Meatotino tau vailaau:

n-Butyl acetate, lea e taʻua foi o le Butyl acetate, o se faʻalapotopotoga faʻapitoa e masani ona faʻaaogaina e fai ma solvent i le gaosiga o lacquers ma isi oloa. E fa'aaogaina fo'i e fai ma mea e fa'amalieina ai fualaau 'aina i mea'ai e pei o lole, aisakulimi, sisi, ma mea tao tao. O le butyl acetate e maua i le tele o ituaiga o fualaau 'aina, faatasi ai ma isi vailaʻau e maua ai le tofo uiga. o apu, aemaise o le ituaiga Red Delicious, o loʻo faʻafefe i se vaega e lenei vailaʻau. Ose vai e mu e leai se lanu ma se manogi suamalie o le fa'i.

O le butyl acetate ose ester manino ma mu o le acetic acid e tupu i le n-, sec-, ma le tertforms (INCHEM, 2005). Butyl acetate isomers e iai lona manogi suamalie e pei o le fa'i (Furia, 1980). Isomers o le butyl acetate o loʻo maua i apu (Nicholas, 1973) ma isi fua (Bisesi, 1994), faʻapea foʻi ma le tele o meaʻai, e pei o sisi, kofe, pia, nati tunu, vineka (Maarse ma Visscher, 1989). Butyl acetate e gaosia e ala i le esterification o le ava fa'atasi ma le acetic acid po'o le acetic anhydride (Bisesi, 1994). O le N-butyl acetate o loʻo faʻaaogaina e avea o se solvent mo nitrocellulose-based lacquers, inks, ma faʻapipiʻi. O isi fa'aoga e aofia ai le gaosiaina o pa'u fa'akomepiuta, ata tifaga, tioata saogalemu, ma palasitika (Budavari, 1996). O isomers o le butyl acetate o loʻo faʻaaogaina foi e fai ma mea e tofo ai, i oloa manicure, ma pei o larvicides (Bisesi, 1994). O le tert-isomer ua faʻaaogaina e fai ma mea faʻapipiʻi penisini (Budavari, 1996). E mafai ona fa'aaogaina e fai ma mea e fa'amalieina ai fualaau 'aina i lole, aisakulimi, sisi, ma mea tao tao (Dikshith, 2013).

Butyl acetate o se vai e leai se lanu pe samasama ma se manogi manogi malosi. mu ona tofo suamalie e manatua ai le fala. E tupu i le tele o fualaau aina ma o se vaega o le manogi apu. Butyl acetate e le fetaui ma mea faʻamaʻi faʻamaʻi malosi, malosi malosi, ma faʻavae malosi.
E 4 isomers. I le 20 °C, o le mamafa o le n-butyl isomer o le 0.8825 g / cm3, ma le mamafa o le sec-isomer o le 0.8758 g / cm3 (Bisesi, 1994). O le isomer n-butyl e mafai ona solu i le tele o hydrocarbons ma acetone, ma e faʻafefiloi ma ethanol, ethyl ether, ma chloroform (Haynes, 2010). E fa'amuta le tele o palasitika ma resini (NIOSH, 1981).

O le vai manino, e leai se lanu ma se manogi manogi malosi e pei o fa'i. Tofo suamalie e pei o le maualalo o fa'atonuga (<30 μg/L). Fa'ata'ita'iga fa'amoemoeina su'esu'ega ma le fa'ailoaina o le manogi o le fa'ailoga o le 30 μg/m3 (6.3 ppbv) ma le 18 μg/m3 (38 ppbv), i le faasologa (Hellman and Small, 1974). Cometto-Mu?iz et al. (2000) lipotia mai nasal pungency threshold concentrations mai le 550 i le 3,500 ppm.

Talosaga:

1, e pei o se mea manogi, se numera tele o faʻi, pears, pineapples, apricots, peaches ma strawberries, vine ma isi ituaiga o tofo. E mafai foʻi ona faʻaaogaina e avea o se solvent mo gum masani ma resin synthetic, ma isi.

2, sili ona solu solu, ma solubility lelei mo cellulose acetate butyrate, ethyl cellulose, pa'u chlorinated, polystyrene, resini methacrylic ma le tele o resini natura e pei o tannin, manila gum, dammar resin, ma isi E masani ona faaaoga i le nitrocellulose varnish, faaaogaina e pei solvent i le faagasologa o le paʻu faʻapitoa, ie ma palasitika gaosiga, faʻaaogaina e avea ma suʻega i le gaosiga o suauʻu eseese ma pharmaceutical process, faʻaaogaina foi i mea manogi faʻafefiloi ma vaega eseese o apricot, faʻi, pea, pineapple ma isi mea manogi manogi.
3、 Fa'aaogaina e fai ma su'esu'ega su'esu'e, tulaga fa'ata'ita'iga chromatographic ma solvents.
