Okwu mmalite
N-butanol, nke a makwaara dị ka butanol, bụ ngwakọta organic, ọ bụ mmiri mmiri na-enweghị agba nke nwere isi mmanya pụrụ iche. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke n-butanol:
Ogo:
1. Njirimara anụ ahụ: Ọ bụ mmiri mmiri na-enweghị agba.
2. Chemical Njirimara: Ọ nwere ike agbaze na mmiri na organic solvents, na bụ moderately pola compound. Ọ nwere ike ịbụ oxidized na butyraldehyde na butyric acid, ma ọ bụ ọ nwere ike ịmịcha ya ka ọ bụrụ butene.
Jiri:
1. Iji ụlọ ọrụ eme ihe: Ọ bụ ihe mgbaze dị mkpa ma nwee ọtụtụ ngwa na ụlọ ọrụ kemịkalụ dị ka mkpuchi, inks, na nchacha.
2. Laboratory ojiji: Enwere ike iji ya dị ka ihe mgbaze na-eme ka protein protein na-atụgharị, a na-ejikarị ya eme ihe na nyocha biochemical iji kpata mmeghachi omume.
Usoro:
1. Butylene hydrogenation: Mgbe mmeghachi omume hydrogenation gasịrị, butene na-emeghachi omume na hydrogen n'ihu onye na-eme ihe (dị ka ihe nickel catalyst) iji nweta n-butanol.
2. Mmeghachi omume akpịrị ịkpọ nkụ: butanol na-emeghachi omume na acid siri ike (dị ka sulfuric acid concentrated) na-emepụta butene site na mmeghachi ahụ nke akpịrị ịkpọ nkụ, mgbe ahụ butene bụ hydrogenated iji nweta n-butanol.
Ozi nchekwa:
1. Ọ bụ mmiri mmiri na-ere ọkụ, zere kọntaktị na isi iyi ọkụ, ma zere ọkụ na-emeghe na gburugburu okpomọkụ dị elu.
3. O nwere ihe na-egbu egbu, zere imetụ akpụkpọ ahụ na anya anya, ma zere ikuru uzuoku ya.
4. Mgbe ị na-echekwa ya, a ga-echekwa ya na oghere mechiri emechi, pụọ na oxidants na ọkụ ọkụ, ma chekwaa ya na ụlọ okpomọkụ.
