Nzvimbo yekunyunguduka: 251 °C (Zvita) (yakapfava)
Makristaro kana upfu hwakaita setsvimbo chena kana chebrown chakareruka. Nzvimbo yekunyunguduka: 235-240℃(kuora). Kana yapiswa kusvika pa100-120℃, inorasikirwa nemvura yayo yakaita sekristaro. Kana yapiswa pamusoro pe200℃, inorasikirwa necarbon dioxide yogadzira pyrogallic acid (kureva, triphloroglucinol). Inonyungudika mumvura inopisa, ether, ethanol, acetone uye glycerol, inonyungudika zvishoma mumvura inotonhora, uye hainyungudike mubenzene nechloroform.

Kushandiswa
Gallic acid (GA), inozivikanwawo se gallnut acid, chikamu chematannins anonyungudika uye ine zita remakemikari rekuti 3,4, 5-trihydroxybenzoic acid. Gallic acid ine huwandu hwakawanda muYunnan Pu 'er tea uye pachayo ine mhedzisiro yakawanda yehupenyu senge antibacterial, anti-inflammatory, anti-bumor uye anti-mutagenic.
Gallic acid inoshandiswa zvakanyanya mumishonga, inki, madhayi, chikafu, indasitiri yechiedza uye organic synthesis, nezvimwewo. Gallic acid inoshanda nemaion esimbi matatu kuti igadzire bhuruu-dema precipitate, inova chinhu chekugadzira inki yebhuruu-dema. Inoshandiswawo mumaindasitiri ekugadzira dehwe. Inogonawo kushandiswa semugadziri wemifananidzo. Propyl gallate iantioxidant uye inogona kushandiswa mumafuta anodyiwa nemafuta kudzivirira kuora nekuora. Mukurapa, gallic acid imushonga we hemostatic uye astringent, pamwe nekuderedza kushatirwa kwenzvimbo.
Ine simba rekurwisa mabhakitiriya uye inogona kushandiswa kurapa manyoka emudumbu. Ine simba rekudzivirira kutsvuka kweropa, hemostatic uye antidiarrheal. Inogona kushandiswa semushonga wekuchengetedza. Inogona kushandiswa kugadzira pyrogallic acid, mishonga, inks, madhayi epakati uye mishonga inodzivirira kuputika, nezvimwewo. Inoshandiswawo semugadziri uye semugadziri wekuongorora wekuona ma inorganic acids, dihydroxyacetone, alkaloids nesimbi, nezvimwewo.
Inogona kushandiswa semushonga wekuchengetedza, uye inogona kushandiswa kugadzira madhayi epakati uye mishonga inodzivirira kuputika, nezvimwewo
Inoshandiswa semushonga wemakemikari
Inonyanya kushandiswa semushonga wekupenda inki yebhuruu-nhema. Inoshandiswa muindasitiri yemishonga kugadzira sulfonamide potentiator TMP uye semushonga wekuwedzera ma sulfonamides akadai seSMZ neSD-ethyl. Indasitiri yezvekudya inoishandisa kugadzira gallic acid inochengetedza. Inoshandiswa muindasitiri yezvekudzivirira kugadzira zvinhu zvinodzivirira kuputika. Pamusoro pezvo, inogona zvakare kushandiswa mukugadzira mordant dyes uye semugadziri, nezvimwewo.
Inoshandiswa se depolarizer mukuongorora kwe electrochemical; inoshandiswa kuderedza phosphomolybdic acid; inoshandiswa pakuona antimony, barium, bismuth, calcium, cerium, copper, nezvimwewo; inoshandiswa pakuona phosphorus, nitrite, sirivha, thorium, titanium, nezvimwewo.
Phenolic acid inonyungudika mumvura, iri mumashizha emazambiringa nemiti yakawanda, inodzivirira ganda kubva muzvirwere zvemuviri.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
