Daim ntawv thov

Potassium hydrogen phthalate feem ntau yog siv rau kev ntsuas ntawm sodium hydroxide tus qauv kev daws teeb meem vim nws yooj yim kom tau txais cov khoom ntshiab los ntawm recrystallization, tsis muaj dej crystallization, tsis yog hygroscopicity, yooj yim cia, thiab siab sib npaug; Nws tseem tuaj yeem siv rau kev ntsuas cov tshuaj acetic acid nrog perchloric acid (siv methyl violet ua qhov ntsuas).
