Guryaha Kiimikada:

n-Butyl acetate, oo sidoo kale loo yaqaan Butyl acetate, waa iskudhis dabiici ah oo caadi ahaan loo isticmaalo dareeraha wax soo saarka lacquers iyo alaabta kale. Waxa kale oo loo isticmaalaa sida dhadhanka miraha synthetic ee cuntooyinka sida nacnaca, jalaatada, farmaajada, iyo alaabta la dubay. Butyl acetate waxaa laga helaa noocyo badan oo miro ah, halkaas oo ay la socdaan kiimikooyinka kale waxay bixiyaan dhadhan sifo. tufaaxa, gaar ahaan noocyada casaanka ah ee macaan, ayaa qayb ka mid ah kiimikadan lagu beeray. Waa dareere guban kara oo aan midab lahayn oo leh ur macaan oo muus ah.

Butyl acetate waa ester cad, guban kara oo ah acetic acid kaas oo ku dhaca n-, sek-, iyo foomamka tert- (INCHEM, 2005). Butyl acetate isomers waxay leeyihiin miro leh, ur muus u eg (Furia, 1980). Isomers of butyl acetate waxaa laga helaa tufaaxa (Nicholas, 1973) iyo miraha kale (Bisesi, 1994), iyo sidoo kale tiro cunto ah, sida farmaajo, qaxwo, biir, nuts duban, khal (Maarse iyo Visscher, 1989). Butyl acetate waxaa lagu soo saaray sifeynta khamriga kala duwan oo leh acetic acid ama acetic anhydride (Bisesi, 1994). N-butyl acetate waxaa loo isticmaalaa dareere ahaan nitrocellulose-ku-saleysan lacquers, khadadka, iyo xabagta. Isticmaalka kale waxaa ka mid ah samaynta maqaar macmal ah, filim sawireed, muraayad badbaado, iyo balaastiig (Budavari, 1996). Isomers of butyl acetate ayaa sidoo kale loo isticmaalaa sida walxaha dhadhanka, alaabta manicure, iyo larvicides ahaan (Bisesi, 1994). Tert-isomer-ka waxa loo isticmaalay sidii shidaal lagu daro (Budavari, 1996). Waxaa laga yaabaa in loo isticmaalo dhadhanka miraha synthetic ee nacnaca, jalaatada, jiiska, iyo alaabta la dubay (Dikshith, 2013).

Butyl acetate waa dareere aan midab lahayn ama huruud ah oo leh ur miro xoog leh. gubanaya ka dibna dhadhan macaan oo u eg cananaaska. Waxay ku dhacdaa miro badan waxayna ka kooban tahay udgoonka tufaaxa. Butyl acetate waa mid aan la jaan qaadi karin wakiilada oksaydhiyeyaasha xooggan, acids xooggan, iyo saldhigyada xooggan.
Waxaa jira 4 isomers. At 20 °C, cufnaanta isomer n-butyl waa 0.8825 g/cm3, iyo cufnaanta sek-isomer waa 0.8758 g/cm3 (Bisesi, 1994). N-butyl isomer-ku waxa uu ku milmay inta badan hydrocarbons iyo acetone, waxana uu la khaldaa ethanol, ethyl ether, iyo chloroform (Haynes, 2010). Waxay milmaan balaastig iyo resins badan (NIOSH, 1981).

dareere cad oo aan midab lahayn oo leh ur miro xoog leh oo u eg muuska. Dhadhan macaan sida xaddi hoose (<30 μg/L). Tijaabada lagu go'aamiyay ogaanshaha iyo aqoonsiga urta xadka urta waxay ahaayeen 30 μg/m3 (6.3 ppbv) iyo 18 μg/m3 (38 ppbv), siday u kala horreeyaan (Hellman iyo Small, 1974). Cometto-Mu?iz iyo al. (2000) ayaa la sheegay in xajmiyada marinnada sanka ee sanka ay u dhexeeyaan qiyaastii 550 ilaa 3,500 ppm.

Codsiga:

1, sida xawaashka, tiro badan oo ah muus, isteroberi, cananaaska, khudaar, fersken iyo strawberries, berry iyo noocyada kale ee dhadhanka. Waxa kale oo loo isticmaali karaa dareere ahaan cirridka dabiiciga ah iyo resin synthetic, iwm.

2, dareere organic heer sare ah, oo leh milmo wanaagsan oo loogu talagalay cellulose acetate butyrate, ethyl cellulose, caag chlorinated, polystyrene, xabagta methacrylic iyo xabagta dabiiciga ah oo badan sida tannin, xanjo manila, xabagta dammar, iwm waxaa si ballaaran loo isticmaalaa in varnish nitrocellulose, loo isticmaalo sida dareere habka of maqaar macmal ah, dhar iyo processing caag ah, loo isticmaalo soosaaray in processing batroolka kala duwan iyo habka dawooyinka, oo sidoo kale loo isticmaalo isku-darka udgoonka iyo qaybaha kala duwan ee khudaar, muuska, pear, cananaaska iyo walxaha kale ee udgoonka.
3. Loo isticmaalo sida reagents gorfaynta, heerarka falanqaynta chromatographic iyo dareerayaasha.
