I-asidi yeGallic/CAS: 149-91-7
Inkcazo emfutshane:
Igama lemveliso: i-Gallic acid
Uhlobo:ZA-N
I-CAS: 149-91-7
I-MF: C7H6O5
I-MW: 170.12
ULWAKHIWO:
Uxinano:1.694
Indawo yokunyibilika: 251 °C (ngoDisemba) (elikhanyayo)
Iikristale okanye umgubo ofana nenaliti omhlophe okanye omdaka okhanyayo. Iqondo lokunyibilika: 235-240℃(ukubola). Xa ishushu ukuya kwi-100-120℃, ilahlekelwa ngamanzi ayo acwebezelayo. Xa ishushu ngaphezu kwama-200℃, ilahlekelwa yikhabhoni diokside ize yenze i-pyrogallic acid (oko kukuthi, i-triphloroglucinol). Iyanyibilika emanzini ashushu, i-ether, i-ethanol, i-acetone kunye ne-glycerol, iyanyibilika kancinci emanzini abandayo, kwaye ayinyibiliki kwi-benzene kunye ne-chloroform.

Ukusetyenziswa
I-gallic acid (GA), ekwaziwa ngokuba yi-gallnut acid, yinxalenye yeetannins ezifakwa kwi-hydrolyzable kwaye inegama lekhemikhali elithi 3,4, 5-trihydroxybenzoic acid. I-Gallic acid inomxholo ophezulu kwiti yeYunnan Pu 'er kwaye yona ngokwayo ineziphumo ezininzi zebhayoloji ezifana nokulwa neentsholongwane, ukudumba, ukudumba kunye nokulwa ne-mutagenic.
I-Gallic acid isetyenziswa kakhulu kumayeza, kwii-inki, kwiidayi, ekutyeni, kushishino lokukhanya nakwi-organic synthesis, njl. I-Gallic acid idibana nee-ion zentsimbi ezintathu ukuze zenze i-blue-black precipitate, eyimveliso eluhlaza okwesibhakabhaka-mnyama. Ikwasetyenziswa kushishino lokwenza ulusu. Ingasetyenziswa njengomphuhlisi weefoto. I-Propyl gallate yi-antioxidant kwaye ingasetyenziswa kwiioyile ezityiwayo kunye namafutha ukuthintela ukonakala kunye nokuwohloka. Kwizonyango, i-gallic acid yiarhente ye-hemostatic kunye ne-astringent, kunye ne-arritant encinci yendawo.
Inefuthe lokulwa neentsholongwane kwaye ingasetyenziselwa ukunyanga isifo segazi esibangelwa yi-bacillary. Inefuthe lokutyhafa, ukuvaleka kwegazi kunye nokulwa norhudo. Ingasetyenziswa njengesigcini-zintsholongwane. Ingasetyenziselwa ukulungiselela i-pyrogallic acid, amayeza, ii-inki, iidayi eziphakathi kunye neearhente zokulwa nokuqhuma, njl. Ikwasetyenziswa njengomphuhlisi kunye ne-analytical reagent yokufumanisa ii-inorganic acids zasimahla, i-dihydroxyacetone, ii-alkaloids kunye neesinyithi, njl.
Ingasetyenziswa njengesigcini, kwaye ingasetyenziselwa ukulungisa iidayi eziphakathi kunye nezinto ezithintela ukuqhuma, njl.
Isetyenziswa njenge-reagent yeekhemikhali
Isetyenziswa kakhulu njenge-colorant kwi-inki eluhlaza okwesibhakabhaka-mnyama. Isetyenziswa kwishishini lamayeza ukulungiselela i-sulfonamide potentiator TMP kunye ne-arhente edibanisa ii-sulfonamides ezifana ne-SMZ kunye ne-SD-ethyl. Ishishini lokutya liyisebenzisa ukulungiselela i-gallic acid egcina umswakama. Isetyenziswa kwishishini lokhuselo ukulungiselela ii-arhente ezikhusela ukuqhuma. Ukongeza, ingasetyenziswa nakwimveliso yeedayi ze-mordant kunye nomphuhlisi, njl.
Isetyenziswa njenge-depolarizer kuhlalutyo lwe-electrochemical; isetyenziselwa ukunciphisa i-phosphomolybdic acid; isetyenziselwa ukufumanisa i-antimony, i-barium, i-bismuth, i-calcium, i-cerium, i-copper, njl.njl.; isetyenziselwa ukufumanisa i-phosphorus, i-nitrite, isilivere, i-thorium, i-titanium, njl.njl.
I-phenolic acid enyibilikayo emanzini, ekhoyo kumagqabi eediliya nakwizityalo ezininzi, yi-antioxidant esebenzayo kwi-in vitro.
