Umthengisi we-Ammonium Cerium Nitrate (Ceric Ammonium Nitrate) eMzantsi Afrika

Yintoni iCeric Ammonium Nitrate (CAN)?

I-Ceric ammonium nitrate (CAN), okanye i-ammonium cerium(IV) nitrate enefomula (NH₄)₂Ce(NO₃)₆, yi-crystalline oxidant ecacileyo e-orenji-bomvu esetyenziswa kakhulu kwi-organic chemistry nakwizicelo zohlalutyo. Yenye yezona oxidants ze-single-electron zilula kakhulu ezikhoyo kwimo ye-inorganic, inyibilika lula emanzini nakwi-acetonitrile, kwaye isebenza njenge-reagent ethambileyo kodwa esebenzayo phantsi kweemeko zamanzi ngaphandle kokuvelisa iimveliso ezinengxaki.

I-Oxidant yokwenziwa kwezinto eziphilayo

I-CAN isetyenziswa kakhulu kwi-organic synthesis njenge-oxidant ekhethiweyo yokususa amaqela akhuselayo, ngakumbi ii-ether ze-p-methoxybenzyl (PMB) kunye nee-esters. I-oxidizes ii-hydroquinones kwi-quinones, iqhekeza iibhondi ze-carbon-carbon kwi-1,2-diols, kwaye iququzelela i-nitration kunye ne-cyanation yeekhompawundi ze-aromatic. Ukuhambelana kwayo neentlobo ngeentlobo zamaqela asebenzayo kuyenza ibe yi-reagent ekhethwayo kwi-pharmaceutical kunye ne-fine chemical synthesis.

I-Analytical Chemistry kunye neMigangatho ePhambili

Kwikhemistri yohlalutyo, i-ceric ammonium nitrate isebenza njengomgangatho ophambili we-cerimetric titrations, inika uhlobo oluzinzileyo nolulinganiswe ngokuchanekileyo lwe-Ce(IV) olufanelekileyo ekulinganiseni ii-reducing agents. Isetyenziswa kuhlalutyo lobungakanani be-iron(II), i-hydrogen peroxide, i-oxalic acid, kunye nee-organic reducing compounds. I-reagent inikezelwa ngococeko lwe-analysis-grade kwizicelo zelebhu kulo lonke elaseMzantsi Afrika.

Ukukrola i-PCB kunye ne-Oxidation yeShishini

I-CAN isetyenziswa kwiifomyula ezikhethekileyo zokugrumba ze-PCB njengendlela eyahlukileyo endaweni ye-ferric chloride, ingakumbi ekugrumbeni iimpawu zesekethe ezincinci kakhulu. Kwi-oxidation yemizi-mveliso, iqala ii-reactions ze-radical polymerisation kwaye ithatha inxaxheba kwi-oxidative synthesis ye-conducting polymers ezifana ne-polyaniline kunye ne-polypyrrole. Ikwasetyenziswa kwiinkqubo zokubeka iifilimu ezincinci ze-cerium oxide.
