Intshayelelo emfutshane
I-4-Chloro-2-fluorobenzoic acid i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
I-4-Chloro-2-fluorobenzoic acid yikristale eyomeleleyo, edla ngokungenambala okanye iikristale ezityheli. Ayinakuguquka kwiqondo lobushushu begumbi. Inencasa enevumba elimnandi kwaye inokunyibilika kwizinyibilikisi zendalo ezifana ne-methanol, i-ethanol, i-methylene chloride, njl.
Sebenzisa:
I-4-Chloro-2-fluorobenzoic acid inoluhlu olubanzi lwezicelo kwishishini lemichiza. Ihlala isetyenziswa njengesixhobo sokuqala okanye esiphakathi kwi-organic synthesis. Isenokusetyenziswa njenge-feedstock ye-catalysts kunye nemathiriyeli ye-elektroniki.
Indlela:
I-4-Chloro-2-fluorobenzoic acid inokufumaneka nge-chlorination ye-p-fluorobenzoic acid. Ngokuqhelekileyo, i-hydrogen chloride okanye i-chlorous acid ingaphendulwa kunye ne-thionyl chloride okanye i-sulfinyl chloride phantsi kweemeko ze-acidic, ilandelwa yimpendulo kunye ne-hydrogen fluoride ukufumana i-4-chloro-2-fluorobenzoic acid.
Ulwazi ngoKhuseleko:
Ezi zilumkiso zilandelayo zokhuseleko kufuneka zithathwe xa uphatha i-4-chloro-2-fluorobenzoic acid: ugweme ukudibanisa nesikhumba kunye namehlo, kwaye ubeke ingqalelo kumanyathelo okukhusela afana nokunxiba iiglasi zokukhusela kunye neiglavu. Kufuneka lwenziwe kwindawo engena umoya ukuze kuthintelwe ukuphefumla okanye ukuginya. Kuphephe ukudibana nezinto ezinokutsha kwaye uzigcine kude namadangatye avulekileyo okanye amaqondo obushushu aphezulu. Kufuneka itywinwe ngokuqinileyo xa isetyenziswa okanye igcinwe kwaye kude neeasidi, iziseko, kunye nee-oxidants. Xa kukho ukuvuza, amanyathelo angxamisekileyo afanelekileyo kufuneka athathwe, njengokufunxa i-liquid nge-desiccant okanye ukuyicoca nge-adsorbent yeekhemikhali ezifanelekileyo.
