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 kwiintlobo ezininzi zeziqhamo, apho kunye nezinye iikhemikhali zinika incasa yeempawu. ii-apile, ingakumbi ezizintlobo-ntlobo ze-Red Delicious, zi- fl avored 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 of butyl acetate zifumaneka apile (Nicholas, 1973) kunye nezinye iziqhamo (Bisesi, 1994), kwakunye nenani iimveliso zokutya, ezifana ushizi, ikofu, ubhiya, amantongomane agcadiweyo, iviniga (Maarse kunye Visscher, 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 ye-petroli (Budavari, 1996). Isenokusetyenziswa njengencasa yokwenziwa kweziqhamo kwilekese, i-ayisikrimu, itshizi, kunye nezinto ezibhakiweyo (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 umqobo wokurhabula ngeempumlo usuka malunga nama-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 egqwesileyo organic, kunye nokunyibilika elungileyo for cellulose acetate butyrate, cellulose ethyl, irabha chlorinated, polystyrene, methacrylic resin kunye nentlaka ezininzi zendalo ezifana tannin, manila gum, dammar resin, njl. Isetyenziswa ngokubanzi kwivanishi ye-nitrocellulose, esetyenziswa njenge-soltificial esetyenziswa kwi-soltificial kwi-processing ye-plastic, i-extract ye-soltificial kunye ne-substrate yeplastiki. ukusetyenzwa kwepetroleum kunye nenkqubo yamayeza, ekwasetyenziswa kwi-spice compounding kunye namacandelo ahlukeneyo eapilkosi, ibhanana, ipere, ipayinaphu kunye nezinye ii-agent zokuvumba.
