Nā kristal a pauka paha e like me ke nila keʻokeʻo a ʻeleʻele paha. Wahi hoʻoheheʻe: 235-240℃(palaho). Ke hoʻomehana ʻia i 100-120℃, nalowale kona wai aniani. Ke hoʻomehana ʻia ma luna o 200℃, nalowale ia i ke kalapona ʻokikene a hana i ka waikawa pyrogallic (ʻo ia hoʻi, triphloroglucinol). He mea hoʻoheheʻe ia i ka wai wela, ether, ethanol, acetone a me glycerol, hoʻoheheʻe iki ʻia i ka wai anuanu, a ʻaʻole hoʻoheheʻe ʻia i ka benzene a me ka chloroform.

Hoʻohana
ʻO ka waikawa gallic (GA), i ʻike ʻia hoʻi ʻo ka waikawa gallnut, he ʻāpana ia o nā tannins hydrolyzable a he inoa kemika ʻo 3,4, 5-trihydroxybenzoic acid. Loaʻa i ka waikawa Gallic kahi ʻike kiʻekiʻe i loko o ke kī Yunnan Pu 'er a loaʻa iā ia nā hopena olaola he nui e like me ka antibacterial, anti-inflammatory, anti-tumor a me ka anti-mutagenic.
He nui nā hoʻohana o ka waikawa Gallic i nā lāʻau lapaʻau, nā ʻīnika, nā kala, ka meaʻai, ka ʻoihana māmā a me ka synthesis organik, a pēlā aku. Hoʻopili ka waikawa Gallic me nā ion hao trivalent e hana i kahi precipitate polū-ʻeleʻele, ʻo ia ka mea maka no ka ʻīnika polū-ʻeleʻele. Hoʻohana ʻia hoʻi ia i ka ʻoihana no ka hana ʻili. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomohala kiʻi. He antioxidant ka Propyl gallate a hiki ke hoʻohana ʻia i loko o nā aila a me nā momona ʻai e pale aku i ka palaho a me ka hōʻino ʻana. I ka lāʻau lapaʻau, he mea hemostatic a astringent ka waikawa gallic, a he mea hoʻonāukiuki kūloko iki.
Loaʻa iā ia nā hopena antibacterial a hiki ke hoʻohana ʻia e mālama i ka maʻi dysentery bacillary. Loaʻa iā ia nā hopena astringent, hemostatic a me anti-diarrheal. Hiki ke hoʻohana ʻia ma ke ʻano he mea mālama. Hiki ke hoʻohana ʻia e hoʻomākaukau i ka waikawa pyrogallic, nā lāʻau lapaʻau, nā ʻīnika, nā dyes medium a me nā mea anti-explosion, a pēlā aku. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻomohala a me kahi reagent analytical no ka ʻike ʻana i nā waikawa inorganic manuahi, dihydroxyacetone, alkaloids a me nā metala, a pēlā aku.
Hiki ke hoʻohana ʻia ma ke ʻano he mea mālama, a hiki ke hoʻohana ʻia e hoʻomākaukau i nā dyes waena a me nā mea anti-explosion, a pēlā aku
Hoʻohana ʻia ma ke ʻano he reagent kemika
Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻoluʻu no ka ʻīnika polū-ʻeleʻele. Hoʻohana ʻia ia ma ka ʻoihana lāʻau lapaʻau e hoʻomākaukau i ka sulfonamide potentiator TMP a ma ke ʻano he mea hoʻohuihui no nā sulfonamides e like me SMZ a me SD-ethyl. Hoʻohana ka ʻoihana meaʻai iā ia e hoʻomākaukau i ka waikawa gallic preservative. Hoʻohana ʻia ia ma ka ʻoihana pale e hoʻomākaukau i nā mea pale pahū. Eia kekahi, hiki ke hoʻohana ʻia i ka hana ʻana o nā dyes mordant a ma ke ʻano he mea hoʻomohala, a pēlā aku.
Hoʻohana ʻia ma ke ʻano he depolarizer i ka loiloi electrochemical; hoʻohana ʻia no ka hōʻemi ʻana i ka waikawa phosphomolybdic; hoʻohana ʻia no ka ʻike ʻana i ka antimony, barium, bismuth, calcium, cerium, keleawe, a pēlā aku; hoʻohana ʻia no ka hoʻoholo ʻana i ka phosphorus, nitrite, kālā, thorium, titanium, a pēlā aku.
ʻO ka waikawa phenolic hiki ke hoʻoheheʻe ʻia i ka wai, aia i loko o nā lau o nā hua waina a me nā mea kanu he nui, he antioxidant maikaʻi ia in vitro.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
