ʻAkika Tannic

Hōʻike Pōkole:

Inoa mea kūʻai: ʻAkika waikiki

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

Nā inoa ʻē aʻe: ʻO Acidum tannicum, ʻo Gallotannic acid, Digallic acid, Gallotannin, Tannimum, Quercitannin, ʻoi bark tannin, Quercotannic acid, Querci-tannic acid, Querco-tannic acid

Inoa mea kūʻai: ʻAkika waikiki

ʻO ke Tannic acid kahi ʻano kikoʻī o ka tannin, kahi ʻano polyphenol. ʻO kona acidity nāwaliwali (pKa ma kahi o 6) ma muli o nā hui phenol lehulehu i ka hanana. Hāʻawi pinepine ʻia ke kumumea kemika no ka acid tannic acid e like me C76H52O46, i kūlike me ka decagalloyl glucose, akā i ka ʻoiaʻiʻo he hui ʻana o polygalloyl glucoses a i ʻole polygalloyl quinic acid esters me ka helu o nā moieties galloyl ma kēlā mole mai 2 a hiki i 12 ma muli o ke kumuwaiwai i hoʻohana ʻia e unuhi i ka waikiki tannic. Lawe mau ʻia ka tannic acid mai kekahi o nā mea kanu e like me kēia: Tara pods (Caesalpinia spinosa), mau lāʻau ʻalalā mai Rhus semialata a i ʻole Quercus infectoria a i ʻole Sisilian sumac lau

iconHoʻohana

1. Hoʻohana ākea kēia huahana i ka unuhi a me ka hana ʻana i ka inika hao.

2. Hoʻohana ʻia e hana i ka ʻili humuhumu ʻili, mordant, coagulant rubber, agent protein, alkaloid precipitant.

3. Nā huahana lāʻau lapaʻau, e like me nā mea maka no nā sulfa synergists (TMP).

4. ʻO nā mea makaukau no ka hoʻomākaukau ʻana i ka waikawa lāʻau, pyrogallic acid a me nā lāʻau sulfa kekahi mea maka no ka hana ʻana i ka waikawa gallic a me pyrogallol.

5. Ua nānā ʻia ka hoʻohana ʻana o nā kēpau i hana ʻia i nā taninini e kāpae aku i ka mercury a me ka methylmercury mai ka hopena. Ua hoʻāʻo ʻia nā tannin Immobilized e hoʻōla i ka uranium mai ke kai kai.

6. Hiki ke hoʻohana i nā tanin no ka hana anti-corrosive primer.
