Maselo Chilinganizo:C2H14N8SO4
CAS: 966-19-0
Limatsogolera mfundo:Madigiri 206
Kandalama chilinganizo:
Gwiritsani ntchito:mankhwala, makampani magalimoto, zachiwawa
njira yopangira:
(1) Amapezeka ndi machitidwe a hydrazine sulphate ndi laimu nayitrogeni ndi kutsekemera ndi sulfuric acid kuti apange mchere: choyamba, kuyimitsa hydrazine sulphate m'madzi, pang'onopang'ono kuwonjezera laimu nayitrogeni pansi pa kuziziritsa ndi kusakhazikika, kuwongolera kutentha pafupifupi 20 ℃, kuchitapo kanthu kwa 8h, kenako muzisefa, kutsuka kekeyo ndi madzi, ndikukhetsa; phatikizani fyuluta ndi yankho, osungunuka ndi 50% ya asidi sulfuric kutentha kutentha kwa pH = 5, fyuluta ndikuchotsa calcium sulphate, ndikuyikapo zakumwa za amayi mwa kupsinjika Pambuyo pozizira, makhiristo oyera amaphulika, kutsukidwa ndi madzi oundana ndikuuma, zokolola zili pafupifupi 72%. (2) Kuchokera pazomwe methyl isothiourea sulphate ndi hydrazine hydrate, 119ml 42% yankho la hydrazine hydrate idasungunuka ndimadzi ofanana, kenako idawonjezeredwa ku 139g ya methyl isothiourea sulphate mu 200ml yothetsera madzi otentha 10 ℃. Methyl mercaptan yomwe imatulutsidwa munthawiyi imalowa mu sodium hydroxide solution. Pambuyo poyankha yankho ladzaza mpaka 200ml, 95% ethanol ya voliyumu yomweyo imawonjezedwa, ndiyo, aminoguanidine sulphate imagawanika, ndipo crystallization imasefedwa. Mowa wamayi amathanso kuphatikizidwa pang'ono. Kuyanika kristalo mkati

Zisamaliro zosungira: sungani mosungira kozizira komanso kozizira. Kutentha kosungira sikuyenera kupitirira 37 ° C. Iyenera kusungidwa mosiyana ndi mankhwala amadzimadzi ndi odyetsedwa, ndipo zosakaniza zosakanizidwa ndizoletsedwa. Sungani chidebe chosindikizidwa. Khalani kutali ndi moto ndi kutentha. Nyumba yosungiramo katundu iyenera kukhala ndi zida zoteteza mphezi. Makina otulutsa mpweya azikhala ndi chida chokhazikitsira magetsi kuti azichotsa magetsi. Landirani kuyatsa kosonyeza kuphulika ndi mawonekedwe ampweya. Ndizoletsedwa kugwiritsa ntchito zida ndi zida zoyambira. Malo osungira azikhala ndi zida zochiritsira zodontha mwadzidzidzi ndi zida zoyenera kulandira
