Taw qhia
Trifluoromethylbenzaldehyde (tseem hu ua TFP aldehyde) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm trifluoromethylbenzaldehyde:
Zoo:
- Tshwm sim: Trifluoromethylbenzaldehyde yog cov kua tsis muaj xim rau daj nrog cov ntxhiab tsw benzaldehyde.
- Solubility: Nws yog soluble hauv ether thiab ester cov kuab tshuaj, me ntsis soluble hauv aliphatic hydrocarbons, tab sis insoluble hauv dej.
Siv:
- Hauv kev tshawb fawb tshuaj, nws tuaj yeem siv los ua ke rau lwm cov organic tebchaw thiab cov ntaub ntawv.
Txoj kev:
Trifluoromethylbenzaldehyde feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm benzaldehyde thiab trifluoroformic acid. Thaum lub sij hawm cov tshuaj tiv thaiv, nws yog feem ntau nqa tawm nyob rau hauv alkaline tej yam kev mob los pab txhawb cov tshuaj tiv thaiv. Cov txheej txheem synthesis tshwj xeeb tuaj yeem piav qhia meej hauv cov ntaub ntawv lossis patents ntawm organic synthesis.
Cov ntaub ntawv kev nyab xeeb:
- Trifluoromethylbenzaldehyde yog cov organic compound, yog li yuav tsum tau ceev faj thaum siv nws, thiab cov kev khiav hauj lwm cov lus qhia yuav tsum tau ua raws.
- Kev sib cuag nrog daim tawv nqaij lossis nqus pa ntawm nws cov vapors tuaj yeem ua rau khaus thiab puas rau tib neeg lub cev, thiab kev sib cuag ncaj qha thiab nqus pa yuav tsum zam thaum ua haujlwm hauv chav kuaj.
- Thaum muaj kev sib cuag lossis nqus pa, yaug qhov chaw raug mob tam sim nrog dej huv thiab nrhiav kev pab kho mob.
- Thaum khaws cia thiab tuav, cov khoom sib xyaw yuav tsum muab khaws cia rau hauv lub thawv airtight, kom deb ntawm hluav taws thiab oxygen, kom tsis txhob muaj hluav taws kub thiab tawg.
