Mawu Oyamba

1-Bromobutane ndi madzi opanda mtundu omwe amanunkhira mwachilendo. Bromobutane ili ndi kusinthasintha kwapakati komanso kuthamanga kwa nthunzi, imasungunuka mu zosungunulira za organic, komanso yosasungunuka m'madzi.

 

1-Bromobutane imagwiritsidwa ntchito kwambiri ngati brominating reagent mu organic synthesis. Itha kugwiritsidwa ntchito ngati gawo lapansi pamachitidwe a brominated monga ma nucleophilic substitution reactions, kuchotseratu, ndikusinthanso. Itha kugwiritsidwanso ntchito ngati chosungunulira m'mafakitale, mwachitsanzo potulutsa mafuta kuti achotse sera kumafuta akuda. Zimakwiyitsa komanso zapoizoni, ndipo ziyenera kusamaliridwa mosamala komanso zokhala ndi njira zodzitetezera zikagwiritsidwa ntchito.

 

Njira yodziwika yokonzekera 1-bromobutane ndi momwe n-butanol imachitira ndi hydrogen bromide. Izi zimachitika pansi pa acidic kuti apange 1-bromobutane ndi madzi. The enieni anachita zinthu ndi kusankha chothandizira zingakhudze zokolola ndi selectivity wa anachita.

Zimakwiyitsa khungu ndi maso, ndipo kutulutsa mpweya wambiri kungayambitse vuto la kupuma komanso kuwonongeka kwa minyewa. Ayenera kuchitikira pamalo olowera mpweya wabwino komanso atavala magolovesi oteteza, magalasi agalasi, ndi zida zopumira. Posunga ndikugwira, samalani ndi zoyatsira ndi zoteteza kuopsa kwa moto ndi kuphulika.
