Mawu Oyamba
Trifluoromethylbenzonitrile. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
Trifluoromethylbenzonitrile ndi madzi opanda mtundu komanso onunkhira. Ndiwocheperako komanso osasungunuka m'madzi koma amasungunuka muzosungunulira zambiri. Imakhala yokhazikika potentha koma imatha kuwola ikakumana ndi kutentha.
Gwiritsani ntchito:
Trifluoromethylbenzonitrile angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic. M'munda wa mankhwala, angagwiritsidwe ntchito mu synthesis wa tizilombo ndi herbicides. Itha kugwiritsidwanso ntchito pokonzekera ma polima apamwamba kwambiri komanso zida zamagetsi.
Njira:
Kukonzekera kwa trifluoromethylbenzonitrile nthawi zambiri kumatheka poyambitsa gulu la trifluoromethyl mu molekyulu ya benzonitrile poyankha. Pakhoza kukhala njira zosiyanasiyana za kaphatikizidwe, monga momwe mankhwala a cyano amachitira ndi mankhwala a trifluoromethyl, kapena trifluoromethylation reaction ya benzonitrile.
Zambiri Zachitetezo:
Trifluoromethylbenzonitrile imakwiyitsa komanso kuwononga kwambiri ndipo imatha kuyambitsa kuyabwa kapena kuwononga khungu, maso, komanso kupuma kwapakhungu. Muyenera kusamala mukamagwiritsa ntchito, monga kuvala magolovesi oteteza ndi magalasi oyenera. Ayeneranso kugwiritsidwa ntchito pamalo olowera mpweya wabwino kuti asapume mpweya. Pogwira ndi kusunga, njira zoyendetsera chitetezo ziyenera kutsatiridwa ndikusungidwa kutali ndi moto ndi magwero otentha. Ngati kutayikira kwachitika, iyenera kutsukidwa ndikuthandizidwa munthawi yake kuti isalowe m'madzi ndi ngalande.
