Cov Qauv Qauv:
Kev siv:kev lag luam kws kho tsheb, kev lag luam tsheb, tshuaj tawg
hluavtaws qauv:
(1) Nws tau los ntawm kev ua ntawm hydrazine sulfate thiab txiv qaub nitrogen thiab neutralization nrog sulfuric acid los ua ntsev: ua ntej, muab hydrazine sulfate tso rau hauv dej, maj mam ntxiv cov kua qaub nitrogen nyob rau hauv qhov txias thiab ntxhov siab, tswj qhov kub ntawm li 20 ℃, hnov mob rau 8h, tom qab ntawd lim, ntxuav cov lim ncuav mog qab zib nrog dej, thiab ntws; sib xyaw ua ke ntawm cov lim dej thiab ntxuav cov tshuaj, nruab nrab nrog 50% sulfuric acid nyob rau hauv chav tsev kom pH = 5, lim thiab tshem tawm cov calcium sulfate, thiab mloog zoo rau tus niam cawv los ntawm decompression Tom qab txias, cov muaju dawb yog nag lossis daus, ntxuav nrog dej khov thiab kom qhuav, cov yield yog li 72%. (2) Los ntawm cov tshuaj tiv thaiv ntawm methyl isothiourea sulfate thiab hydrazine hydrate, 119ml 42% hydrazine hydrate tov tau diluted nrog cov dej sib npaug, thiab tom qab ntawd nws tau ntxiv rau 139g ntawm methyl isothiourea sulfate hauv 200ml aqueous tov ntawm qhov kub ntawm 10 ℃. Cov methyl mercaptan tso tawm los ntawm cov tshuaj tiv thaiv yog nqus mus rau hauv cov tshuaj sodium hydroxide. Tom qab cov tshuaj tiv thaiv tau suav daws mus rau 200ml, 95% ethanol ntawm tib lub ntim yog ntxiv, uas yog, aminoguanidine sulfate yog cais tawm, thiab crystallization yog lim tawm. Cov cawv txiv hmab kuj tuaj yeem nrog qee khoob. Kom qhuav lub crystal hauv

Qhov yuav tau ceev faj: muab cia rau qhov chaw zoo thiab muaj cua. Qhov chaw cia khoom txias yuav tsum tsis txhob ntau dua 37 ° C. Nws yuav tsum khaws cia cais tawm ntawm cov tshuaj tua kab mob oxidant thiab cov tshuaj, thiab cov khoom sib xyaw txwv tsis pub. Kaw lub thauv. Txav deb ntawm hluav taws thiab kub. Lub chaw rau khoom yuav tsum muaj cov cuab yeej tiv thaiv xob laim. Lub tshuab pa pa hluav taws xob yuav tsum tau nruab nrog cov cuab yeej av hauv av kom tshem tawm hluav taws xob zoo li qub. Txais yuav tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa. Nws yog txwv tsis pub siv cov khoom hnyav thiab cov cuab yeej. Thaj chaw khaws cia yuav tsum muaj cov cuab yeej siv kho mob lub sij hawm tiv thaiv kev kub ntxhov thiab cov khoom txais uas tsim nyog
