Taw qhia
M-chlorobenzene yog ib qho organic compound.
Zoo:
M-chlorobenzene qhov muag yog xim tsis muaj kob crystalline lossis crystalline hmoov nrog tshwj xeeb xoob thiab tshuaj tua kab. Nws yuav luag insoluble hauv dej tab sis soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether. Nws yog ruaj khov ntawm chav tsev kub, tab sis yog yooj yim decomposed los ntawm lub teeb.
Siv:
M-chlorobenzene yog dav siv nyob rau hauv kev ua liaj ua teb thiab horticulture. Nws feem ntau yog siv los ua tshuaj tua kab mob thiab tuaj yeem siv los tswj qee cov nroj tsuag thiab cov qoob loo uas ua siab ntev rau kev tswj cov nroj tsuag. M-chlorobenzene kuj tseem siv tau rau tshuaj tua kab thiab npauj tswj cov ntoo.
Txoj kev:
M-chlorobenzene feem ntau yog npaj los ntawm chlorination ntawm nitrobenzene. Txoj kev npaj tshwj xeeb tuaj yeem ua kom yaj nitrobenzene hauv dilute hydrochloric acid, thiab tom qab ntawd ntxiv ferrous chloride los ua m-chlorobenzene qhov muag.
Cov ntaub ntawv kev nyab xeeb:
M-chlorobenzene muaj qee yam toxicity thiab yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb thaum siv. Ntev mus ntev los yog nqus tau pa tuaj yeem ua rau tib neeg noj qab haus huv, nrog rau kev khaus ntawm daim tawv nqaij thiab qhov muag, thiab ua rau lub hauv paus paj hlwb thiab ua pa. Thaum siv, yuav tsum tau saib xyuas kom hnav cov hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg kom tsis txhob muaj kev sib cuag nrog cov tawv nqaij thiab nqus cov plua plav. Thaum tuav m-chlorobenzene, nws yuav tsum tau khaws cia kom deb ntawm qhov qhib nplaim taws thiab kub kub kom tsis txhob muaj kev phom sij ntawm kev sib tsoo thiab tawg. Cov tshuaj no kuj yuav tsum tau muab khaws cia kom zoo thiab muab pov tseg kom tsis txhob muaj kev sib kis ntawm ib puag ncig. Ua ntej siv m-chlorobenzene, koj yuav tsum nkag siab thiab ua raws li cov txheej txheem kev nyab xeeb tsim nyog thiab cov cai.
