Nā Kūlana Kūlana:
Hoʻohana:lāʻau lapaʻau, ʻoihana kaʻa, pahū
hana synthetic:
(1) Loaʻa iā ia e ka hana o ka hydrazine sulfate a me ka lime nitrogen a me ka neenee ʻana me ka waikawa sulfuric e hana i ka paʻakai: ʻo ka mea mua, e kāpae i ka Hydrazine sulfate i ka wai, e hoʻonui mālie i ka nitrogen lime ma lalo o ke anuanu a me ka hoʻonāukiuki, kaohi i ka mahana ma kahi o 20 ℃, hana no 8h, a laila kānana, holoi i ka palaoa kānana me ka wai, a hoʻokahe; hoʻohui i ka kānana kānana a me ka holoi, hoʻopau me 50% waikawa sulfuric i ka mahana wela i ka lumi = =, kānana a hemo i ka calcium sulfate, a noʻonoʻo i ka waiʻona makuahine ma o ka decompression Ma hope o ke anuanu, hoʻāla ʻia nā aniani keʻokeʻo, holoi ʻia me ka wai hau a maloʻo, ka ʻo ka hua ma kahi o 72%. (2) Mai ka hopena o ka methyl isothiourea sulfate a me ka hydrrazine hydrate, ua hoʻoheheʻe ʻia ʻo 119ml 42% Hydrazine hydrate solution me ka nui o ka wai, a laila ua hoʻohui ʻia i 139g o ka methyl isothiourea sulfate i ka hopena wai 200ml ma kahi mahana o 10 ℃. Hoʻokomo ʻia ka methyl mercaptan mai ka hopena i loko o ka hopena sodium hydroxide. Ma hope o ka hopena o ka hopena i 200ml, 95% ethanol o ka leo like i hoʻohui ʻia, ʻo ia hoʻi, ua hoʻokaʻawale ʻia ʻo aminoguanidine sulfate, a kānana ʻia ka crystallization. Hiki ke crystallized kekahi hapa i ka rama o ka makuahine. Ke hoʻomaloʻo nei i ke aniani i loko
