Okwu mmalite

1-Bromobutane bụ mmiri mmiri na-enweghị agba nke nwere isi na-esi ísì ụtọ. Bromobutane nwere mgbanwe na-agafeghị oke na nrụgide vepo, na-agbaze na ihe mgbaze organic, na mmiri na-adịghị ike.

 

1-Bromobutane na-eji ọtụtụ ebe dị ka a brominating reagent na organic njikọ. Enwere ike iji ya dị ka ihe ngbanwe maka mmeghachi omume brominated dị ka mmeghachi omume nnọchi nucleophilic, mmeghachi omume mkpochapụ, na mmeghachi omume nhazigharị. A pụkwara iji ya mee ihe dị ka ihe mgbaze mmepụta ihe, dịka ọmụmaatụ na mmanụ mmanụ iji wepụ wax na mmanụ crude. Ọ na-agbakasị ahụ ma na-egbu egbu, a ga-ejikwa nlezianya mee ya ma kwadebe ya na nlezianya kwesịrị ekwesị mgbe ejiri ya.

 

Usoro a na-ahụkarị maka nkwadebe nke 1-bromobutane bụ mmeghachi omume nke n-butanol na hydrogen bromide. A na-eme mmeghachi omume a n'okpuru ọnọdụ acidic iji mepụta 1-bromobutane na mmiri. Ọnọdụ mmeghachi omume a kapịrị ọnụ na nhọrọ nke catalyst ga-emetụta mkpụrụ na nhọrọ nke mmeghachi omume.

Ọ na-akpasu akpụkpọ ahụ na anya iwe, na iku ume nke ukwuu nwere ike ịkpata nsogbu iku ume na mmebi akwara ozi. A ghaghị ime ya n'ebe ikuku na-ekpo ọkụ nke ọma ma jiri aka nchebe, enyo anya, na ihe na-eku ume. Mgbe ị na-echekwa ma na-ejikwa, zere ebe mgbanye ọkụ na oxidants iji gbochie ihe ize ndụ nke ọkụ na mgbawa.
