaphu.Kuvela ezithelweni eziningi futhi kuyingxenye yamaphunga a-apula.I-Butyl acetate ayihambisani nama-oxidizing agents aqinile, ama-asidi aqinile, nezisekelo eziqinile.
Kukhona ama-isomers angu-4.Ku-20 °C, ukuminyana kwe-n-butyl isomer ngu-0.8825 g/ cm3, futhi ukuminyana kwe-sec-isomer ngu-0.8758 g/cm3 (Bisesi, 1994).I-n-butyl isomer iyancibilika kuma-hydrocarbons amaningi ne-acetone, futhi ixubana ne-ethanol, i-ethyl ether, ne-chloroform (Haynes, 2010).Incibilikisa amapulasitiki amaningi nama-resin (NIOSH, 1981).

Uketshezi olucacile, olungenambala olunephunga elinamandla lezithelo ezifana nobhanana.Ukunambitheka okumnandi njengokugxila okuphansi (<30 μg/L).Ukutholwa okunqunywe ngokuhlolwa nokuqashelwa komkhawulo wephunga bekungu-30 μg/m3 (6.3 ppbv) no-18 μg/m3 (38 ppbv), ngokulandelanayo (Hellman and Small, 1974).U-Cometto-Mu?iz et al.(2000) kubikwe ukuthi i-nasal pungency threshold concentrations isukela cishe ku-550 kuya ku-3,500 ppm.

Isicelo:

1, njengesinongo, inani elikhulu likabhanana, amapheya, uphayinaphu, amabhilikosi, amapentshisi namasitrobheni, amajikijolo nezinye izinhlobo zokunambitheka.Ingasetshenziswa futhi njenge-solvent ye-gum yemvelo kanye ne-synthetic resin, njll.

2, I-solvent ephilayo enhle kakhulu, ene-solubility enhle ye-cellulose acetate butyrate, i-ethyl cellulose, irabha e-chlorinated, i-polystyrene, i-methacrylic resin kanye nezinsalela eziningi zemvelo ezifana ne-tannin, i-manila gum, i-dammar resin, njll. Isetshenziswa kabanzi ku-nitrocellulose varnish, esetshenziswa njenge i-solvent in the process of artificial skin, fabric and plastic processing, esetshenziswa njenge-extractant ezinhlobonhlobo ze-petroleum processing kanye nenqubo yezemithi, futhi isetshenziselwa ukuhlanganiswa kwezinongo kanye nezingxenye ezihlukahlukene zebhilikosi, ubhanana, i-pear, uphayinaphu namanye ama-agent agents.
3, Isetshenziswa njengama-reagents okuhlaziya, amazinga okuhlaziya ama-chromatographic kanye nezincibilikisi.
