Taw qhia

 

Zoo:

4-Fluoro-2-nitrotoluene yog xim tsis muaj xim rau daj crystalline hmoov uas yog khoom nyob rau hauv chav tsev kub. Nws muaj cov ntxhiab tsw muaj zog thiab yog insoluble hauv dej, tab sis nws yooj yim soluble hauv cov kuab tshuaj organic xws li ethanol thiab ketones.

 

Siv:

 

Txoj kev:

Txoj kev npaj ntawm 4-fluoro-2-nitrotoluene tuaj yeem tau txais los ntawm fluorination ntawm p-nitrotoluene. Tshwj xeeb, hydrogen fluoride los yog sodium fluoride tuaj yeem siv los ua cov tshuaj nitrotoluene hauv cov kuab tshuaj organic lossis cov tshuaj tiv thaiv kab mob thiab ntawm qhov kub thiab txias.

 

Cov ntaub ntawv kev nyab xeeb:

Muaj qee yam kev ntsuas kev nyab xeeb uas yuav tsum tau ua thaum siv 4-fluoro-2-nitrotoluene. Nws yog ib qho organic compound uas yog me ntsis lom thiab irritating. Kev nqus pa ntawm nws cov pa roj lossis plua plav yuav tsum tau zam thaum lub sijhawm ua haujlwm thiab kev ua pa zoo yuav tsum tau ua kom ntseeg tau. Yaug tam sim ntawd tom qab sib cuag nrog daim tawv nqaij lossis ob lub qhov muag nrog dej kom ntau thiab nrhiav kev kho mob. Thaum khaws cia thiab thauj khoom, kev sib cuag nrog cov khoom siv hluav taws xob yuav tsum zam, thiab cov thawv ntim khoom yuav tsum tau muab kaw kom nruj kom deb ntawm qhov hluav taws kub thiab cua sov.
