Hoʻolauna

ʻO 4-Bromo-3-fluorotoluene he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

4-Bromo-3-fluorotoluene he wai waihoʻoluʻu ʻole me ke apo benzene a me ka bromine a me ka fluorine substituent. He ʻala ʻala ma ka lumi wela. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

 

E hoʻohana:

ʻO 4-Bromo-3-fluorotoluene he mea koʻikoʻi koʻikoʻi i ka synthesis organik. Hoʻohana maʻamau ia i ke kahua o nā mea, no ka laʻana no ka synthesis o nā polymers me nā waiwai kūikawā.

 

Hanana:

Loaʻa ka hoʻomākaukau ʻana o 4-bromo-3-fluorotoluene ma ka hana ʻana i ka hydrogen fluoride (HF) a me ka hydrogen bromide (HBr) me nā pūhui toluene kūpono i loko o kahi ʻōnaehana pane. Pono e hoʻokō ʻia kēia pane ʻana ma ka mahana kūpono a me ke kaomi a me ka hoʻohana ʻana i kahi catalyst acidic.

 

ʻIke palekana:

ʻO 4-Bromo-3-fluorotoluene he mea ʻawaʻawa a pono e pale ʻia mai ka hoʻopili pololei ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu. I ka wā e hoʻohana ʻia ai, pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā maka aniani, a me ka pale alo. I ka lawelawe ʻana i kēia pūhui, pono e hahai ʻia nā kaʻina hana palekana lab pono a hana ʻia i loko o kahi kaiapuni maikaʻi. Pono e mālama ʻia ma kahi maloʻo, ʻoluʻolu a me ka makani maikaʻi, mamao mai nā kumu ahi a me nā lapalapa ākea. Pono e hoʻokō ʻia kekahi hana e hoʻohana ana i ka pūhui me nā lako kūpono a me nā kūlana, me ka hoʻomaʻamaʻa kūpono a me nā limahana i maopopo i ka hana palekana.
