n-butyl acetate, omwe amadziwikanso kuti Nyyl Acetate, ndi gawo lokhazikika lomwe limagwiritsidwa ntchito ngati chosungunulira popanga ma anzeru ndi zinthu zina. Amagwiritsidwanso ntchito ngati zipatso zopangidwa muzakudya monga maswiti, ayisikilimu, tchizi, ndi zinthu zophika. Butyl acetate imapezeka m'mitundu yambiri ya zipatso, komwe pamodzi ndi mankhwala ena amapereka zonunkhira. Maapulo, makamaka ofiira ofiira, amakhala ndi gawo limodzi ndi mankhwalawa. Ndi madzi opanda utoto wopanda mafuta ndi fungo lokoma la nthochi.

Chyl Acetate ndi ester yomveka bwino, yoyaka ya acetic acid yomwe imachitika mu n-, ma tert, ndi term, 2005). Cyyl acetate ma famu ali ndi chilema, zonunkhira ngati zonunkhira (Furlia, 1980). Maomers a ntecetate acetate amapezeka m'maapulo (Nicholas, 1973) ndi zipatso zina (basi, mtedza), viniga (1089). Butyl acetate imapangidwa kudzera pakumwa mankhwalawa ndi acetic acid kapena acetic anhydride (bruk, 1994). N -Tyl acetate imagwiritsidwa ntchito ngati zosungunulira za masamba a nitrocellulose, inks, ndi zomatira. Maugwiritsidwe ena amaphatikizidwa kupanga ziweto zopanda, kanema wa zithunzi, galasi la chitetezo, ndi pulasitiki (Dodacari, 1996). Asomers a mbyyl acetate amagwiritsidwanso ntchito ngati othandizira akukola, muzogulitsa manichire, ndi zipatso za Larvicides (BIDES, 1994). Asodzi-isomer wagwiritsidwa ntchito ngati owonjezera owonjezera mafuta (Budacari, 1996). Itha kugwiritsidwa ntchito ngati zipatso zonunkhira m'maswiti, ayisikilimu, tchizi, ndi zinthu zophika (dikshith, 2013).

Butyl acetate ndi mtundu wopanda utoto kapena wachikasu wokhala ndi fungo lamphamvu lolimba. Kuyaka kenako kukoma kukoma kumakumbukiranso za chinanazi. Zimachitika mu zipatso zambiri ndipo imakhazikika pa apulo. Butyl acetate sagwirizana ndi othandizira amphamvu oxidizing, acid olimba, ndi zitsulo zolimba.
Pali mitundu 4. Pa 20 ° C, kachulukidwe ka isomer ndi 0.8825 g / cm3, ndipo kachulukidwe ka sec-isomer ndi 0.8758 g / cm3 (bassi, 1994). The N-Butyl Asomer ndikusungunuka mu hydrocarbons ambiri ndi acetol, ndipo ndizolakwika ndi ethanol, ethyl ether, ndi chloroform (haynes, 2010). Imasungunuka mapulatipi ambiri (niosh, 1981).

Madzi omveka bwino, opanda utoto okhala ndi fungo lolimba lofanana ndi nthochi. Kukoma kosangalatsa ngati wotsika kwambiri (<30 μg / l). Poyeserera kuzindikirika ndi kuzindikiridwa kununkhira kwa fungo la misozi inali 30 μg / m3 (6.3 PPBV) ndi 18 μg / m3 (38 ppbv, 1974). Comwetto-mu? Iz et al. .

Ntchito:

1, monga zonunkhira, nthochi zambiri, mapeyala, chinanazi, ma apricots, mapichesi ndi sitiroberi, zipatso ndi mitundu ina ya zonunkhira. Itha kugwiritsidwanso ntchito ngati zosungunulira zachilengedwe ndi zopanga, etc.

2, zosungunulira bwino kwambiri zodzikongoletsa, ndi kusungunuka bwino kwa cellulose aceuluse, manhacryllic vamber, zopangidwa ndi pulasitiki, zosinthika ndi pulasitiki, zomwe zimagwiritsidwa ntchito ngati Zowonjezera mu ma petroleum posintha ma petroleum kukonzanso, zomwe zimagwiritsidwanso ntchito popanga zonunkhira komanso zigawo zingapo za apricot, nthochi, peanagle ndi mankhwala ena onunkhira.
