Lub cev thiab tshuaj muaj zog
Sodium dihydrogen phosphate tuaj yeem muab faib ua anhydrous thiab dihydrate. Cov dihydrate tsis muaj xim rau dawb, crystalline, los yog crystalline hmoov, thiab cov tshuaj anhydrous yog cov hmoov dawb los yog particle. Soluble hauv dej (25 degree, 12.14 feem pua), yuav luag insoluble hauv ethanol. Cov tshuaj aqueous yog acidic, thiab pH tus nqi ntawm 1 feem pua cov tshuaj yog hais txog 4.1-4.7. Thaum cov dej siv lead ua poob ntawm 100 degree, cov kua qaub sodium pyrophosphate yuav tsim.
Concentrated phosphoric acid yog ntxiv nrog sodium hydroxide los yog sodium carbonate, concentrated nyob rau hauv kev tswj ntawm pH 4.4-4.6, thiab crystallized ntawm 41 degree C los npaj sodium dihydrogen phosphate uas muaj ob molecules dej.

Condensed mis nyuj yuav muaj thermal coagulation thiab lwm yam tsis xws luag thaum cua sov thiab sterilization. Yog vim li cas cuam tshuam rau thermal stability ntawm condensed mis nyuj feem ntau yog tias muaj ntau cov calcium ions dawb thiab tsawg phosphoric acid thiab citric acid. Txhawm rau kom cov ntsev sib npaug, txhim kho nws cov thermal stability thiab tiv thaiv cov khoom los ntawm thermal solidification, phosphate thiab citrate tuaj yeem muab ntxiv ua stabilizers. Tus nqi ntawm stabilizer ntxiv yog feem ntau txiav txim siab raws li kev kho cua sov ntawm cov qauv me me. Qhov kev siv tiag tiag yog 0.2-0.3g/kg.
