Ụzọ mmepụta ihe n'ụlọ ọrụ mmepụta ihe gụnyere usoro neutralization disodium hydrogen phosphate na usoro neutralization soda ash.
1. Disodium hydrogen phosphate na mmiri neutralization nke disodium hydrogen phosphate iri na abụọ site na oke nke 3:2 tinye mmiri ka ọ gbazee, tee ya iji wepụ ma tinye filtrate na neutralizer na neutralization mmeghachi omume na ngwakọta phosphate nwayọ, njikwa pH na 4.2 ~ 4.6, ngwọta mmeghachi omume site na ịfụ mmiri iji mepụta ihe nkiri kristal, crystallization oyi, nkewa centrifugal, sodium dihydrogen phosphate mmiri abụọ. Mgbe ọ kpọchara na 100℃, a kwadebere sodium dihydrogen phosphate anhydrous. Enwere ike weghachite ihe ọṅụṅụ nne maka ịgbaze disodium hydrogen phosphate.
2. Usoro nkesa ntụ soda: a na-agbakwunye asịd phosphoric ewepụtara n'ime ihe na-eme ka ọ dị ọcha, a na-etinyekwa mmiri soda ntụ nwayọ nwayọ n'ime mmeghachi omume nkesa ka ọ na-akpali iji mepụta sodium dihydrogen phosphate, nke a na-asacha, na-ekupụ ma na-etinye uche, jụọ oyi ruo 60 ~ 70℃ iji mee ka kristal dị ọhụrụ, ma kewaa ya site na centrifugation iji nweta sodium dihydrogen phosphate dihydrate. A na-eji ikuku akpọnwụ sodium dihydrogen phosphate nke na-anaghị amịpụta mmiri.
