Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate waa crystal aan midab lahayn oo ka kooban 2 qaybood oo biyo crystal ah. Markay tahay 30.4 ℃, waxay lumisaa biyihii crystal waxayna noqotaa sodium thiocyanate anhydrous, taas oo ku milma biyaha iyo ethanol. Waxa soo saara azeotropic distillation of sodium cyanide iyo slurry sulfur ee warshadaha, waana mid ka mid ah alaabta sifaynta ee gaaska foornada kookaha ee dhirta coking. Waxaa laga soo saaraa dareeraha qashinka ee habka disulfonic acid anthraquinone.

Sodium thiocyanate waxaa loo isticmaali karaa sidii falanqeyn falanqeyn ah, sida go'aaminta niobium ee birta iyo soo saarista thiocyanate organic ah lacag, naxaas, iyo birta. Sodium thiocyanate sidoo kale waxaa loo isticmaali karaa sida dareere loogu sawiro fiilooyinka polyacrylonitrile, wakiilka filimaanta midabka, qaar ka mid ah dhirta defoliants, iyo herbicide wadada garoonka diyaaradaha.
Caadi ahaan waxaa lagu buuxiyaa 25kg/durbaan, sidoo kale waxaa la samayn karaa xirmo habaysan.
