Hoʻolauna
ʻO ka 3,5-difluorobenzaldehyde he hui lāʻau me ke ʻano kemika C7H4F2O. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:
Nā waiwai: 3,5-difluorobenzaldehyde he kala ʻole i ka paʻa melemele māmā me kahi ʻala phenone kūikawā. He 1.383g/cm³ kona mānoanoa, he 48-52°C, a he 176-177°C. ʻO 3,5-difluorobenzaldehyde ka mea hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether, a me benzene.
Hoʻohana: 3,5-difluorobenzaldehyde ka mea maʻamau ma ke ʻano he mea waena i ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā ʻano mea hoʻohui i loko o ka fluorine, ʻoi aku hoʻi no nā hopena kemika e hoʻokomo i nā ʻātoma fluorine i loko o nā molekala. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he synthetic intermediate no nā lāʻau lapaʻau, pesticides a me nā dyes.
ʻano hoʻomākaukau: hiki ke loaʻa ke ʻano hoʻomākaukau o 3,5-difluorobenzaldehyde ma ka hana ʻana i ka 3,5-difluorobenzyl methanol me kahi reagent aldehyde acid (e like me ka trichloroformic acid, etc.). Hiki i nā ʻano hana synthetic kikoʻī ke kuhikuhi i ka Organic Synthesis Handbook a me nā palapala pili.
ʻIke palekana: ʻO 3,5-difluorobenzaldehyde he mea kemika a pono e hoʻohana pono ʻia. He mea hoʻonāukiuki a ʻino a hiki ke hōʻeha i ka maka, ka ʻili a me ka ʻōnaehana hanu. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā maka aniani, nā mīkina lima a me nā pale maka i ka wā e hoʻohana ai. E hahai i nā hana palekana hale hana a mālama, mālama a hoʻolei pono i ka pūhui. Inā loaʻa ka pilikia a i ʻole ka ʻai ʻana, e ʻimi koke i ka lāʻau lapaʻau a hāʻawi i ka ʻike kūpono i ke kauka.
