aminoguanidinium sulphat
Chigadzirwa Chigadzirwa: aminoguanidinium sulphat
Molecular Formula:C2H14N8SO4
CAS: 966-19-0
Kunyorera Point:206 madhigirii
Structural Formula:
Shandisa:mishonga, indasitiri yemotokari, zvinoputika
nzira yekugadzira:
(1) Inowanikwa nekuita kwehydrazine sulphate uye lime nitrogen uye kusagadzikana nesulfuric acid kugadzira munyu: kutanga, misa hydrazine sulphate mumvura, zvishoma nezvishoma wedzera lime nitrogen pasi pekunonoka nekushushikana, kudzora tembiricha ingangoita 20 ℃, ita kwe8h, wozosefa, geza iro keke remvura nemvura, uye dhonza; sanganisa iyo filtrate uye yekuwacha mhinduro, sanganisa ne50% sulfuric acid pakamuri yekupisa kusvika pH = 5, sefa uye ubvise calcium sulfate, woisa amai doro kuburikidza nekudzvinyirira Mushure mekutonhora, machena machena anoputirwa, akashambidzwa nemvura yechando uye akaomeswa, iyo goho riri pamusoro pe72%. (2) Kubva pakuita kwemethyl isothiourea sulfate uye hydrazine hydrate, 119ml 42% hydrazine hydrate solution yakasanganiswa neyakaenzana mvura, uye ndokuzowedzerwa ku139g yemethyl isothiourea sulfate mu200ml aqueous solution patembiricha ye10 ℃. Iyo methyl mercaptan yakaburitswa kubva kune inoitika inopinzwa mune iyo sodium hydroxide mhinduro. Mushure memhinduro yekugadzirisa yakaiswa kune 200ml, 95% ethanol yeiyo vhoriyamu yakawedzerwa, kureva kuti, aminoguanidine sulphate yakakamurwa kunze, uye crystallization inosvinwa kunze. Ivo amai doro vanogonawo kuve vakaomeswa zvishoma. Kuomesa iyo crystal mukati

Kuchengetedza kwekuchengetedza: chitoro mune inotonhorera uye ine mweya yekuchengetera. Iyo tembiricha yekuchengetera haifanire kupfuura 37 ° C. Inofanirwa kuchengetwa yakaparadzaniswa nemakemikari anodyiwa uye anodyiwa, uye kuchengetedza kwakasanganiswa kunorambidzwa. Chengeta mudziyo wakavharwa. Gara kure nemoto uye kupisa. Imba yekuchengetera inofanirwa kuve nemidziyo yekudzivirira mheni. Iyo yemhepo chiutsi sisitimu ichave yakagadzirirwa zvigadzirwa zvevhu rekubvisa static magetsi. Tora kuputika-chiratidzo chemwenje uye marongero emhepo. Zvinorambidzwa kushandisa michina isingatani kupenya uye zvishandiso. Iyo nzvimbo yekuchengetera ichave yakagadzirirwa neakavu yekurumidzira ekurapa michina uye yakakodzera yekugamuchira zvinhu
