Hoʻolauna
ʻO ka 3,4-difluorobenzotrifluoride he mea hoʻohui kino me ke ʻano kemika C7H2F5. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: 3,4-difluorobenzotrifluoride he wai kala ʻole.
-Ka helu heheʻe:-35 ° C
-Pila paila: 114 ° C
-Ka mānoanoa: 1.52g/cm³
-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik, e like me ka ethanol, ether a me benzene.
E hoʻohana:
Hoʻohana pinepine ʻia ka -3,4-difluorobenzotrifluoride ma ke ʻano he mea hoʻoheheʻe no nā hopena synthesis organik. ʻO kona solubility kiʻekiʻe a me ke ʻano anhydrous e hoʻohana nui ia i ka synthesis organik.
-Hiki ke hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau a me ka mea hoʻomaʻemaʻe.
Hanana:
-3,4-difluorobenzotrifluoride hiki ke loaʻa ma ka reacting 3,4-difluorophenyl hydrogen sulfide me barium trifluoride. ʻO ke ʻano o ka hopena ma ke alo o ka magnesium chloride, hoʻomehana ʻia no kekahi mau hola, a laila mālama i ka hopena waena me ka waiʻona.
ʻIke palekana:
ʻO -3,4-difluorobenzotrifluoride he mea hoʻoheheʻe organik, a pono e pale ʻia ka inhalation o kona mahu.
-E hoʻohana i nā lako pale pilikino kūpono e like me nā maka aniani, nā mīkina lima a me nā lole pale ke hoʻohana ʻia.
- Hiki ke hoʻopōʻino i ke olakino ka lōʻihi a i ʻole ka hoʻolaha nui ʻana a hiki i ka maka, ka hanu a me ka ʻili.
- ma ka hoʻohana ʻana a me ka mālama ʻana pono e hoʻolohe i nā hana pale ahi a pahū, e pale i ka pili ʻana me nā oxidants ikaika.
-Inā paʻi ʻole ʻoe i kou mau maka a pili paha i kou ʻili, holoi koke me ka wai nui a ʻimi i ke kōkua olakino.
