Taw qhia
2,4′-Dibromoacetophenone. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 2,4′-Dibromoacetophenone yog xim tsis muaj xim lossis daj crystalline khoom.
- Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li ethanol, ether, thiab benzene.
- Kev ruaj ntseg: 2,4′-Dibromoacetophenone yog qhov ruaj khov nyob rau hauv chav tsev kub, tab sis nws yog nquag combustion ntawm kub kub thiab thaum raug qhib nplaim taws.
Siv:
- 2,4′-Dibromoacetophenone feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis hauv cov chaw kuaj tshuaj.
- Nws kuj tuaj yeem siv rau hauv qee qhov kev cuam tshuam cov organic synthesis, xws li cov tshuaj organometallic tshuaj thiab cov tshuaj tiv thaiv organocatalytic.
Txoj kev:
- 2,4′-dibromoacetophenone feem ntau tuaj yeem ua ke los ntawm bromination ntawm benzophenone. Tom qab cov tshuaj tiv thaiv ntawm benzophenone nrog bromine, cov khoom lag luam tuaj yeem npaj los ntawm cov kauj ruam ua kom huv.
Cov ntaub ntawv kev nyab xeeb:
- 2,4′-Dibromoacetophenone yog qhov txaus ntshai thiab yuav tsum tau siv raws li cov txheej txheem kev nyab xeeb.
- Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab kab mob ua pa tiv thaiv kev ua xua thiab raug mob.
- Ua tib zoo saib xyuas qhov cua zoo thaum siv nws thiab tsis txhob nqus nws cov pa.
- Cov khoom sib xyaw no yuav tsum tau muab khaws cia thiab tswj kom deb ntawm cov nplaim taws qhib thiab qhov chaw kub kub.
