Iithegi zeMveliso

Igama lemveliso:Tannic acid

I-acid ye-tannic luhlobo oluthile lwe-tannin, uhlobo lwe-polyphenol.Ubuthathaka bayo be-asidi (pKa malunga ne-6) kungenxa yamaqela amaninzi e-phenol kwisakhiwo.Ifomula yeekhemikhali ye-asidi ye-tannic yorhwebo idla ngokunikwa njenge-C76H52O46, ehambelana ne-glucose ye-decagalloyl, kodwa eneneni ngumxube we-polygalloyl glucoses okanye i-polygalloyl quinic acid esters kunye nenani le-galloyl moieties nge-molecule ukusuka kwi-2 ukuya kwi-12 kuxhomekeke kumthombo wesityalo esisetyenziselwa ukukhupha i-tannic acid.I-asidi ye-tannic yorhwebo idla ngokutsalwa nakweyiphi na kula malungu esityalo alandelayo: iTara pods (Caesalpinia spinosa), igallnuts esuka kwiRhus semialata okanye iQuercus infectoria okanye amagqabi eSicilian sumac.

iconUsebenzisa

1. Le mveliso isetyenziswa ngokubanzi kwi-extraction kunye ne-acid iron inki yokuvelisa.

2. Isetyenziselwa ukuvelisa i-agent yesikhumba, i-mordant, i-rubber coagulant, i-protein agent, i-alkaloid precipitant.

3. Iimveliso zamachiza, ezifana nezixhobo ze-sulfa synergists (TMP).

4. Imathiriyeli ekrwada yokulungiselela i-asidi yamayeza, i-pyrogallic acid kunye ne-sulfa iziyobisi nazo zinezinto eziluhlaza zokuvelisa i-gallic acid kunye ne-pyrogallol.

5. Ukusetyenziswa kwee-resin ezenziwe nge-tannins kuphandwe ukususa i-mercury kunye ne-methylmercury kwisisombululo.Iitannins ezingashukumiyo ziye zavavanywa ukufumana iuranium emanzini olwandle.

6. I-Tannins ingasetyenziselwa ukuveliswa kwe-primer anti-corrosive primer.
