Amanye amagama: I-Acidum tannicum, i-Gallotannic acid, i-Digallic acid, i-Gallotannin, i-Tannimum, i-Quercitannin, i-Oak bark tannin, i-Quercotannic acid, i-Querci-tannic acid, i-Querco-tannic acid


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Igama lomkhiqizo: I-Tannic acid

I-Tannic acid iyindlela ethile ye-tannin, uhlobo lwe-polyphenol. I-asidi yayo ebuthakathaka (pKa cishe 6) kungenxa yamaqembu amaningi e-phenol esakhiweni. Ifomula yamakhemikhali ye-tannic acid yokuhweba ivame ukunikezwa njenge-C76H52O46, ehambelana ne-decagalloyl glucose, kepha empeleni iyinhlanganisela yama-polygalloyl glucoses noma i-polygalloyl quinic acid esters enenombolo yama-galloyl moitions nge-molecule ngayinye esukela ku-2 kuye ku-12 kuya ngomthombo wesitshalo osetshenzisiwe ukukhipha i-tannic acid. I-tannic acid yezohwebo ivame ukukhishwa kunoma yiziphi izingxenye zezitshalo ezilandelayo: Ama-Tara pods (Caesalpinia spinosa), ama-gallnuts avela ku-Rhus semialata noma i-Quercus infectoria noma amaqabunga eSicilian sumac

Igama Chemical: 1,2,3,4,6-penta-O- {3,4-dihydroxy-5 - [(3,4,5-trihydroxybenzoyl) oxy] benzoyl} -D-glucopyranose

Amanye amagama: I-Acidum tannicum, i-Gallotannic acid, i-Digallic acid, i-Gallotannin, i-Tannimum, i-Quercitannin, i-Oak bark tannin, i-Quercotannic acid, i-Querci-tannic acid, i-Querco-tannic acid

Ifomula Yamamolekhula: C76H52O46,

Isisindo Yamamolekhula: 1701.19

Iphuzu lokuncibilika: ibola ngaphezulu kwama-200 °C

Inombolo ye-CAS : 1401-55-4

Inkomba yekhwalithi: Umkhiqizo uhambisana ne-GB5308-85 ejwayelekile kazwelonke.

iconIsebenzisa

1. Lo mkhiqizo usetshenziswa kabanzi ekukhiqizeni nasekukhiqizeni i-asidi yensimbi.

2. Isetshenziselwa ukukhiqiza isikhumba sokushuka isikhumba, i-mordant, i-coagulant yenjoloba, i-protein agent, i-alkaloid precipitant.

3. Imikhiqizo yezemithi, njengezinto zokusetshenziswa zama-sulfa synergists (TMP).

4. Impahla eluhlaza yokulungiselela i-acid yokwelapha, i-pyrogallic acid kanye nemithi ye-sulfa nakho kuyizinto eziluhlaza zokukhiqiza i-gallic acid ne-pyrogallol.

5. Kuphenywe ukusetshenziswa kwezinhlaka ezenziwe ngama-tannins ukuze kususwe isixazululo se-mercury ne-methylmercury. Kuhlolwe ama-tannin angenawo amandla okuthola i-uranium emanzini olwandle.

6. Ama-Tannin angasetshenziselwa ukukhiqizwa kwe-primer anti-corrosive.
