Hoʻolauna

ʻO 2,5-Difluorotoluene he mea hoʻohuihui.

 

ʻAno maikaʻi:

ʻO 2,5-Difluorotoluene he wai kala ʻole me ka ʻala benzene ʻono. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me benzene. ʻO 2,5-Difluorotoluene paʻa i ka ea, akā e hoʻoheheʻe mālie ke ʻike ʻia i ka mālamalama.

 

E hoʻohana:

Loaʻa i ka 2,5-Difluorotoluene nā ʻano hana ʻenehana. ʻO ka lua, hoʻohana ʻia ia e like me ka fluorination reagent i ka organik synthesis, hiki ke hoʻokomo i nā atom fluorine i loko o nā molekala, hoʻonui i ka hana o nā molekala a hoʻololi i nā waiwai kemika. Ma muli o kāna mau waiwai kino a me nā kemika kūikawā, hiki ke hoʻohana ʻia ka 2,5-difluorotoluene ma ke ʻano he mea hoʻoheheʻe a me ka hoʻoiho.

 

Hanana:

Loaʻa ka synthesis o 2,5-difluorotoluene ma ka hopena fluorinated. ʻO nā ʻano kikoʻī e pili ana i ka pane ʻana o benzene me ke kinoea fluorine i mua o kahi mea hana fluorinating ikaika, a i ʻole ka hoʻohana ʻana i ka bisulfate fluoric acid ma ke ʻano he kumu fluorine no nā hopena fluorinated.

 

ʻIke palekana:

I ka hoʻohana ʻana a me ka mālama ʻana i ka 2,5-difluorotoluene, pono e hoʻomaopopo ʻia kēia: he mea hoʻoheheʻe organik, volatile a pono e pale ʻia mai ka inhalation a me ka pili ʻana me ka ʻili. ʻO ka lua, he mea hoʻonāukiuki i ka maka, ka ʻili a me ka ʻōpū hanu, a pono e mālama ʻia nā mea pale kūpono, e like me ke komo ʻana i nā aniani pale, ke komo ʻana i nā lole pale a me ka hoʻohana ʻana i nā mīkina lima pale. Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale i ka hoʻopili ʻana me nā kumu ahi e pale ai i nā kūlana i manaʻo ʻole ʻia e like me ke ahi a me ka pahū.
