Tannic acid ndiyo yakatarwa tannin, rudzi rwepolyphenol. Iyo isina kusimba acidity (pKa yakatenderedza 6) inokonzerwa nemapoka akawanda e phenol mune chimiro. Iyo kemikari fomula yekutengesa tannic acid inowanzo kupihwa seC76H52O46, inoenderana ne decagalloyl glucose, asi pachokwadi iri musanganiswa we polygalloyl glucoses kana polygalloyl quinic acid esters ine huwandu hwegalloyl moitions pa molecule inotangira kubva pa2 kusvika pa12 zvichienderana nesosi yemuti inoshandiswa kubvisa iyo tannic acid. Commerce tannic acid inowanzo kubviswa kubva kune chero anotevera zvikamu zvemiti: Tara pods (Caesalpinia spinosa), nduru dzinobva kuRhus semialata kana Quercus infectoria kana Sicilian sumac mashizha

iconZvishandiso

1. Ichi chigadzirwa chinoshandiswa zvakanyanya mukugadzira uye acid acid inki yekugadzira.

2. Inoshandiswa kugadzira ganda rekusvinira mumiriri, mordant, rubber coagulant, protein mumiriri, alkaloid precipitant.

3. Zvigadzirwa zvemishonga, senge mbishi zvigadzirwa zve sulfa synergists (TMP).

4. Raw zvinhu zvekugadzirira mishonga asidhi, pyrogallic acid uye sulfa zvinodhaka zvakare mbishi zvinhu zvekugadzira gallic acid uye pyrogallol.

5. Iko kushandiswa kwesimbi yakagadzirwa nematanini yakaferefetwa kubvisa mercury uye methylmercury kubva pamhinduro. Matani asina simba akaedzwa kuti awane uraniani kubva mumvura yegungwa.

6. Tannins inogona kushandiswa mukugadzira anti-corrosive primer.
