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

Hanyoyin samar da kayayyaki na masana'antu sun haɗa da hanyar rage sinadarin hydrogen phosphate na disodium da kuma hanyar rage sinadarin soda ash.

1. Disodium hydrogen phosphate da ruwan disodium hydrogen phosphate mai disodium goma sha biyu bisa ga rabon 3:2, ƙara ruwa don narkewa, tacewa don cirewa sannan a ƙara tacewa zuwa mai hana ruwa da kuma maganin hana ruwa a cikin cakuda phosphate a hankali, sarrafa pH a cikin 4.2 ~ 4.6, maganin hana ruwa ta hanyar fitar da iska zuwa fim ɗin kristal, sanyaya crystallization, rabuwar centrifugal, sodium dihydrogen phosphate na ruwa guda biyu. Bayan bushewa a 100℃, an shirya sodium dihydrogen phosphate mai hana ruwa. Ana iya mayar da ruwan giyar don narke disodium hydrogen phosphate.
2. Hanyar rage sinadarin ash na Soda: ana ƙara sinadarin phosphoric da aka cire a cikin na'urar rage sinadarin ash, sannan a ƙara ruwan ash na soda a hankali a cikin amsawar rage sinadarin a lokacin da ake juyawa don samar da sinadarin sodium dihydrogen phosphate, wanda ake tacewa, a fitar da shi sannan a tattara shi, a sanyaya shi zuwa digiri 60 ~ 70 don ya haifar da crystallization, sannan a raba shi da centrifugation don samun sinadarin sodium dihydrogen phosphate dihydrate. An shirya sinadarin sodium dihydrogen phosphate wanda ba shi da ruwa ta hanyar busar da shi ta iska.
