I-N-Butyl Acetate, eyaziwa nangokuthi i-Buthyl Acetate, iyindawo ehlanganisiwe esetshenziswa kakhulu njenge-solvent ekukhiqizweni kwama-lacquers neminye imikhiqizo. Iphinde isetshenziswe njenge-software yezithelo flavour ekudleni okufana namaswidi, u-ayisikhilimu, ushizi, nezimpahla ezibhakiwe. I-Butyl Acetate itholakala ezinhlotsheni eziningi zezithelo, lapho kanye namanye amakhemikhali anikeza ukunambitheka kwezimpawu. Ama-apula, ikakhulukazi ezinhlobonhlobo ezibomvu, avunyelwa yingxenye ngalelikhemikhali. Uketshezi olungenakuvutha olungenamibala ngephunga elimnandi lebhanana.

I-Butyl Acetate iyi-ester ecacile, evuthayo ye-acetic acid eyenzeka kuma-n-, sec- amafomu- amafomu (i-ichem, 2005). I-Buthy Acetate Isomers inesifuba, i-banana-likephunga (furia, 1980). Ama-isomers we-butyl acetate atholakala kuma-apula (nicholas, ngo-1973) nezinye izithelo (i-busesi, 1994), njengomthombo wemikhiqizo yokudla, ikofi, i-marse, amantongomane athosiwe, uviniga (marse kanye ne-visscher, 1989). I-Butyl Acetate yenziwa nge-desicution yotshwala abafanele nge-acetic acid noma acetic anhydride (BESESESI, 1994). I-N-Butyl Acetate isetshenziswa njenge-solvent yama-lacquers asuselwa ku-nitrocellulose, inks, kanye nama-adhesives. Okunye ukusetshenziswa kufaka ukwenziwa kwezimpaphe zokufakelwa, ifilimu yezithombe, ingilazi yezokuphepha, namapulasitiki (iBudavari, 1996). Ama-Isomers we-Buty acetate nawo asetshenziswa njengabanambitha ama-ejenti, emikhiqizweni ye-manicure, kanye nezilonda (BESESESI, 1994). I-tert-isomer isetshenziswe njengesengezo sikaphethiloli (iBudavari, 1996). Ingasetshenziswa njenge-sonntetic yezithelo flavour kuswidi, u-ayisikhilimu, ushizi, kanye nezimpahla ezibhakiwe (Dikshith, 2013).

I-Butyl Acetate iyi-Utsheli elingenamibala noma eliphuzi ngephunga eliqinile le-fruity. Ukushisa bese ukunambitheka okumnandi kukhumbuza uphayinaphu. Kwenzeka ngezithelo eziningi futhi kungumsebenzi wama-apula we-apula. I-Butyl Acetate ayihambelani nama-oxididing agents aqinile, ama-acid aqinile, nezisekelo eziqinile.
Kunama-isomers ama-4. Ku-20 ° C, Ubukhulu be-N-Buthyl Isomer ngu-0.8825 g / cm3, kanye nobukhulu be-sec-isomer ngu-0.8758 g / cm3 (BESESESI, 1994). I-N-Butyl Isomer iyancibilika kakhulu kuma-hydrocarbons kanye ne-acetone, futhi ayinakuphikwa nge-ethanol, ethyl ether, ne-chloroform (haynes, 2010). Ihlukanisa amapulasitiki amaningi nama-resin (niosh, 1981).

Uketshezi olucacile, olungenamibala ngephunga eliqinile elifana ne-bananas. Ukunambitheka okumnandi njengokugxila okuphansi (<30 μg / l). Ukuhlaselwa kokutholwa kanye nokuqashelwa kwephunga lomkhawulo we-Odor Cometto-mu? Iz et al. .

Isicelo:

1, njengesinongo, inani elikhulu lamabhanana, amapheya, uphayinaphu, ama-apricots, amapetshisi kanye nama-sitrobheli, amajikijolo nezinye izinhlobo zezinambuzane. Ingasetshenziswa futhi njenge-solvent ye-gum yemvelo kanye ne-sonthetic resin, njll.

I-2, i-solvent ye-organic enhle kakhulu, ene-solubility enhle ye-cellulose acetate butyrate, i-ethyl cellulose, i-clellulose ye-chellulose, i-polystyrene, i-resin eminingi yemvelo efana nama-resin wemvelo afana ne-nitrocellulose varnish, esetshenziswa njenge I-solvent enqubweni yesikhumba sokufakelwa, indwangu kanye nokusebenza kwepulasitiki, isetshenziswa njengokukhipha ekwakhiweni kwama-petroleum ahlukahlukene kanye nenqubo yezemithi, futhi isetshenziswa kuma-apricot, ama-banana, eliphakathi kwezakhi zama-apricot, amanye ama-ejensi amabanga.
I-3, isetshenziswe njenge-reagents yokuhlaziya, amazinga okuhlaziya ama-chromatographic kanye nama-sol.
