I-n-Butyl acetate, eyaziwa ngokuba yi-Butyl acetate, i-organic compound isetyenziswa ngokuqhelekileyo njenge-solvent kwimveliso ye-lacquers kunye nezinye iimveliso. Ikwasetyenziswa njengesiqholo sokwenziwa kweziqhamo ekutyeni okufana neelekese, i-ayisikrimu, itshizi, kunye nezinto ezibhakiweyo. I-butyl acetate ifumaneka kwiindidi ezininzi zeziqhamo, apho kunye nezinye iikhemikhali zinika incasa. ii-apile, ngakumbi zohlobo lwe-Red Delicious, zidlulwa ngokuyinxenye yile khemikhali. Lulwelo olunokutsha olungenambala nevumba elimnandi lebhanana.

I-Butyl acetate i-ester ecacileyo, evuthayo ye-acetic acid eyenzeka kwi-n-, sec-, kunye ne-tert-forms (INCHEM, 2005). I-isomers ye-butyl acetate inesiqhamo, ivumba elifana nebhanana (Furia, 1980). Isomers ye-butyl acetate ifumaneka kwiiapile (Nicholas, 1973) kunye nezinye iziqhamo (Bisesi, 1994), kunye nakwinani lemveliso yokutya, njengetshizi, ikofu, ibhiya, amantongomane aqhotsiweyo, iviniga (iMaarse kunye neVisscher, 1989). I-butyl acetate yenziwa nge-esterification yotywala obufanelekileyo nge-acetic acid okanye i-acetic anhydride (Bisesi, 1994). I-N-butyl acetate isetyenziswa njenge-solvent ye-nitrocellulose-based lacquers, i-inks, kunye ne-adhesives. Olunye usetyenziso lubandakanya ukwenziwa kwesikhumba sokwenziwa, ifilimu yefoto, iglasi yokhuseleko, kunye neeplastiki (Budavari, 1996). Ii-isomers ze-acetate ye-butyl zikwasetyenziswa njengeejenti zokunambitha, kwiimveliso ze-manicure, kunye nanjenge-larvicides (Bisesi, 1994). I-tert-isomer isetyenziswe njenge-additive petroli (Budavari, 1996). Isenokusetyenziswa njengencasa yeziqhamo ezenziweyo kwilekese, i-ayisikrimu, itshizi, kunye nempahla ebhakiweyo (Dikshith, 2013).

Ibutyl acetate lulwelo olungenambala okanye olutyheli olunevumba elinamandla leziqhamo. ukutshisa kwaye ke incasa eswiti esikhumbuza uphayinaphu. Iyenzeka kwiziqhamo ezininzi kwaye iyinxalenye yamavumba eapile. I-acetate ye-butyl ayihambelani ne-oxidizing agents eyomeleleyo, i-acids eqinile, kunye neziseko ezinamandla.
Kukho ii-isomers ezi-4. Kwi-20 °C, ubuninzi be-isomer ye-n-butyl yi-0.8825 g/ cm3, kwaye ubuninzi be-isomer ye-sec-isomeri ngu-0.8758 g/cm3 (Bisesi, 1994). I-isomer ye-n-butyl iyanyibilika kwii-hydrocarbons ezininzi kunye ne-acetone, kwaye iyaxubana ne-ethanol, i-ethyl ether, kunye ne-chloroform (Haynes, 2010). Ichitha iiplastiki ezininzi kunye neerasi (NIOSH, 1981).

Ulwelo olucacileyo, olungenambala kunye nevumba eliqinileyo lesiqhamo elifana nebhanana. Incasa eswiti njengogxininiso oluphantsi (<30 μg/L). Ukufunyaniswa okugqitywe ngovavanyo kunye nokuqondwa kwevumba lokugxila kwi-30 μg / m3 (6.3 ppbv) kunye ne-18 μg / m3 (38 ppbv), ngokulandelanayo (i-Hellman kunye neNcinci, i-1974). Cometto-Mu?iz et al. (2000) kuxelwe ukuba ukurhabula kweempumlo kumqobo kuphakathi kwama-550 ukuya kwi-3,500 ppm.

Isicelo:

I-1, njenge-spice, inani elikhulu leebhanana, iipereyi, iipayinapile, iiapilkosi, iipesika kunye namaqunube, amaqunube kunye nezinye iintlobo zeencasa. Inokusetyenziswa kwakhona njenge-solvent ye-gum yendalo kunye ne-synthetic resin, njl.

2, Isinyibilikisi esigqwesileyo sezinto eziphilayo, kunye nokunyibilika kakuhle kwe-cellulose acetate butyrate, i-cellulose ethyl, irabha eneklorini, i-polystyrene, i-methacrylic resin kunye nee-resin ezininzi zendalo ezifana ne-tannin, i-manila gum, i-dammar resin, njl. Isetyenziswa ngokubanzi kwivanishi ye-nitrocellulose, esetyenziswa njenge i-solvent kwinkqubo yokwenziwa kwesikhumba, ilaphu kunye nokulungiswa kweplastiki, esetyenziswa njenge-extractant kwizinto ezahlukeneyo ukusetyenzwa kwepetroleum kunye nenkqubo yamayeza, ekwasetyenziswa kwi-spice compounding kunye namacandelo ahlukeneyo eapilkosi, ibhanana, ipere, ipayinaphu kunye nezinye ii-agent zokuvumba.
