Chiyambi chachidule
4-Chloro-2-fluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
4-Chloro-2-fluorobenzoic acid ndi makristalo olimba, omwe nthawi zambiri amakhala opanda mtundu kapena achikasu. Simasinthasintha kutentha kwapakati. Ili ndi kununkhira konunkhira ndipo imatha kusungunuka mu zosungunulira za organic monga methanol, ethanol, methylene chloride, etc.
Gwiritsani ntchito:
4-Chloro-2-fluorobenzoic acid ili ndi ntchito zambiri m'makampani opanga mankhwala. Nthawi zambiri amagwiritsidwa ntchito ngati zoyambira kapena zapakatikati mu kaphatikizidwe ka organic. Itha kugwiritsidwanso ntchito ngati chakudya chazothandizira komanso zida zamagetsi.
Njira:
4-Chloro-2-fluorobenzoic acid imatha kupezeka ndi chlorination wa p-fluorobenzoic acid. Nthawi zambiri, hydrogen chloride kapena chlorous acid imatha kuchitidwa ndi thionyl chloride kapena sulfinyl chloride pansi pa acidic, kutsatiridwa ndi hydrogen fluoride kupeza 4-chloro-2-fluorobenzoic acid.
Zambiri Zachitetezo:
Njira zodzitetezera zotsatirazi ziyenera kutsatiridwa pogwira 4-chloro-2-fluorobenzoic acid: pewani kukhudzana ndi khungu ndi maso, ndipo samalani ndi njira zodzitetezera monga kuvala magalasi oteteza ndi magolovesi. Ayenera kuchitidwa pamalo olowera mpweya wabwino kuti asatulukemo kapena kumeza. Pewani kukhudzana ndi zinthu zoyaka ndipo pewani ndi moto wotseguka kapena kutentha kwambiri. Iyenera kusindikizidwa mwamphamvu ikagwiritsidwa ntchito kapena kusungidwa komanso kutali ndi ma acid, maziko, ndi ma oxidants. Pakatuluka, njira zoyenera zadzidzidzi ziyenera kuchitidwa, monga kuyamwa madzi ndi desiccant kapena kuyeretsa ndi mankhwala oyenera adsorbent.
