Ibikoresho bya Shimi:

n-Butyl acetate, izwi kandi ku izina rya Butyl acetate, ni ifumbire mvaruganda ikunze gukoreshwa nk'umusemburo mu gukora lacques n'ibindi bicuruzwa. Ikoreshwa kandi nk'imbuto ya sintetike ihumura ibiryo nka bombo, ice cream, foromaje, nibicuruzwa bitetse. Butyl acetate iboneka mubwoko bwinshi bwimbuto, aho hamwe nindi miti itanga uburyohe buranga. pome, cyane cyane yubwoko butukura buryoshye, ihindurwamo igice niyi miti. Nibintu bitagira ibara byaka umuriro bifite impumuro nziza yigitoki.

Butyl acetate ni ester isobanutse, yaka ya acide acike iboneka muri n-, sec-, na tert- (INCHEM, 2005). Isomers ya Butyl acetate ifite imbuto, impumuro imeze nk'igitoki (Furia, 1980). Isomers ya butyl acetate iboneka muri pome (Nicholas, 1973) nizindi mbuto (Bisesi, 1994), ndetse no mubiribwa byinshi, nka foromaje, ikawa, byeri, imbuto zokeje, vinegere (Maarse na Visscher, 1989). Butyl acetate ikorwa hifashishijwe esterifike ya alcool hamwe na acide acike cyangwa anhydride ya acetike (Bisesi, 1994). N-butyl acetate ikoreshwa nkigishishwa cya nitrocellulose ishingiye kuri lacquer, wino, hamwe na adhesives. Ibindi bikoreshwa birimo gukora impu zubukorikori, firime yerekana amafoto, ikirahure cyumutekano, na plastiki (Budavari, 1996). Isomers ya butyl acetate nayo ikoreshwa nkibintu bihumura neza, mubicuruzwa bya manicure, ndetse na larvicide (Bisesi, 1994). Tert-isomer yakoreshejwe nk'inyongera ya lisansi (Budavari, 1996). Irashobora gukoreshwa nkimbuto yubukorikori iryoshye muri bombo, ice cream, foromaje, nibicuruzwa bitetse (Dikshith, 2013).

Butyl acetate ni ibara ritagira ibara cyangwa umuhondo rifite impumuro nziza yimbuto. gutwika hanyuma uburyohe buryoshye bwibutsa inanasi. Biboneka mu mbuto nyinshi kandi ni bigize impumuro ya pome. Butyl acetate ntishobora kubangikanya ibintu bikomeye bya okiside, acide ikomeye, hamwe nishingiro rikomeye.
Hano hari isomers 4. Kuri 20 ° C, ubucucike bwa n-butyl isomer ni 0,8825 g / cm3, naho ubucucike bwa sec-isomer ni 0.8758 g / cm3 (Bisesi, 1994). Isomer ya n-butyl irashonga muri hydrocarbone nyinshi na acetone, kandi ntishobora gukoreshwa na Ethanol, Ethyl ether, na chloroform (Haynes, 2010). Irashonga plastike nyinshi hamwe na resin (NIOSH, 1981).

Amazi meza, atagira ibara numunuko wimbuto ukomeye usa numuneke. Uburyohe buryoshye nkibintu bike (<30 μg / L). Ubushakashatsi bwerekanwe kubushakashatsi no kumenyekanisha impumuro yumubyimba ni 30 μg / m3 (6.3 ppbv) na 18 μg / m3 (38 ppbv), (Hellman na Small, 1974). Cometto-Mu? Iz n'abandi. .

Gusaba:

1, nkibirungo, umubare munini wibitoki, amapera, inanasi, amata, pashe na strawberry, imbuto nubundi bwoko bwa flavours. Irashobora kandi gukoreshwa nkigishishwa cya gum naturel na resinike ya sintetike, nibindi.

2 、 Indangakamere nziza cyane, hamwe na solubose acetate butyrate, etyl selulose, reberi ya chlorine, polystirene, methacrylic resin hamwe nibisigara byinshi nka tannin, manila gum, dammar resin, nibindi bikoreshwa cyane muri varish ya nitrocellulose, ikoreshwa nka solvent mugikorwa cyo gutunganya uruhu rwubukorikori, imyenda no gutunganya plastike, bikoreshwa nkibisohoka mubikorwa bitandukanye bya peteroli no gutunganya imiti, nabyo ikoreshwa mu guhuza ibirungo hamwe nibice bitandukanye bya apicot, igitoki, amapera, inanasi nibindi bikoresho bihumura.
3 、 Byakoreshejwe nkibisesengura reagent, ibipimo byisesengura bya chromatografique hamwe na solvets.
