aminoguanidinium sulphat
Igama lemveliso: aminoguanidinium sulphat
Ifomula yeMolekyuli:C2H14N8SO4
CAS: Ngo-966-19-0
Indawo yokunyibilika:Iidigri ezingama-206
Ifomula yolwakhiwo:
Sebenzisa:amayeza, ishishini leemoto, iziqhushumbisi
indlela yokwenziwa:
(1) Ifunyanwa ngokusebenza kwe-hydrazine sulphate kunye ne-lime nitrogen kunye ne-neutralization nge-sulfuric acid ukwenza ityuwa: okokuqala, ukumisa i-hydrazine sulphate emanzini, ngokuthe ngcembe yongeza i-nitrogen yekalika phantsi kokupholisa kunye nokuphazamiseka, lawula ubushushu malunga ne-20 ℃, phendula I-8h, emva koko ucofe, uhlambe ikhekhe lokucoca ngamanzi, ukhuphe amanzi; Hlanganisa isisombululo kunye nesisombululo sokuhlamba, ungadibanisi ne-50% ye-asidi ye-sulfuric kwiqondo lobushushu egumbini ukuya kwi-pH = 5, ucofe kwaye ususe i-calcium sulphate, kwaye ujolise kumama ngotywala ngokudodobala Emva kokupholisa, amakristali amhlophe ayanyibilika, ahlanjwa ngamanzi omkhenkce kwaye omile, isivuno simalunga nama-72%. (2) Ukusuka kwimpendulo ye-methyl isothiourea sulphate kunye ne-hydrazine hydrate, i-119ml ye-42% isisombululo se-hydrazine hydrate sachithwa ngevoluyamu elilinganayo lamanzi, emva koko yongezwa kwi-139g ye-methyl isothiourea sulfate kwi-200ml isisombululo samanzi kubushushu be-10 ℃. Imethyl mercaptan ekhutshwe kukusabela ifunxwe kwisisombululo sehydroxide. Emva kokuba isisombululo siphendule kwi-200ml, i-95% ye-ethanol yomthamo ofanayo yongezwa, oko kukuthi, i-aminoguanidine sulphate iyahlulwa ngaphandle, kwaye icrystallization icociwe. Umama wotywala unokuthi ungqiniswe ngokukodwa. Ukucoca i-crystal ngaphakathi

Amanyathelo okhuseleko: Gcina kwindawo yokugcina izinto epholileyo kunye nomoya. Iqondo lobushushu lokugcina akufuneki lidlule kwi-37 ° C. Kufuneka igcinwe ngokwahlukeneyo kwiikhemikhali ezinobungozi kunye nezityiwayo, kwaye ukugcinwa okuxubeneyo akuvumelekanga. Gcina isikhongozeli sitywinwe. Gcina kude nomlilo kunye nobushushu. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zokukhusela umbane. Inkqubo yokukhupha umoya iya kuxhotyiswa ngesixhobo sokususa umbane ongashukumiyo. Yamkela ukukhanya kweziqhushumbisi kunye nokucwangciswa komoya. Akuvumelekile ukusebenzisa izixhobo kunye nezixhobo ezithandwa yintlantsi. Indawo yokugcina iya kuthi ixhotyiswe ngesixhobo sokuvuza esingxamisekileyo kunye nezinto ezifanelekileyo zokufumana
