hluavtaws qauv
Nws yog tsim los ntawm cov kua qaub nitrogen, hydrazine hydrate, ammonium bicarbonate lossis sodium bicarbonate. Ntxiv dej distilled rau txiv qaub nitrogen, cia nws nyob ntawm 45-50℃ rau 6h, lim cov roj pov tseg kom tau cov tshuaj cyanamide (calcium), tom qab ntawd ntxiv cov tshuaj sulfuric acid rau cyanamide (calcium) tov rau pH = 6-7, txias nws rau chav sov, lim cov calcium sulfate kom tau cov tshuaj cyanamide, tom qab ntawd ntxiv 5% hydrazine hydrate rau cov kua cyanamide, khaws cia ntawm 50 ℃ rau 4h, tom qab ntawd ntxiv ammonium bicarbonate, tso nws, nag lossis daus thiab lim cov kua, lim nws kom qhuav yuav tsum yog amino acid Guanidine bicarbonate nyoos khoom, ntxiv acetic acid rau yaj cov khoom nyoos, ntxiv oxalic acid, lim cov calcium oxalate, kho cov kua pH = 8 ~ 9 nrog dej ammonia, ntxiv me ntsis disodium EDTA, lim nws kom meej, ntxiv lim dej ammonium bicarbonate tov, qhov chaw, crystallize, lim nws qhuav, ntxuav nws nrog dej distilled thiab ethanol feem, thiab lim nws qhuav kom tau txais qhov ua tiav khoom.
