Qaaciddada qaabdhismeedka:
Isticmaal:dawooyinka, warshadaha baabuurta, waxyaabaha qarxa
habka synthetic:
(1) Waxaa lagu helaa ficilka hydrazine sulfate iyo lime nitrogen iyo dhexdhexaadinta leh sulfuric acid si loo sameeyo cusbo: marka hore, hakin hydrazine sulfate biyo, si tartiib tartiib ah ugu dar nitrogen liin hoosta qaboojinta iyo kacdoonka, xakamey heerkulka qiyaastii 20 ℃, falcelin 8h, ka dib shaandhee, ku maydh keega miiraha biyo, oo ka daadi; isku dar xalka filtrate-ka iyo dhaqida, kala saar 50% sulfuric acid heerkulka qolka illaa pH = 5, shaandhee oo ka saar kalsiyum sulfate, iskuna ururi qamriga hooyada adoo adeegsanaya kala-daadasho Ka dib qaboojinta, kiristaalo cad ayaa la soo rogay, waxaa lagu dhaqay biyo baraf ah waana la qalajiyey waxsoosaarka waa qiyaastii 72%. (2) Dareenka methyl isothiourea sulfate iyo hydrazine hydrate, 119ml 42% hydrazine hydrate solution ayaa lagu qasiyey cabir biyo ah oo le'eg, ka dibna waxaa lagu daray 139g oo ah methyl isothiourea sulfate oo ku jirta 200ml xalka aqueous heerkulka 10 ℃. Methyl mercaptan oo laga sii daayay falcelinta ayaa lagu dhex shubay xalka sodium hydroxide. Ka dib marka xalka falcelinta la isugu geeyo 200ml, 95% ethanol oo isku mug ah ayaa lagu daraa, kuwaas oo kala ah, aminoguanidine sulfate waa lakala saaray, oo crystallization ayaa la sifeeyaa. Khamriga hooyadu sidoo kale qayb ahaan waa la qaybin karaa. Qalajinta muraayadda gudaha

Taxaddarrada keydinta: ku kaydso bakhaar qabow oo hawo leh. Heerkulka keydinta waa inuusan ka badnaan 37 ° C. Waa in lagu kaydiyaa si ka duwan oksaydhyada iyo kiimikooyinka la cuni karo, kaydinta isku dhafanna waa mamnuuc. Weelka ha la xidho. Ka fogow dabka iyo kuleylka. Bakhaarka waa inuu lahaadaa qalab ilaaliya hillaaca. Nidaamka qiiqa hawada waa inuu ku qalabeeyaa aaladda dhulka lagu rakibo si looga saaro korontada taagan. Qaado nalalka astaamaha qarxa iyo hawo-qaadashada. Waa mamnuuc in la isticmaalo qalabka dhimbiilaha iyo qalabka. Aagga keydinta waa in lagu qalabeeyaa qalabka daaweynta xaaladaha degdegga ah ee daadinta iyo alaabada ku habboon ee la qaato
