Isingeniso

I-1-Bromobutane iwuketshezi olungenambala olunephunga eliphunga elingavamile. I-Bromobutane ine-volatility emaphakathi kanye nomfutho womhwamuko, iyancibilika kuma-organic solvents, futhi ayincibiliki emanzini.

 

I-1-Bromobutane isetshenziswa kabanzi njenge-reagent brominating ku-organic synthesis. Ingasetshenziswa njenge-substrate yokusabela kwe-brominated njengokusabela kwe-nucleophilic substitution, ukusabela kokuqeda, nokusabela kokuhlela kabusha. Ingasetshenziswa futhi njengesinyibilikisi sezimboni, isibonelo ekukhishweni kwe-petroleum ukuze kukhishwe i-wax kuwoyela ongahluziwe. Iyacasula futhi inobuthi, futhi kufanele isingathwe ngokuqapha futhi ifakwe izinyathelo ezifanele zokuqapha lapho isetshenziswa.

 

Indlela evamile yokulungiswa kwe-1-bromobutane ukusabela kwe-n-butanol nge-hydrogen bromide. Lokhu kusabela kwenziwa ngaphansi kwezimo ezimuncu ukukhiqiza i-1-bromobutane namanzi. Izimo ezithile zokusabela kanye nokukhetha kwe-catalyst kuzothinta isivuno nokukhetha kokusabela.

Kuyacasula esikhumbeni nasemasweni, futhi ukuhogela kakhulu kungabangela ubunzima bokuphefumula kanye nokulimala kwemizwa. Kufanele wenziwe endaweni engenawo umoya futhi kugqokwe amagilavu ​​okuvikela, izibuko kanye nezinsimbi zokuphefumula. Lapho ugcina futhi uphatha, gwema imithombo yokuthungela kanye nama-oxidants ukuvimbela ingozi yomlilo nokuqhuma.
