Xwm:
1-bromo-2-methyl-1-propene yog cov xim tsis muaj xim rau daj daj daj nrog cov tshuaj tsw qab tshwj xeeb. Nws muaj qhov kub tsis tshua muaj kub thiab yog volatile. Lub compound yog denser dua dej thiab insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv organic solvents xws li ethanol thiab chloroform.
Siv:
1-bromo-2-methyl-1-propene tuaj yeem siv los ua cov khoom pib thiab nruab nrab hauv cov organic synthesis. Nws yog dav siv nyob rau hauv cov tshuaj lom neeg cov tshuaj tiv thaiv, xws li hloov cov tshuaj tiv thaiv, condensation tshua, oxidation tshuaj tiv thaiv thiab lwm yam. Nws kuj tseem siv tau rau hauv thaj chaw xws li tshuaj synthesis thiab kev npaj dye.
Txoj kev:
Kev npaj ntawm 1-bromo-2-methyl-1-propene tuaj yeem ua tau los ntawm ntau txoj kev. Ib txoj hauv kev zoo tshaj plaws yog los ua cov tshuaj methacrylic acid nrog bromine nyob rau hauv lub xub ntiag ntawm sulfuric acid muab 1-bromo-2-methyl-1-propene. Lwm txoj kev yog los ua 2-methyl-1-propene nrog bromine hauv cov organic hnyav.
Cov ntaub ntawv kev nyab xeeb:
1-bromo-2-methyl-1-propene yog ib qho tshuaj lom neeg uas yuav ua rau khaus ntawm daim tawv nqaij thiab qhov muag. Hnav cov hnab looj tes tiv thaiv thiab tsom iav thaum siv thiab xyuas kom muaj chaw ua haujlwm zoo. Tsis tas li ntawd, nws tseem yog cov kua dej uas muaj hluav taws kub thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Thaum khaws cia thiab nqa, yuav tsum tau saib xyuas kom tsis txhob muaj oxidants thiab acids muaj zog, thiab kom deb ntawm cov menyuam yaus thiab qhov chaw hluav taws. Yog tias kis tau los yog noj, nrhiav kev kho mob tam sim ntawd.
