Umthengisi weBenzoyl Hydroximic Acid eMzantsi Afrika

Yintoni iBenzoyl Hydroximic Acid?

I-Benzoyl hydroximic acid (BHA, i-benzhydroxamic acid) yeyona acid ilula kakhulu enevumba elimnandi, equlathe indandatho ye-phenyl (benzene) eqhotyoshelwe ngqo kwiqela elisebenzayo le-hydroxamic acid (C(=O)NHOH). Yimodeli eqokelelweyo efundwe kakuhle kuthotho lwe-hydroxamic acid, esetyenziswa kakhulu kwizicelo zophando ngenxa yobunyulu bayo obuphezulu kunye nesakhiwo sayo se-molecular esichaziweyo, kwaye isetyenziswa ngakumbi njengomqokeleli we-oxide mineral flotation apho iprofayili yayo yokukhetha inika iingenelo ngaphezu kwe-alkyl (uhlobo lwe-fatty acid) hydroxamic acids.

Ukukhetha kunye nokusebenza

I-BHA ikhetha kakhulu i-cassiterite (SnO₂), i-wolframite ((Fe,Mn)WO₄), kunye neeminerali ze-oxide ezinqabileyo zomhlaba, zenza ii-complexes ze-ring chelate ezizinzileyo kakhulu kwiindawo zazo ezityebileyo ngesinyithi ngelixa zibonisa ukufunxwa okuncinci kwi-quartz kunye ne-gangue ezininzi ze-silicate. Kwi-flotation ye-tin kunye ne-tungsten, i-BHA inika ukubuyiswa okuhle kweminerali ye-oxide ekujoliswe kuyo kunye nokwaliwa okugqwesileyo kwe-gangue, kunciphisa iimfuno zokucoca okuxineneyo. Ukucoceka kwayo okuphezulu kwenza ukuba ifaneleke kwizicelo zophando apho ubumsulwa bokuqokelela bufuneka khona kwizifundo ze-mechanistic.

Iinkcukacha zoNikezelo

I-Terracore Chemicals inika i-benzoyl hydroximic acid kwiingxowa ezingama-25 kg kwiiklasi zobugcisa nezophando. Sicebisa ngeendlela ezifanelekileyo zokulungisa imeko (ubushushu, i-pH, i-ethanol/i-co-solvent yamanzi yokunyibilikisa) kunye nokukhetha okuthelekisayo kunye nee-salicyl kunye nee-alkyl hydroximic acid collectors kwiindibano ezithile ze-oxide mineral.
