N-(Isoxazol-5-yl) sulphanilamide tare da CAS 7758-79-4

Hanyoyin samar da masana'antu sun haɗa da hanyar disodium hydrogen phosphate neutralization da hanyar kawar da ash ash.

1. Disodium hydrogen phosphate da neutralization ruwa na disodium hydrogen phosphate na goma sha biyu ta hanyar rabo na 3: 2 ƙara ruwa don narke, tacewa don cirewa da ƙara tacewa zuwa neutralizer da neutralization dauki a cikin phosphate mix sannu a hankali, pH iko a 4.2 ~ 4.6, da dauki. bayani ta hanyar evaporating don samar da fim din crystal, da sanyaya crystallization, centrifugal rabuwa, biyu ruwa sodium dihydrogen phosphate.Bayan bushewa a 100 ℃, an shirya anhydrous sodium dihydrogen phosphate.Za a iya mayar da giya uwar don narkar da disodium hydrogen phosphate.
2. Soda ash neutralization Hanyar: an cire phosphoric acid da aka cire a cikin reactor neutralization, kuma soda ash bayani yana sannu a hankali ƙarawa a cikin maganin neutralization a ƙarƙashin motsawa don samar da sodium dihydrogen phosphate, wanda aka tace, evaporated da mayar da hankali, sanyaya zuwa 60 ~ 70 ℃ zuwa hazo crystallization, kuma rabu da centrifugation don samun sodium dihydrogen phosphate dihydrate.An shirya sodium dihydrogen phosphate anhydrous ta bushewar iska.
