4-Valeroylbiphenyl CAS Nr 42916-73-4
Taw qhia
Bifenpentanone, tseem hu ua diphenopyacetone, 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 bifenpentanone:
Zoo:
- Cov tsos mob: Bifenpentone yog xim tsis muaj xim lossis daj daj crystalline khoom.
- Solubility: Nws yog soluble nyob rau hauv feem ntau cov organic solvents, xws li cawv thiab ethers, thiab me ntsis soluble nyob rau hauv dej.
- Cov khoom siv tshuaj lom neeg: Bifenpentone muaj zog txo cov khoom, thiab ua ib qho kev sib xyaw ua ke, nws tuaj yeem koom nrog ntau yam tshuaj lom neeg.
Siv:
Txoj kev:
Muaj ntau ntau txoj hauv kev rau kev npaj ntawm bifenpentanone, thiab cov kev siv feem ntau suav nrog:
- Benzophenone reacts nrog acetophenone nyob rau hauv acidic tej yam kev mob los tsim bifenpentanone.
- Nyob rau hauv lub xub ntiag ntawm sodium oxychloroxysulfate, benzophenone thiab acetopyl bromoethylketone tau txais cov tshuaj tiv thaiv etherification nyob rau hauv alkaline tej yam kev mob kom tau txais bifenpentanone.
Cov ntaub ntawv kev nyab xeeb:
Bifenpentone feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm muaj kev siv, tab sis cov hauv qab no tseem yuav tsum tau sau tseg:
- Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab hnav cov khoom tiv thaiv tus kheej tsim nyog thaum siv nws.
- Tsis txhob sib cuag nrog cov khoom siv hluav taws xob thiab oxidants thaum khaws cia kom tsis txhob muaj hluav taws kub thiab tawg.
- Kev ceev faj yuav tsum tau them rau qhov cua thaum siv thiab khaws cia kom tsis txhob nqus nws cov vapors.
- Yog tias kev nqus tau los yog raug rau bifenpentanone, ntxuav koj cov tawv nqaij tam sim ntawd thiab nrhiav kev pab kho mob.
