N- (Isoxazol-5-yl) sulfanilamide nrog CAS 7758-79-4
Cov txheej txheem tsim muaj xws li disodium hydrogen phosphate neutralization txoj kev thiab dej qab zib tshauv neutralization txoj kev.
1. Disodium hydrogen phosphate thiab neutralization dej ntawm kaum ob disodium hydrogen phosphate los ntawm qhov sib piv ntawm 3: 2 ntxiv dej kom yaj, lim kom tshem tawm thiab ntxiv filtrate rau neutralizer thiab neutralization cov tshuaj tiv thaiv hauv phosphate mix maj mam, pH tswj hauv 4.2 ~ 4.6, cov tshuaj tiv thaiv. Kev daws los ntawm evaporating rau daim ntawv siv lead ua zaj duab xis, qhov txias crystallization, centrifugal sib cais, ob dej sodium dihydrogen phosphate. Tom qab ziab ntawm 100 ℃, anhydrous sodium dihydrogen phosphate tau npaj. Niam cawv tuaj yeem xa rov qab rau disodium hydrogen phosphate dissolving.
2. Soda tshauv neutralization txoj kev: cov extracted phosphoric acid yog ntxiv rau hauv neutralization reactor, thiab cov dej qab zib tshauv yog maj mam ntxiv rau hauv cov tshuaj tiv thaiv neutralization nyob rau hauv stirring los tsim sodium dihydrogen phosphate, uas yog lim, evaporated thiab concentrated, txias rau 60 ~ 70 ℃ rau precipitate crystallization, thiab sib cais los ntawm centrifugation kom tau sodium dihydrogen phosphate dihydrate. Anhydrous sodium dihydrogen phosphate tau npaj los ntawm huab cua kom qhuav.
