Ib, Description
Potassium ferrocyanide trihyrate, tseem hu ua poov tshuaj hexacyanoferrate trihydrate, muaj cov mis mos molecular ntawm K4Fe (CN) 6.3 (H2O) thiab yog cov khoom siv dav siv tshuaj. Nws yog tsuas yog siv nyob rau hauv kev tsim cov pigments, dyeing thiab oxidation pab, poov tshuaj cyanide, explosives, tshav kub kho steel, lithography, carving, thiab lwm yam.
Cov txheej txheem kev lag luam ntawm cov poov tshuaj ferrocyanide hauv Suav teb, txawm tias txawv, yog qhov tseem ceeb tib yam li cov kev hloov pauv ntawm cov poov tshuaj ferrocyanide.
Muaj ntau yam tsis zoo, xws li cov txheej txheem ntev thiab nkim sij hawm, nyob rau hauv txoj kev no, thiab yog tias peb tuaj yeem daws qhov teeb meem ntawm kev tswj cov txheej txheem, Los ntawm kev siv lub teeb roj hydrolysis los tsim cov alkali hlau lossis alkaline ntiaj teb hlau cyanide cov cuab yeej, nws muaj peev xwm ua tau. ua kom tiav cov txheej txheem ncaj qha tsim cov poov tshuaj xanthate los ntawm potassium cyanide thiab ferrous sulfate los yog ntxiv txhim kho cov txheej txheem tam sim no.
Nrog rau kev siv ntau ntxiv ntawm potassium ferrocyanide trihyrate nyob rau hauv ntau qhov kev lag luam hauv Suav teb, vim nws qhov tshwj xeeb zoo, nws yuav muaj qhov kev thov dav dav hauv cov txheej txheem kev txhim kho yav tom ntej.
2, Kev thov
Potassium ferrocyanide trihyrate cas 14459-95-1 siv rau hauv kev tsim cov pigments, luam ntawv thiab dyeing oxidation pab, xim, inks, poov tshuaj liab ntshav ntsev, explosives, thiab tshuaj reagents,
Potassium ferrocyanide trihyrate kuj tseem siv hauv kev lag luam xws li kev kho cua sov steel, lithography, carving, thiab kws tshuaj.
Nws cov khoom noj khoom haus additive yog tsuas yog siv los ua anticaking agents rau lub rooj ntsev.
3, Cia tej yam kev mob
1. Muab ntim rau hauv chav tsev kub thiab tiv thaiv lub teeb, cua, thiab qhuav
2. Nws tsis raug tso cai khaws cia thiab thauj ua ke nrog cov kua qaub, alkalis, hlau ntsev, thiab cov khoom noj khoom haus.
4, Kev ruaj ntseg
1. ruaj khov ntawm chav tsev kub thiab siab
2. Cov khoom siv kom tsis txhob muaj: oxide acids Soluble hauv dej; insoluble hauv ethanol, ether, methyl acetate, thiab kua ammonia. Tshav kub rau 70 degree thiab poob dej los ntawm crystallization. Thaum kub kub heev, nws decomposes tso cov pa nitrogen thiab tsim cov poov tshuaj cyanide thiab hlau carbide. Nws cov tshuaj aqueous decomposes rau hauv hlau hydroxide thaum raug lub teeb. Thaum ntsib halogen peroxides, lawv tsim cov ntshav liab poov tshuaj ntsev. Thaum ntsib nitric acid, nws thawj zaug tsim cov ntshav liab poov tshuaj ntsev, tom qab ntawd los ntawm kev tsim nitrosoiron cyanide.
3. Cov khoom no tsis muaj tshuaj lom, tab sis nws cov khoom siv raw, cyanide, thiab cyanide ua los ntawm cov khoom thermal decomposition yog cov tshuaj lom heev. Kev kho thiab tiv thaiv kev ntsuas rau cyanide generated thaum lub sij hawm tsim los yog decomposition
