Hoʻolauna
ʻO ka 3,4-difluorotoluene he mea hoʻohuihui mea ola me ke ʻano kemika C7H6F2. He wai kala ʻole me kahi ʻala ʻala kūikawā. Eia ka wehewehe kikoʻī o ke ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana o 3,4-difluorotoluene:
ʻAno:
-Nani: wai kala ʻole
-ʻono: ʻala ʻala kūikawā
-Pila paila: 96-97 ° C
-Ka mānoanoa: 1.145g/cm³
-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik
E hoʻohana:
Hiki ke hoʻohana ʻia -3,4-difluorotoluene ma ke ʻano he waena koʻikoʻi i ka synthesis organik.
-Hiki ke hoʻohana ʻia e synthesize i nā lāʻau lapaʻau, nā mea hoʻonaninani, nā pesticides a me nā mea ʻē aʻe.
-Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā mea uila.
Hanana:
ʻO -3,4-difluorotoluene he nui nā ʻano hoʻomākaukau, ʻo ka mea maʻamau i loaʻa ma ka hydrogenation reduction reaction o p-nitrotoluene. ʻO nā ʻanuʻu kikoʻī:
1. ʻO ka mua, hana ka P-nitrotoluene me ka hao nui diammonium sulfate e loaʻa ai ka p-nitrotoluene hao diammonium paʻakai.
2. Hoʻohui ʻia ka hydrogen, a ua kau ʻia ka paʻakai diammonium hao p-nitrotoluene i ka hopena hoʻemi i ke alo o kahi mea hoʻoheheʻe hao.
3. ʻO ka hope, ua hoʻomaʻemaʻe ʻia ka 3,4-difluorotoluene e ka distillation.
ʻIke palekana:
ʻO ka -3,4-difluorotoluene i manaʻo ʻia he palekana ma lalo o nā kūlana maʻamau o ka hoʻohana. Eia nō naʻe, pono e hoʻokō i nā kaʻina hana palekana kūpono.
-He wai wela ia a pono e pale i ka pili ʻana me ke ahi a me ka wela kiʻekiʻe.
-ʻO nā mīkina lima pale kūpono, nā maka aniani a me nā lole pale e ʻōlelo ʻia no ka hoʻohana ʻana a me ka lawelawe ʻana.
-E mālama i ka meaʻai, ka wai a me nā keiki.
-Inā loaʻa ka ʻike a i ʻole ka ʻai ʻana ʻole, e ʻimi koke i ke kōkua olakino a hōʻike i ka lepili huahana a i ʻole ka pahu i kahi mea mālama ola.
