Xwm:
NH4SCN Tshuaj lom neeg lub npe ammonium thiocyanate, tsis muaj xim nplooj ib yam li lossis tas lawm. MP yog li 149 degree; dl. 305. Yooj yim rau DeliquesT thiab soluble hauv dej, nws cov kua aqueous tig ntshav daws, thiab tsis muaj cov tshuaj tiv thaiv ntawm cov ntsev. Soluble hauv ethanol, soluble hauv methanol thiab acetone, insoluble hauv chloroform thiab ethyl acetate.
Thaum rhuab rau 200-300 degree, nws decomposes rau ammonia, carbon disulfide, thiab hydrogen sulfide. Reacts tsaus nti nrog cov hmoov txhuas, chloride, nitric acid, thiab lwm yam tshuaj. Flammable, tab sis tsis yooj yim ignited. Nws tuaj yeem tsim cov roj lom rau thaum raug hluav taws.
Kev npaj txoj kev ntawm NH4SCN tshuaj lom neeg npe Ammonium thiocyanate:
Lub siab synthesis cov tshuaj ntawm carbon disulfide thiab ammonia hydrosulfide, uas yog tom qab ntawd decomposed rau hauv hydrogen sulfide los ntawm desulfurizes los ntawm desulfurization los ntawm kev ua haujlwm thiab evaporation. Cov kev daws teeb meem yog kev lim dej thiab sib cais kom tau txais cov khoom. Lwm txoj kev xaiv, cov leej fajrfur tuaj yeem raug cuam tshuam nrog sodium cyanide los tsim sodium thiocyanate, uas tuaj yeem yog decomposed nrog ammonium chloride los tsim ammonium hydrosulfite.
