N-(Isoxazol-5-yl)sulphanilamide nrog CAS 7758-79-4
Cov txheej txheem tsim khoom lag luam suav nrog disodium hydrogen phosphate neutralization txoj kev thiab soda ash neutralization txoj kev.
1. Disodium hydrogen phosphate thiab dej neutralization 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 tshuaj tiv thaiv hauv phosphate sib tov qeeb qeeb, pH tswj hauv 4.2 ~ 4.6, cov tshuaj tiv thaiv los ntawm evaporating los ua cov zaj duab xis siv lead ua, txias crystallization, centrifugal sib cais, ob dej sodium dihydrogen phosphate. Tom qab ziab ntawm 100 ℃, anhydrous sodium dihydrogen phosphate tau npaj. Cov dej cawv niam tuaj yeem rov qab los rau disodium hydrogen phosphate yaj.
2. Txoj kev ua kom cov tshauv tsis muaj zog: cov kua phosphoric acid uas tau rho tawm lawm raug ntxiv rau hauv lub tshuab ua kom tsis muaj zog, thiab cov kua tshauv tsis muaj zog maj mam ntxiv rau hauv qhov kev ua kom tsis muaj zog hauv qab kev sib xyaw kom tsim cov sodium dihydrogen phosphate, uas tau lim, ua kom qhuav thiab ua kom muaj zog, txias rau 60 ~ 70 ℃ kom ua rau cov crystallization sai, thiab sib cais los ntawm centrifugation kom tau txais sodium dihydrogen phosphate dihydrate. Anhydrous sodium dihydrogen phosphate tau npaj los ntawm kev ziab cua.
