Taw qhia

1-Bromobutane yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw. Bromobutane muaj nruab nrab volatility thiab vapor siab, soluble nyob rau hauv organic solvents, thiab insoluble nyob rau hauv dej.

 

1-Bromobutane yog dav siv los ua brominating reagent hauv organic synthesis. Nws tuaj yeem siv los ua lub substrate rau cov tshuaj tiv thaiv brominated xws li cov tshuaj tiv thaiv nucleophilic hloov pauv, tshem tawm cov tshuaj tiv thaiv, thiab rov kho cov tshuaj tiv thaiv. Nws kuj tseem siv tau los ua cov kuab tshuaj ua lag luam, piv txwv li hauv roj av extraction kom tshem tawm cov quav ciab los ntawm cov roj av. Nws yog khaus thiab lom, thiab yuav tsum tau ceev faj thiab nruab nrog kev ceev faj tsim nyog thaum siv.

 

Ib txoj hauv kev zoo rau kev npaj ntawm 1-bromobutane yog los ntawm cov tshuaj tiv thaiv ntawm n-butanol nrog hydrogen bromide. Cov tshuaj tiv thaiv no yog nqa tawm nyob rau hauv acidic tej yam kev mob los tsim 1-bromobutane thiab dej. Cov kev mob tshwm sim tshwj xeeb thiab kev xaiv ntawm catalyst yuav cuam tshuam rau cov txiaj ntsig thiab kev xaiv ntawm cov tshuaj tiv thaiv.

Nws ua rau khaus ntawm daim tawv nqaij thiab qhov muag, thiab nqus tau ntau dhau tuaj yeem ua rau ua pa nyuaj thiab puas hlwb. Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated thiab nrog cov hnab looj tes tiv thaiv, tsom iav, thiab lub tshuab ua pa hnav. Thaum khaws cia thiab tuav, cia kom deb ntawm qhov hluav taws kub thiab oxidants kom tsis txhob muaj hluav taws kub thiab tawg.
