Taw qhia
Propilate bromide yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm propionyl bromide:
Zoo:
1. Cov tsos mob thiab cov khoom siv: Propionyl bromide yog cov kua tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb.
2. Solubility: Propionyl bromide yog soluble hauv organic solvents, xws li ether thiab benzene, thiab insoluble hauv dej.
3. Kev ruaj ntseg: Propionyl bromide tsis ruaj khov thiab yooj yim hydrolyzed los ntawm dej los tsim acetone thiab hydrogen bromide.
Siv:
1. Organic synthesis: Propionyl bromide yog ib qho tseem ceeb ntawm cov organic synthesis reagent uas yuav siv tau los qhia propionyl pawg lossis bromine atoms.
2. Lwm yam kev siv: propionyl bromide kuj siv tau los npaj acyl bromide derivatives, catalysts rau organic synthesis thiab intermediates hauv tsw chemistry.
Txoj kev:
Kev npaj ntawm propionyl bromide tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm acetone nrog bromine. Cov kev mob tshwm sim tuaj yeem nqa tawm ntawm chav tsev kub lossis los ntawm cua sov.
Cov ntaub ntawv kev nyab xeeb:
1. Propionyl bromide yog qhov khaus heev thiab tuaj yeem ua rau khaus ntawm daim tawv nqaij thiab qhov muag, yog li yuav tsum tau saib xyuas kom tsis txhob sib cuag.
2. Propionyl bromide yog qhov raug rau cov dej hydrolysis thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab kaw kom nruj.
3. Cov cua zoo yuav tsum tau khaws cia thaum siv kom tsis txhob nqus nws cov vapor.
4. Ua raws li cov txheej txheem kev nyab xeeb cuam tshuam thaum khaws cia, kev thauj mus los thiab tuav, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv.
