Intshayelelo

I-2-Chlorotrifluorotoluene yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:

 

Umgangatho:

Ukubonakala: I-2-chlorotrifluorotoluene i-liquid engenambala okanye i-crystal emhlophe.

Ubuninzi: Ubuninzi bobudlelwane buphezulu.

Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo, ezifana neealkoholi kunye ne-ethers, kwiqondo lobushushu begumbi.

 

Sebenzisa:

I-2-Chlorotrifluorotoluene isetyenziswa ngokubanzi kwi-organic synthesis kwaye ingasetyenziselwa njenge-catalyst, i-reaction intermediate okanye i-solvent.

 

Indlela:

Iindlela zokulungiselela i-2-chlorotrifluorotoluene ngokubanzi ngolu hlobo lulandelayo:

Ifunyenwe ngokusabela kwe-trifluorotoluene kunye ne-aluminium chloride, kwaye iimeko zokusabela zingqongqo.

Ukusabela kwe-trifluorotoluene ngegesi ye-chlorine kufuneka kuqhutywe kwiqondo lokushisa eliphezulu.

Inokuphinda ifumaneke ngokusabela kwe-3-fluorophenylacetic acid kunye neentsimbi ze-alkali okanye iziseko ze-organic, ilandelwa yimpendulo nge-aluminium chloride.

 

Ulwazi ngoKhuseleko:

Xa uphatha i-2-chlorotrifluorotoluene, kufuneka kuthathwe unonophelo ukuze ugweme ukudibanisa nesikhumba kunye namehlo ukuphepha ukucaphuka okanye ukubola.

Kufuneka iqhutywe kwindawo engena umoya ukuze uphephe ukuphefumla umphunga okanye uthuli.

Xa ugcina kwaye uthutha, kufuneka kuthathelwe ingqalelo ukukhusela amaqondo aphezulu kunye nemithombo yomlilo.

Xa silahla inkunkuma, kufuneka silandele imithetho nemigaqo yendalo esingqongileyo kwaye sithathe amanyathelo afanelekileyo okuyilahla.
