Magetsi makemikari anowanzo kureva makemikari akakosha eiyo indasitiri yemagetsi. Parizvino, pane makumi ezviuru zvemarudzi, ari kukumbira zvemhando yepamusoro zvinodikanwa, zvakaderera kudyiwa, zvakakwirira zvinodiwa kune hutsanana hwechigadzirwa uye nharaunda yekushandisa uye kukwidziridza nekukurumidza .Ultra-yakachena yakachena-yakachena makemikari reagents (inozivikanwawo seMvura Mvura. , kana Maitiro Makemikari), zvakare Inhengo yakakosha kwazvo yemakemikari emakemikari, anonyanya kushandiswa kuchenesa chip (kusanganisira kuomesa), photolithography, etching, kuvandudza, kubvisa firimu, doping Miscellaneous, inosanganisira anopfuura makumi masere emakemikari chaiwo. yakakwira-yakachena acid Uye alkalis, yakasviba-yakachena uye yakachena-yakachena macolor solvents uye ultra-yakakwira-yakachena etchant. Pano tiri kuunza zvigadzirwa zvitsva zvemhuri iyi-yakakwira-yakachena gallic acid
Gallic acid (GA), inozivikanwawo se gallic acid, gallic acid, iri chena kana yakajeka yeyero tsono-yakaita sekristaro kana hupfu, zita rayo remakemikari ndiro 3,4,5-Trihydroxyl benzoic acid (3,4,5-Trihydroxyl benzoic asidhi). ), molecular fomula C7H6O5, mamorekuru uremu 170.12, kuburikidzaIyo inowanzovapo muchimiro che monohydrate ine huremu hwakakomba hwe1.694 uye nzvimbo inonyungudika ye235 kusvika 240 ° C (kuora). Kana ichipisa kusvika pa100 ~ 120 ℃, inorasikirwa neCrystal mvura: Kana ikapisa kusvika pamusoro pe200 ℃, icharasikirwa ne CO2. Inogadzira pyrocarbon GA; inonyungudika nyore nyore mumvura inopisa, ether, ethanol, acetone uye glycerin, asi yakaoma Inogadzikana mumvura inotonhorera, isina insoluble mu benzene, acetic acid uye chloroform; inouraya dose yegonzo subcutaneous jekiseni ndeye 4000mg / Kg: iyo pH kukosha kweiyo aqueous mhinduro ndeye 3 ~ 4; Iyo ine yakasimba kudzikisira, inovhenekera uye inonwisa mvura kuravira, inogona kudzora goridhe nesirivhu munyu uye mhinduro yaFehling, uye kuita ne ferric chloride kuburitsa bhuruu-dema Kunaya, parizvino yakakosha yakanaka kemikari inonyanya kugadzirwa neguru kana tara sezvinhu zvakagadzirwa.
Gallic acid ine akasiyana mafomu ekushandisa, anoshandiswa zvakanyanya mu organic synthesis, machira, madhayi, mushonga, chikafu, makemikari, kuchenesa, makemikari ezuva nezuva, kurima, zvicherwa, nezvimwe, zvinonyanya kushandiswa mukugadzira zvinodhaka, madhayi, inki, uye zvakare inoshandiswa sekudya antioxidants, zvinodzivirira, simbi inobvisa, ultraviolet absorber, disinfectants, hemostatic astringents, imaging vamiririri, makemikari reagents, madhaka fluidizing vamiririri uye mazambiringa ekukura ejenti, nezvimwe. Icho chakakosha chemakemikari ekugadzirisa zvinhu.
Mumakore achangopfuura, iyo yemagetsi makemikari giredhi uye yakakwira-yakachena gallic acid yakashandiswa muUS zvemagetsi indasitiri kugeza makuru-madiki akabatanidzwa wedunhu mabhodhi.
Unhu hwaro hunodiwa hwakanyanya kuomarara, zviratidziro zvikuru ndezvekuti: GA≥99.5%, Na, K, Fe, Cu, Pb, Al, Cr, Zn, Mn, Ni are all≤0.1 mg / kg (kureva, huwandu hwasara. yesimbi ion ndeye 1 * 10-7 danho). Naizvozvo, kubvisa trace simbi ion mu gallic acid ndeyekugadzirira kiyi kune yakachena kuchena gallic acid.
