Qhov sib txawv tseem ceeb ntawm calcium cyanide thiab calcium cyanamide yog calcium cyanide yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium cyanamide nrog carbon nyob rau hauv ib tug fused ntsev yaj, whereas calcium cyanamide yog tsim los ntawm nitrogenation ntawm calcium carbide.
Calcium cyanide thiab calcium cyanamide yog ib qho tseem ceeb ntawm cov tshuaj inorganic uas yog calcium ntsev ntawm cyanide-muaj tshuaj.
Calcium Cyanide yog dab tsi?
Calcium cyanide yog ib qho inorganic compound uas muaj cov tshuaj formula Ca(CN)2. Nws yog calcium ntsev ntawm hydrogen cyanide acid thiab tseem hu ua dub cyanide. Thaum nws nyob rau hauv daim ntawv ntshiab, calcium cyanide tshwm li cov khoom dawb, thaum cov qauv coj mus muag yog xim dub-grey. Cov tshuaj no tuaj yeem hydrolyze tau yooj yim thaum raug rau huab cua noo. Qhov no hydrolysis tso tawm hydrogen cyanide. Zoo ib yam li tag nrho lwm cov cyanide tebchaw, calcium cyanide kuj yog tshuaj lom heev.
Daim duab 01: Cov Qauv Tshuaj ntawm Calcium Cyanide Compound
Cov molar loj ntawm cov tshuaj no yog 92.1 g / mol. Cov ntxhiab ntawm calcium cyanide zoo ib yam li hydrogen cyanide. Nyob rau hauv high kub, lub tebchaw yuav undergo decomposition. Nws yog ib qho dej-soluble compound thiab tseem soluble hauv cawv thiab tsis muaj zog acids. Cov qauv siv lead ua ntawm calcium cyanide yog rhombohedric. Nws yog tshuaj lom heev tab sis tsis-flammable.
Peb tuaj yeem npaj calcium cyanide los ntawm kev kho cov hmoov calcium oxide nrog hydrocyanic acid (boiling) thaum muaj cov accelerator, xws li. ammonia lossis dej, uas tuaj yeem txo qhov poob ntawm hydrocyanic acid los ntawm polymerization.
Muaj cov kev siv tseem ceeb ntawm calcium cyanide, uas suav nrog kev lag luam mining, qhov uas nws ua haujlwm pheej yig ntawm cyanide rau ntau leaching lossis vat ua haujlwm kom tau txais cov hlau muaj txiaj ntsig, xws li. kub, nyiaj, thiab lwm yam. Qhov no yog ua los ntawm kev tsim cov kev sib koom ua ke nrog cov hlau, uas ua rau kev sib cais ntawm cov hlau los ntawm lawv cov ore.
Calcium Cyanamide yog dab tsi?
Calcium cyanamide yog ib qho inorganic compound uas muaj cov tshuaj formula CaCN2. Peb tuaj yeem muab nws lub npe calcium ntsev ntawm cyanamide anion. Nws yog ib qho tseem ceeb raws li ib tug chiv uas yog lag luam hu ua nitrolime. Cov khoom no zoo li cov khoom dawb uas feem ntau tshwm hauv cov xim grey lossis xim dub vim yog impurities. Nws yog tshuaj tsw qab.
Daim duab 02: Cov qauv tshuaj ntawm Calcium Cyanamide
Peb tuaj yeem npaj calcium cyanamide los ntawm calcium carbide. Hauv cov txheej txheem tsim khoom no, cov hmoov carbide tau kho kom sov txog li 1000 degrees Celsius siv lub tshuab hluav taws xob. Cov txheej txheem no ua rau nitrogen hauv cov qauv dhau ob peb teev. Tom qab ntawd, peb tuaj yeem txias cov khoom rau hauv qhov kub thiab txias uas tsis muaj carbide tuaj yeem ua kom zoo zoo nrog dej. Cov txheej txheem crystallizes cov khoom nyob rau hauv ib tug hexagonal siv lead ua system.
Daim duab 03: Siv Calcium Cyanamide ua Fertilizer hauv av
Muaj ntau qhov kev siv calcium cyanamide; siv nws los ua cov chiv ua liaj ua teb uas tuaj yeem tso tawm ammonia, pab tau rau kev tsim cov sodium cyanide los ntawm kev sib xyaw nrog sodium carbonate, pab tau hauv cov txheej txheem cyanide rau kev khawb kub, thiab lwm yam.
Qhov txawv ntawm Calcium Cyanide thiab Calcium Cyanamide yog dab tsi?
Calcium cyanide thiab calcium cyanamide yog cov tshuaj inorganic sib txuas. Qhov sib txawv tseem ceeb ntawm calcium cyanide thiab calcium cyanamide yog calcium cyanide yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium cyanamide nrog carbon nyob rau hauv ib tug fused ntsev yaj, whereas calcium cyanamide yog tsim los ntawm nitrogenation ntawm calcium carbide.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm calcium cyanide thiab calcium cyanamide hauv daim ntawv tabular rau ib sab sib piv.
Summary – Calcium Cyanide vs Calcium Cyanamide
Calcium cyanide yog ib qho inorganic compound uas muaj cov tshuaj formula Ca(CN)2. Calcium cyanamide yog ib qho inorganic compound uas muaj cov tshuaj formula CaCN2. Qhov sib txawv tseem ceeb ntawm calcium cyanide thiab calcium cyanamide yog calcium cyanide yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium cyanamide nrog carbon nyob rau hauv ib tug fused ntsev yaj, whereas calcium cyanamide yog tsim los ntawm nitrogenation ntawm calcium carbide.
