Ukusetshenziswa
I-gallic acid (GA), eyaziwa nangokuthi i-gallnut acid, iyisakhi sama-tannins angafakwa amanzi futhi inegama lamakhemikhali elithi 3,4, 5-trihydroxybenzoic acid. I-Gallic acid inokuqukethwe okuphezulu kakhulu etiyeni le-Yunnan Pu 'er futhi ngokwayo inemiphumela eminingi yebhayoloji efana nokulwa namagciwane, ukuvuvukala, umdlavuza kanye nokulwa nokuguqulwa kwezakhi zofuzo.
I-Gallic acid isetshenziswa kakhulu kwezokwelapha, kuyinki, odayi, ukudla, embonini yokukhanya kanye nokuhlanganiswa kwezinto eziphilayo, njll. I-Gallic acid isabela nama-ion ensimbi amathathu ukuze yakhe i-precipitate eluhlaza okwesibhakabhaka nomnyama, okuyizinto zokusetshenziswa ze-inki eluhlaza okwesibhakabhaka nomnyama. Iphinde isetshenziswe embonini yokwenza isikhumba. Ingasetshenziswa futhi njengomthuthukisi wezithombe. I-Propyl gallate iyi-antioxidant futhi ingasetshenziswa emafutheni adliwayo nasemafutheni ukuvimbela ukonakala nokuwohloka. Kwezokwelapha, i-gallic acid iyi-ejenti yokwehlisa igazi nokuncibilikisa, kanye nokucasula okuncane kwendawo.
Inemiphumela yokulwa namagciwane futhi ingasetshenziswa ekwelapheni isifo sohudo esibangelwa yi-bacillary. Inemiphumela yokudambisa ukuvuvukala, ukuhlanza igazi kanye nokulwa nohudo. Ingasetshenziswa njengesivikelo. Ingasetshenziswa ukulungiselela i-pyrogallic acid, izidakamizwa, uyinki, amadayi aphakathi kanye nama-anti-explosion agents, njll. Iphinde isetshenziswe njengonjiniyela kanye ne-analytical reagent yokuthola ama-inorganic acids amahhala, i-dihydroxyacetone, ama-alkaloid kanye nezinsimbi, njll.
Ingasetshenziswa njengesivikelo, futhi ingasetshenziswa ukulungiselela udayi ophakathi nendawo kanye nezinto ezilwa nokuqhuma, njll.
Kusetshenziswa njenge-reagent yamakhemikhali
Isetshenziswa kakhulu njengombala we-inki eluhlaza okwesibhakabhaka nomnyama. Isetshenziswa embonini yezemithi ukulungiselela i-sulfonamide potentiator TMP kanye ne-ejenti ehlanganisa ama-sulfonamides njenge-SMZ kanye ne-SD-ethyl. Imboni yokudla iyisebenzisela ukulungiselela i-gallic acid elondolozayo. Isetshenziswa embonini yezokuvikela ukulungiselela ama-ejenti angaqhumi. Ngaphezu kwalokho, ingasetshenziswa nasekukhiqizweni kwamadayi e-mordant kanye nanjengonjiniyela, njll.
Isetshenziswa njenge-depolarizer ekuhlaziyweni kwe-electrochemical; isetshenziselwa ukunciphisa i-phosphomolybdic acid; isetshenziselwa ukuthola i-antimony, i-barium, i-bismuth, i-calcium, i-cerium, ithusi, njll.; isetshenziselwa ukuthola i-phosphorus, i-nitrite, isiliva, i-thorium, i-titanium, njll.
I-phenolic acid encibilika emanzini, etholakala emaqabunga amagilebhisi nasezitshalweni eziningi, iyi-antioxidant esebenzayo ye-in vitro.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
