Intshayelelo

I-1-Bromobutane lulwelo olungenambala kunye nevumba elimnandi elingaqhelekanga. I-Bromobutane ine-moderal volatility kunye noxinzelelo lwe-vapor, i-soluble kwi-solvents ye-organic, kwaye ayinyibiliki emanzini.

 

I-1-Bromobutane isetyenziswa ngokubanzi njenge-reagent brominating kwi-organic synthesis. Ingasetyenziswa njenge substrate ukwenzela reactions brominated ezifana reactions nucleophilic substitution, reactions ukuphelisa, kunye rearrangement reactions. Isenokusetyenziswa njengesinyibilikisi semizi-mveliso, umzekelo kwi-petroleum extraction ukususa i-wax kwi-oyile ekrwada. Iyacaphukisa kwaye inetyhefu, kwaye kufuneka iphathwe ngononophelo kwaye ixhotyiswe ngamanyathelo okhuseleko afanelekileyo xa isetyenziswa.

 

Indlela eqhelekileyo yokulungiswa kwe-1-bromobutane kukusabela kwe-n-butanol kunye ne-hydrogen bromide. Le mpendulo iqhutyelwa phantsi kweemeko ze-acidic ukuvelisa i-1-bromobutane kunye namanzi. Iimeko ezithile zokusabela kunye nokukhethwa kwe-catalyst kuya kuchaphazela isivuno kunye nokukhetha kokuphendula.

Iyacaphukisa ulusu kunye namehlo, kwaye ukuphefumla kakhulu kunokubangela ubunzima bokuphefumla kunye nomonakalo wemithambo-luvo. Kufuneka wenziwe kwindawo engenamoya kwaye kunxitywe iiglavu zokhuselo, iiglasi kunye nezitshizi zokuphefumla. Xa ugcina kwaye uphatha, zigcine kude nemithombo yokutshisa kunye nee-oxidants ukuthintela umngcipheko womlilo kunye nokudubula.
