Hoʻolauna

ʻO ka trifluoromethylbenzoic acid he mea hoʻohuihui.

 

Loaʻa i ka hui nā waiwai penei:

He paʻa keʻokeʻo keʻokeʻo keʻokeʻo me ka ʻala ʻala ikaika.

Paʻa ma ka lumi wela, akā decompose i nā wela kiʻekiʻe.

Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ether a me nā ʻawaʻawa, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

 

ʻO nā hoʻohana nui o ka trifluoromethylbenzoic acid ka:

Ma ke ʻano he reagent hopena i ka synthesis organik, ʻoi aku ka nui o ka synthesis o nā pūhui ʻala, he hana koʻikoʻi ia.

He mea hoʻohui koʻikoʻi i kekahi mau polymers, nā uhi a me nā mea hoʻopili.

 

Hiki ke hana ʻia ka hoʻomākaukau ʻana o ka trifluoromethylbenzoic acid e nā ʻano hana aʻe:

Hoʻopili ʻia ka waikawa Benzoic me ka trifluoromethanesulfonic acid e loaʻa ai ka trifluoromethylbenzoic acid.

Hoʻopili ʻia ka Phenylmethyl ketone e ka hopena me ka trifluoromethanesulfonic acid.

 

He mea hoʻonāukiuki ka pūpū a pono e paleʻia mai ka piliʻana me kaʻili a me nā maka.

Hōʻalo i ka hanu ʻana i ka lepo, uahu, a i ʻole ke kinoea mai ia mea.

Pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima pale, nā maka aniani a me nā masks kinoea i ka wā e hoʻohana ai.

E hoʻohana a mālama i kahi wahi hoʻoluʻu maikaʻi.
