Taurine CAS 107-35-7 Assay 99.0 ~ 101.0% Factory High Quality

Taurine (CAS: 107-35-7) Njira Yoyesera ya JP
Taurine, ikauma, imakhala ndi osachepera 99.0% komanso osapitirira 101.0% ya C2H7NO3S.
Kufotokozera Taurine imapezeka ngati makristasi opanda mtundu kapena oyera, kapena ufa wa crystalline woyera.
Imasungunuka m'madzi, ndipo imakhala yosasungunuka mu ethanol (99.5).
PH ya yankho lokonzedwa mwa kusungunula 1.0 g ya Taurine mu 20 mL ya madzi owiritsa kumene ndi ozizira ndi pakati pa 4.1 ndi 5.6.
Chizindikiritso Dziwani kuchuluka kwa mayamwidwe a infrared a Taurine monga momwe amayankhidwira mu njira ya potassium bromide disk pansi pa Infrared Spectrophotometry <2.25>, ndikuyerekeza mawonekedwewo ndi Reference Spectrum: mawonekedwe onsewa amawonetsa kulimba kofanana kwa mayamwidwe amtundu womwewo.
Chiyero (1) Kumveka bwino ndi mtundu wa yankho - Yankho lomwe limapezeka posungunula 1.0 g wa Taurine mu 20 ml ya madzi ndi lomveka komanso lopanda mtundu.
(2) Chloride <1.03>-Yesani mayeso ndi 1.0 g ya Taurine.Konzani njira yowongolera ndi 0.30 mL ya 0.01mol/L hydrochloric acid VS (osapitirira 0.011%).
(3) Sulfate <1.14>-Chitani mayeso ndi 2.0 g ya Taurine.Konzani njira yowongolera ndi 0.40 mL ya 0.005 mol/L sulfuric acid VS (osapitirira 0.010%).
(4) Ammonium <1.02>-Yesani mayeso ndi 0.25 g ya Taurine.Konzani njira yowongolera ndi 5.0 mL ya Standard Ammonium Solution (osapitirira 0.02%).
(5) Zitsulo zolemera <1.07>-Pitirizani ndi 2.0 g ya Taurine molingana ndi Njira 1, ndikuchita mayeso.Konzani njira yowongolera ndi 2.0 mL ya Standard Lead Solution (osapitirira 10 ppm).
(6) Iron <1.10> -Konzani njira yothetsera mayesero ndi 2.0 g ya Taurine molingana ndi Njira 1, ndikuyesani molingana ndi Njira A. Konzani njira yothetsera vutoli ndi 2.0 mL ya Standard Iron Solution (osapitirira 10 ppm).
(7) Zogwirizana nazo-Sungani 1.0 g ya Taurine mu 50 ml ya madzi, ndipo gwiritsani ntchito yankholi ngati njira yothetsera.Pipeni 1 mL yachitsanzo, ndikuwonjezera madzi kuti mupange 50 ml ndendende.Pipeni 1 ml ya yankho ili, onjezerani madzi kuti mupange 10 ml ndendende, ndipo gwiritsani ntchito yankholi ngati yankho lokhazikika.Chitani mayeso ndi mayankho awa monga momwe akuwongolera pansi pa Thin-layer Chromatography <2.03>.Malo 5mL iliyonse ya yankho lachitsanzo ndi yankho lokhazikika pa mbale ya silika gel osakaniza chromatography.Kupanga mbale ndi osakaniza madzi, Mowa (99.5), 1-butanol ndi asidi asidi (100) (150:150:100:1) kwa mtunda wa pafupifupi 10 cm, ndi mpweya wowumitsa mbale.Utsi wogawana ninhydrin-butanol TS pa mbale, ndi kutentha pa 105 ℃ kwa mphindi 5: malo ena osati mfundo malo ndi yankho chitsanzo si oposa malo amodzi, ndipo si kwambiri kuposa malo ndi njira muyezo. .
Kutaya pa kuyanika <2.41> Osapitirira 0.20% (1 g, 105 ℃, 2 hours).
Zotsalira pakuyatsa <2.44>Osapitirira 0.1% (1 g).
Kuyesa Kuyeza molondola za 0.2 g ya Taurine, yowumitsidwa kale, sungunuka mu 50 mL ya madzi, kuwonjezera 5 mL ya formaldehyde solution, ndi titrate<2.50>ndi 0.1 mol/L sodium hydroxide VS (potentiometric titration).Chitani chitsimikiziro chopanda kanthu mwanjira yomweyo, ndipo pangani kukonza kulikonse kofunikira.
ML iliyonse ya 0.1 mol/L sodium hydroxide VS ＝12.52 mg ya C2H7NO3S
Zotengera ndi zosungira - Zotengera zotsekedwa bwino.
