Isingeniso

I-Trifluoromethylbenzonitrile. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

I-Trifluoromethylbenzonitrile iwuketshezi olungenambala olunephunga elimnandi. Ayiminyene futhi ayincibiliki emanzini kodwa iyancibilika ezincibilikisini eziningi eziphilayo. Iyazinzile ezingeni lokushisa legumbi kodwa ingase ibole lapho ichayeke ekushiseni.

 

Sebenzisa:

I-Trifluoromethylbenzonitrile ingasetshenziswa njengendawo ephakathi ku-organic synthesis. Emkhakheni wezibulala-zinambuzane, ingasetshenziswa ekuhlanganiseni ama-insecticides nama-herbicides. Ingasetshenziswa futhi ekulungiseleleni ama-polymers asebenza kahle kakhulu nezinto zikagesi.

 

Indlela:

Ukulungiswa kwe-trifluoromethylbenzonitrile ngokuvamile kufinyelelwa ngokwethula iqembu le-trifluoromethyl ku-molecule ye-benzonitrile ekuphenduleni. Kungase kube nezinhlobonhlobo zezindlela ezithile zokuhlanganisa, njengokusabela kwe-cyano compounds ne-trifluoromethyl compounds, noma ukusabela kwe-trifluoromethylation ye-benzonitrile.

 

Ulwazi Lokuphepha:

I-Trifluoromethylbenzonitrile iyacasula futhi yenza ukugqwala lapho igxile kakhulu futhi ingase ibangele ukucasuka noma ukulimala esikhumbeni, emehlweni, nasendleleni yokuphefumula lapho ithintwa. Kufanele kuqashelwe uma usebenzisa, njengokugqoka amagilavu ​​okuzivikela afanelekile nezibuko. Kufanele futhi isetshenziswe endaweni enomoya omuhle ukuze kugwenywe ukuhogela umhwamuko. Lapho uphatha futhi ugcina, izinqubo zokusebenza zokuphepha kufanele zilandelwe futhi zigcinwe kude nemithombo yomlilo neyokushisa. Uma ukuvuza kwenzeka, kufanele kuhlanzwe futhi kulashwe kusenesikhathi ukuze kugwenywe ukungena emanzini nasezintanjeni zendle.
