Mawu Oyamba
2-Chloro-4-fluorotoluene. Makhalidwe ake ndi awa:
1. Maonekedwe: 2-chloro-4-fluorotoluene ndi madzi opanda mtundu kapena kristalo woyera.
2. Kusungunuka: kusungunuka mu zosungunulira zopanda polar, monga ethanol, acetone ndi ether, zosasungunuka m'madzi.
Ntchito zake zazikulu ndi izi:
1. Mankhwala apakati: 2-chloro-4-fluorotoluene amagwira ntchito yofunika kwambiri pakupanga organic monga chinthu chofunikira kwambiri.
2. Mankhwala ophera tizilombo: Amagwiritsidwanso ntchito ngati imodzi mwazinthu zopangira mankhwala. Mwachitsanzo, angagwiritsidwe ntchito popanga mankhwala ophera tizilombo ndi herbicides.
Pali njira zingapo zokonzekera 2-chloro-4-fluorotoluene, imodzi yomwe imagwiritsidwa ntchito ndi fluorination ndi chlorination. Kawirikawiri, 2-chloro-4-fluorotoluene ikhoza kupezedwa potsirizira pake ndi fluorinating ndi fluorinating agent (monga hydrogen fluoride) pa 2-chlorotoluene ndiyeno ndi chlorination ndi chlorinating agent (monga aluminium kolorayidi).
Zambiri zachitetezo: 2-chloro-4-fluorotoluene nthawi zambiri imakhala yotetezeka pakagwiritsidwe ntchito bwino
1. Kawopsedwe: 2-chloro-4-fluorotoluene ikhoza kuyambitsa ngozi zina paumoyo. Kuwonekera kwa nthawi yayitali kapena kupuma movutikira kungayambitse kuwonongeka kwa dongosolo lamanjenje, chiwindi, ndi impso.
2. Kuphulika: 2-chloro-4-fluorotoluene ndi madzi oyaka, ndipo nthunzi yake imatha kupanga chisakanizo choyaka. Iyenera kusungidwa kutali ndi malawi otseguka ndi magwero a kutentha, ndi kusungidwa pamalo ozizira ndi mpweya wabwino.
3. Chitetezo chaumwini: Pogwira 2-chloro-4-fluorotoluene, zipangizo zodzitetezera zoyenera monga magolovesi, zovala zodzitetezera, ndi zovala zodzitetezera ziyenera kuvalidwa.
