aminoguanidinium sulphat
Igama lomkhiqizo: aminoguanidinium sulphat
Ifomula Yamamolekhula:C2H14N8SO4
I-CAS: 966-19-0
Indawo Yokuncibilika:206 degrees
Ifomula Yesakhiwo:
Sebenzisa:ekhiqiza imithi, imboni yezimoto, iziqhumane
indlela yokwenza:
(1) Itholakala ngesenzo se-hydrazine sulfate ne-lime nitrogen kanye ne-neutralization nge-sulfuric acid ukwakha usawoti: okokuqala, misa i-hydrazine sulfate emanzini, kancane kancane ungeze i-lime nitrogen ngaphansi kokupholisa nokuyaluza, lawula izinga lokushisa cishe ku-20 ℃, phendula nge-8h, bese uhlunga, ugeze ikhekhe lokuhlunga ngamanzi, bese ukhipha; hlanganisa isixazululo se-filtrate nokuwasha, unciphise nge-50% sulfuric acid ekamelweni lokushisa ukuze ube ne-pH = 5, hlunga bese ususa i-calcium sulfate, bese ugxila otshwala bukamama ngokuqeda amandla ngemuva kokupholisa, amakristalu amhlophe ancipha, agezwe ngamanzi e-ice futhi omiswe, isivuno cishe singama-72%. (2) Ukusuka ekuphenduleni kwe-methyl isothiourea sulfate ne-hydrazine hydrate, i-119ml 42% isixazululo se-hydrazine hydrate sahlanjululwa ngomthamo olinganayo wamanzi, sabe sesingezwa ku-139g we-methyl isothiourea sulfate ku-200ml solution enamanzi okushisa ayi-10 ℃. Imethyl mercaptan ekhishwe ekuphenduleni ifakwa kwisisombululo se-sodium hydroxide. Ngemuva kokuthi isisombululo sokuphendula sigxilwe ku-200ml, i-95% ethanol yevolumu efanayo ingeziwe, okungukuthi, i-aminoguanidine sulfate ihlukanisiwe, futhi i-crystallization iyahlungwa. Utshwala obungumama bungakhanyiselwa kancane. Ukomisa ikristalu ngaphakathi

Izinyathelo zokuqapha isitoreji: gcina endaweni yokugcina impahla epholile futhi enomoya. Izinga lokushisa lokugcina akufanele leqe ama-37 ° C. Kufanele ligcinwe ngokuhlukile kumakhemikhali e-oxidant nadliwayo, futhi isitoreji esihlanganisiwe sinqatshelwe. Gcina isitsha esivaliwe. Hlala kude nomlilo nokushisa. Indawo yokugcina impahla kumele ifakwe izinto zokuvikela umbani. Isistimu yokukhipha umoya izofakelwa isisetshenziswa sokususa ugesi omile. Yamukela ukukhanyisa okukhombisa ukuqhuma nezilungiselelo zomoya. Akuvunyelwe ukusebenzisa imishini namathuluzi we-spark. Indawo yokugcina izofakelwa imishini yokwelashwa okuphuthumayo kanye nezinto zokwamukela ezifanele
