Tom ntej: Sodium Thiocyanate CAS 540-72-7
Sodium thiocyanate yog cov xim tsis muaj xim uas muaj 2 feem ntawm cov dej siv lead ua. Thaum 30.4 ℃, nws poob nws cov dej siv lead ua thiab ua anhydrous sodium thiocyanate, uas yog soluble hauv dej thiab ethanol. Nws yog tsim los ntawm azeotropic distillation ntawm sodium cyanide thiab sulfur slurry nyob rau hauv kev lag luam, thiab yog ib qho ntawm cov khoom purification ntawm coke cub roj hauv coking nroj tsuag. Nws yog tsim los ntawm cov kua pov tseg ntawm anthraquinone disulfonic acid txoj kev.

Sodium thiocyanate tuaj yeem siv los ua cov tshuaj analytical reagent, xws li rau kev txiav txim siab ntawm niobium hauv hlau thiab tsim cov organic thiocyanates rau nyiaj, tooj liab, thiab hlau. Sodium thiocyanate kuj tuaj yeem siv los ua cov kuab tshuaj rau kev kos duab polyacrylonitrile fibers, xim xim ua tus neeg saib xyuas, qee cov nroj tsuag defoliants, thiab tshav dav hlau txoj kev herbicide
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob customized.
