Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluI-Ceric Sulfate.

Ezona mpawu:

Ubunyulu obuphezulu:I-Ceric Sulfate ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo:I-Ceric Sulfate inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweI-Ceric Sulfate iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

I-catalyst yezekhemikhali kwimizi-mveliso: I-sulfuric acid ene-cerium ephezulu, njenge-oxidant enamandla, isetyenziswa kwi-organic synthesis ukuququzelela ii-reactions ezahlukeneyo, kubandakanya i-selective oxidation ye-alcohols ukuya kwi-ketones, i-sulfonation ethe ngqo ye-methane kunye ne-trioxide sulfur ukwenza i-methanesulfonic acid, kunye ne-catalysis ye-condensation ye-2-naphthol kunye ne-aldehydes phantsi kweemeko ezingenasombululo kunye ne-microwave ukwenza i-14-aryl okanye i-14-alkyl-14H-dibenz[a,j]sulfuranthene. Ipropati yayo yokuxinana ibaluleke kakhulu phantsi kweemeko ze-asidi.

Isithambisi sePond Phosphorus: Ngenxa yeempawu zayo zeekhemikhali, i-sulfuric acid ene-cerium eninzi inokususa i-phosphate kwimizimba yamanzi ngokuna kwemvula, nto leyo eluncedo ekusombululeni ingxaki yokuphelelwa ngamandla kwamanzi emzimbeni.

Iibhetri kunye nezixhobo zamandla: I-Sulfuric acid enomxholo ophezulu we-cerium isetyenziswa njengesandulela sokulungiselela i-cerium oxide (CeO2)₂) ii-nanospheres. Ezi nanomaterials zibonisa ukusebenza kakuhle kwe-catalytic kwi-reduction reaction ye-nitric oxide (NO) kwaye zinokusetyenziswa okunokwenzeka kwimimandla yamandla kunye ne-okusingqongileyo.

Ukwenziwa kweekhemikhali okuphakathi: I-Sulfuric acid cerium(IV) sisithambisi esibalulekileyo sohlalutyo, esisetyenziswa kakhulu kwi-oxidation-reduction titrations (ezifana nokulinganisa izisombululo ze-sodium thiosulfate) ukumisela izinto ezinokungcoliswa, ezifana ne-nitrite, iodide, kunye ne-low-valent iron salts. Ikwasisixhobo esiphambili sokudibanisa ezinye iikhompawundi ze-cerium (ezifana ne-cerium dioxide).
