Thiocyanate D Ammonium FDS

Ammonium thiocyanate

Thiocyanate D AMMONIUM FDS yog cov xim tsis muaj xim monoclinic flaky lossis kab crystal nrog cov mis nyuj nh4scn thiab cov molecular hnyav ntawm 76.12. Ntawm 92 degree, nws yog rhombohedral siv leadb nrog lub ntsiab lus melting ntawm 147 degree (decomple), qhov txheeb ze ntawm 1.685. Nws yog ib qho yooj yim soluble hauv dej thiab yuav muaj endothermic cov tshuaj tiv thaiv thaum ua kom yaj hauv dej. Nws yog soluble hauv dej cawv, alkali hlau hydroxide, acetone, pyridine thiab ua kua sulfur dioxide tab sis insoluble hauv chloroform. Nws cov kev daws teeb meem cov xim liab thaum muaj cov duab tshav ntuj. Thaum tau ua kom sov rau 140 degree, nws tuaj yeem tsim thaouaa thaum nws yuav tau decomposed rau hauv ammonia, hydrogen sulfide thiab carbon disulfide thiab carbon discurfide ntawm 176 degree. Nws yog yooj yim mus ua huab cua thiab yog li ntawd yuav tsum tau muab ntim nrog rho tawm los ntawm acid. Txoj kev ntau lawm: Muaj cov pa roj carbon disulfide thiab ammonia hauv cov reactor reactor hnov ​​rau 20 teev ntawm qhov kub ntawm 30 degree kom tau nws; Hloov pauv, muaj cov hmoov uas sulphur, cov tshuaj pleev cov sodium cyanide thiab cov tshuaj tua hluav taws kub ua rau muaj qhov kub thiab txias kom tau txais cov khoom kawg. Lub hom phiaj tseem ceeb: nws tuaj yeem siv ua polymerization catalysts rau cov neeg sawv cev organic, tshuaj tua kab mob xws li rau kev txiav txim siab mercury, nyiaj ntxiv rau cov kab hlau. Nws tseem siv tau rau kev tsim cov thiocyanate thiab thiocyanate complex ntsev. Nws tseem muaj qee qhov muaj peev xwm dissolving rau nyiaj halide. Nws cov kev daws teeb meem kuj tseem muaj peev xwm ntawm cov gelatin. Nws kuj tseem siv tau ua yees duab kua thiab golden xim txuam ntawm cov ntawv luam ntawv, luam ntawv ntawm paj rwb thiab hlau pickling.
