Mawu Oyamba
2-Fluoro-4-chlorotoluene ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera, ndi chidziwitso cha chitetezo cha mankhwalawa:
Ubwino:
2-Fluoro-4-chlorotoluene ndi madzi opanda mtundu okhala ndi kukoma kokoma kwa musky. Imasungunuka mu zosungunulira organic monga ethers ndi ma alcohols, koma osasungunuka m'madzi.
Gwiritsani ntchito:
2-Fluoro-4-chlorotoluene ndi yofunika pakati pa kaphatikizidwe ka organic. Itha kugwiritsidwanso ntchito ngati zosungunulira.
Njira:
2-Fluoro-4-chlorotoluene ikhoza kukonzedwa pochita 2,4-dichloroluene ndi hydrogen fluoride. Izi nthawi zambiri zimachitika pansi pa acidic. Choyamba, 2,4-dichloroluene ndi hydrogen fluoride amawonjezedwa ku chotengera chotengera ndipo zomwe zimachitika zimasunthidwa pa kutentha koyenera kwa nthawi. Kenako, kudzera mu distillation ndi masitepe oyeretsa, 2-fluoro-4-chlorotoluene imapezeka.
Zambiri Zachitetezo:
2-Fluoro-4-chlorotoluene imakwiyitsa komanso ikuwononga. Kukhudza khungu ndi maso kungayambitse kuyabwa ndi kutentha. Zovala zodzitetezera zoyenera, magalasi, ndi zovala zodzitetezera ziyenera kuvalidwa pozigwira ndi kuzigwiritsira ntchito. Ngati mutakoka mpweya kapena kumeza, pitani kuchipatala mwamsanga. Pankhani yosungira ndi kuyendetsa, kukhudzana ndi ma oxidizing amphamvu ndi ma asidi amphamvu kuyenera kupewedwa.
