N-(Isoxazol-5-yl)sulphanilamide fa'atasi ai ma le CAS 7758-79-4
O auala gaosi oloa fa'apisinisi e aofia ai le metotia o le fa'ate'aina o le disodium hydrogen phosphate ma le metotia o le fa'ate'aina o le soda ash.
1. Fa'aopoopo le vai e fa'amamā ai le disodium hydrogen phosphate ma le vai fa'amamāina o le disodium hydrogen phosphate e sefululua i le fua fa'atatau o le 3:2, fa'amamā e aveese ma fa'aopoopo le filtrate i le neutralizer ma fa'agasolo malie le tali atu i le phosphate, pulea le pH i le 4.2 ~ 4.6, fa'agasolo le tali atu e ala i le fa'apuna e fausia ai se ata tioata, fa'amālūlūina le crystallization, vaeluaina i le centrifugal, ma fa'amamāina le sodium dihydrogen phosphate i le vai e lua. A mae'a ona fa'amago i le 100 ℃, ona saunia lea o le sodium dihydrogen phosphate anhydrous. E mafai ona toe fa'afo'i le vai tina e fa'amamā ai le disodium hydrogen phosphate.
2. Metotia e fa'aitiitia ai le lefulefu o le soda: e fa'aopoopoina le phosphoric acid ua fa'a'esea i totonu o le neutralization reactor, ona fa'aopoopo malie lea o le soda ash solution i totonu o le neutralization reaction i lalo o le fa'agae'etia e maua ai le sodium dihydrogen phosphate, lea e fa'amamāina, fa'a'asu ma fa'aputu, fa'amālūlūina i le 60 ~ 70 ℃ e fa'atupu ai le crystallization, ma vavae'ese e ala i le centrifugation e maua ai le sodium dihydrogen phosphate dihydrate. Sa saunia le sodium dihydrogen phosphate e aunoa ma le vai e ala i le fa'amago i le ea.
