Zoo DL Tartaric acid CAS 133-37-9
Tartaric acid yog dawb crystalline organic acid uas tshwm sim nyob rau hauv ntau cov nroj tsuag, tshwj xeeb tshaj yog nyob rau hauv grapes. Nws cov ntsev, potassium bitartrate, feem ntau hu ua qab zib ntawm tartar, tsim ib txwm nyob rau hauv cov txheej txheem ntawm winemaking. Nws yog feem ntau tov nrog sodium bicarbonate thiab yog muag raws li ci hmoov siv los ua ib tug leavening tus neeg sawv cev hauv kev npaj zaub mov. Cov kua qaub nws tus kheej tau ntxiv rau cov khoom noj ua antioxidant thiab muab nws cov qaub saj txawv.
Siv nyob rau hauv kev tsim cov ntsev tartrate, siv los ua pH stabilizer hauv electroplating, siv los ua cov kua qaub hauv kev lag luam zaub mov, feem ntau yog siv los ua tus neeg sawv cev hauv kev lag luam, thiab tseem siv tshuaj.
Siv raws li kev sim reagent, tus neeg saib xyuas daim npog ntsej muag thiab tus neeg sawv cev npias foaming, kuj siv hauv kev lag luam tanning
Siv Nws yog dav siv hauv cov khoom noj, tshuaj, tshuaj lom neeg, lub teeb kev lag luam thiab lwm yam lag luam. Piv txwv li, raws li npias foaming tus neeg saib xyuas, zaub mov qaub tus neeg sawv cev, tus neeg sawv cev flavoring, siv nyob rau hauv refreshing dej qab zib, khoom qab zib, kua txiv, ntses, txias tais, ci hmoov, thiab lwm yam., nws qaub saj yog 1.3 npaug ntawm citric acid, tshwj xeeb tshaj yog haum rau lub qaub saj ntawm grape kua txiv. Tus neeg saib xyuas. Nws tseem ua lub luag haujlwm tseem ceeb hauv tanning, yees duab, iav, enamel, khoom siv hauv xov tooj thiab lwm yam lag luam.
Siv raws li tus neeg sawv cev qaub, lub acidity yog 1.2 mus rau 1.3 npaug zog dua citric acid. Nws muaj siab solubility thiab muaj zog chelation muaj peev xwm rau hlau ions. Nws tuaj yeem siv rau hauv ntau yam khoom noj thiab siv rau hauv tus nqi tsim nyog raws li kev xav tau ntau lawm. Nws muaj aromatizing nyhuv ntawm cawv tab sis tsis muaj zog tshaj citric acid. Feem ntau siv ua ke nrog lwm cov organic acids xws li citric acid lossis malic acid.
Siv cov khoom no yog siv dav hauv cov khoom noj, tshuaj, tshuaj lom neeg kev lag luam, lub teeb kev lag luam thiab lwm yam lag luam. Nws yog tsuas yog siv hauv kev tsim cov ntsev tartrate xws li potassium bismuth potassium tartrate thiab sodium potassium tartrate. Nws cov ntsev yog siv rau daim iav nyiaj plating thiab kho hlau. Siv nyob rau hauv kev lag luam khoom noj khoom haus raws li npias foaming agents, zaub mov qaub tshuaj, flavoring agents, thiab lwm yam. Nws acidity yog 1.3 npaug ntawm citric acid, thiab nws yog tshwj xeeb tshaj yog haum raws li ib tug qaub neeg sawv cev rau txiv hmab txiv ntoo kua txiv. Hauv kev lag luam textile, tartaric acid yog siv los ua mordant los tswj kev tso cov tshuaj chlorine los ntawm cov hmoov bleaching. Nws yog siv nyob rau hauv cov tshuaj los tsim cinchon. Cov khoom no tau raug txheeb xyuas tias yog cov khoom noj khoom haus zoo tshaj plaws los ntawm FAO / WHO Cov Kws Tshaj Lij Pab Pawg. Nws tseem ua lub luag haujlwm tseem ceeb hauv tanning, yees duab, iav, enamel, khoom siv hauv xov tooj thiab lwm yam lag luam.
Siv cov tshuaj analytical reagents, dav siv nyob rau hauv qhov zoo thiab kev tsom xam, raws li ib tug masking neeg sawv cev, siv rau daim npog qhov ncauj, hlau, txhuas, titanium tungsten, thiab lwm yam thaum lub sij hawm los nag. Dissolve tej yam melts, sim los yog txiav txim siab poov tshuaj ntsev
