Intshayelelo
Umgangatho:
I-4-Fluoro-2-nitrotoluene ngumgubo wekristale ongenambala ukuya kumthubi oqinileyo kwiqondo lobushushu begumbi. Inevumba elinamandla kwaye ayinyibiliki emanzini, kodwa inyibilika ngokulula kwizinyibilikisi zendalo ezifana ne-ethanol kunye neeketones.
Sebenzisa:
Indlela:
Indlela yokulungiselela i-4-fluoro-2-nitrotoluene inokufumaneka nge-fluorination ye-p-nitrotoluene. Ngokukodwa, i-hydrogen fluoride okanye i-sodium fluoride ingasetyenziselwa ukusabela kunye ne-nitrotoluene kwii-solvents eziphilayo okanye iinkqubo zokuphendula kunye nokushisa okufanelekileyo kunye noxinzelelo.
Ulwazi ngoKhuseleko:
Kukho imilinganiselo ethile yokhuseleko ekufuneka ilandelwe xa usebenzisa i-4-fluoro-2-nitrotoluene. Yikhompawundi ephilayo enetyhefu noko kwaye iyacaphukisa. Ukuphefumla iigesi zayo okanye uthuli kufuneka kugwenywe ngexesha lokusebenza kwaye iimeko ezifanelekileyo zokungenisa umoya kufuneka ziqinisekiswe. Hlamba ngokukhawuleza emva kokudibana nolusu okanye amehlo ngamanzi amaninzi kwaye ufune iingcebiso zonyango. Xa ugcina kwaye uthuthwa, ukudibana nezinto ezinokutsha kufuneka kuphetshwe, kwaye izikhongozeli kufuneka zigcinwe zivaliwe ngokungqongqo kude nomlilo kunye nemithombo yobushushu.
