Njirimara kemịkalụ:

n-Butyl acetate, nke a makwaara dị ka Butyl acetate, bụ ngwakọta organic a na-ejikarị dị ka ihe mgbaze na mmepụta nke lacquers na ngwaahịa ndị ọzọ. A na-ejikwa ya dị ka ụtọ mkpụrụ osisi sịntetik n'ime nri ndị dị ka swiiti, ice cream, cheeses, na ngwaahịa esitere. A na-achọta Butyl acetate n'ọtụtụ ụdị mkpụrụ osisi, ebe ya na kemịkalụ ndị ọzọ na-enye ụtọ njirimara. apụl, karịsịa nke ụdị dị iche iche na-acha uhie uhie, na-esi na kemịkalụ a na-esi ísì ụtọ. Ọ bụ mmiri mmiri na-enweghị agba nke na-esi ísì ụtọ nke banana.

Butyl acetate bụ ester doro anya, ọkụ ọkụ nke acetic acid nke na-eme na n-, sec-, na tert-ụdị (INCHEM, 2005). Butyl acetate isomers nwere mkpụrụ osisi, isi dị ka banana (Furia, 1980). A na-ahụ Isomers nke butyl acetate na apụl (Nicholas, 1973) na mkpụrụ osisi ndị ọzọ (Bisesi, 1994), yana n'ọtụtụ ngwaahịa nri, dị ka cheese, kọfị, biya, mkpụrụ a ṅara n'ọkụ, mmanya mmanya (Maarse na Visscher. 1989). A na-arụpụta Butyl acetate site na ibelata mmanya dị iche iche nwere acetic acid ma ọ bụ acetic anhydride (Bisesi, 1994). N-butyl acetate na-eji dị ka ihe mgbaze maka nitrocellulose dabeere lacquers, ink, na adhesives. Ojiji ndị ọzọ gụnyere imepụta akpụkpọ anụ arụrụ arụ, ihe nkiri foto, iko nchekwa, na plastik (Budavari, 1996). A na-ejikwa Isomers nke butyl acetate mee ihe dị ka ihe na-esi ísì ụtọ, na ngwaahịa manicure, yana dị ka larvicides (Bisesi, 1994). Eji tert-isomer dị ka ihe mgbakwunye mmanụ ụgbọala (Budavari, 1996). Enwere ike iji ya dị ka ụtọ mkpụrụ osisi sịntetik na swiit, ice cream, cheeses, na ngwaahịa esi nri (Dikshith, 2013).

Butyl acetate bụ mmiri mmiri na-enweghị agba ma ọ bụ odo odo nwere isi mkpụrụ osisi siri ike. ọkụ na mgbe ahụ ụtọ uto reminiscent nke painiapulu. Ọ na-apụta n'ọtụtụ mkpụrụ osisi ma bụrụ ihe mejupụtara apụl aromas. Butyl acetate ekwekọghị na ndị ọrụ oxidizing siri ike, acid siri ike, na ntọala siri ike.
Enwere 4 isomers. Na 20 Celsius C, njupụta nke isomer n-butyl bụ 0.8825 g/ cm3, na njupụta nke sec-isomer bụ 0.8758 g/cm3 (Bisesi, 1994). N-butyl isomer bụ soluble n'ime ọtụtụ hydrocarbons na acetone, na ọ na-miscible na ethanol, ethyl ether, na chloroform (Haynes, 2010). Ọ na-agbaze ọtụtụ plastik na resins (NIOSH, 1981).

Mmiri mmiri doro anya na-enweghị ụcha nke nwere isi mkpụrụ osisi siri ike nke yiri unere. Ụtọ ụtọ dị ka obere mkpokọta (<30 μg / L). Nchọpụta achọpụtara na nnwale na nnabata ọnụ ụzọ isi bụ 30 μg/m3 (6.3 ppbv) na 18 μg/m3 (38 ppbv), n'otu n'otu (Hellman na obere, 1974). Cometto-Mu?iz et al. (2000) kọrọ na ọnụ ụzọ nrịba nke imi sitere na 550 ruo 3,500 ppm.
