Taurine (CAS: 107-35-7) JP Tikanga Whakamātautau
Ko te Taurine, ina whakamaroke, kaua e iti iho i te 99.0% me te kore e neke ake i te 101.0% o C2H7NO3S.
Whakaahuatanga Ko te Taurine ka puta he tioata kore tae, he ma, he paura tioata ma ranei.
He memeha ki te wai, karekau e rewa ki te waiwaro (99.5).
Kei waenganui i te 4.1 me te 5.6 te pH o te wairewa i mahia ma te whakakore i te 1.0 karae o Taurine ki te 20 mL o te wai katahi ano ka kohuatia me te wai whakamatao.
Te Tautuhinga Whakatauhia te tuāwhiorangi whakauru infrared o Taurine kia rite ki te tohutohu i te tikanga kōpae pāhare pāporo bromide i raro i te Spectrophotometry Infrared <2.25>, ka whakatairitehia te tūāwhiorangi ki te Tūāwhiorangi Tohutoro: e whakaatu ana ngā tūāwhiorangi e rua i te kaha o te whakaurunga i te tau ngaru kotahi.
Te Maama (1) Te marama me te tae o te otinga-Ko te otinga ka puta ma te whakakore i te 1.0 g Taurine i roto i te 20 mL wai he maamaa me te kore tae.
(2) Chloride <1.03>-Mahia te whakamatautau me te 1.0 g Taurine.Whakapaia te otinga whakahaere me te 0.30 mL o te 0.01mol/L waikawa pūhaumāota VS (kaua e neke ake i te 0.011%).

(4) Ammonium <1.02>-Mahia te whakamatautau me te 0.25 g o Taurine.Whakapaia te otinga mana me te 5.0 mL o te Waihanga Haukini Paerewa (kaua e neke ake i te 0.02%).
(5) Nga konganuku taumaha <1.07>-Haere ki te 2.0 g Taurine kia rite ki te Tikanga 1, ka mahia te whakamatautau.Whakapaia te otinga mana me te 2.0 mL o te Wairewa Aratohu Paerewa (kaua e neke ake i te 10 ppm).
(6) Rino <1.10>-Whakaritea te otinga whakamatautau me te 2.0 g o Taurine kia rite ki te Tikanga 1, me te mahi i te whakamatautau kia rite ki te Tikanga A. Whakaritea te otinga whakahaere me te 2.0 mL o te Paerewa Iron Solution (kaua e neke atu i te 10 ppm).
(7) Nga matū e pa ana-Whakarewahia te 1.0 g Taurine ki te 50 mL wai, ka whakamahi i tenei otinga hei tauira otinga.Pipeto 1 mL o te tauira otinga, ka tapirihia he wai kia 50 mL.Pipeto 1 mL o tenei wairewa, tapirihia he wai kia rite ki te 10 mL, ka whakamahi i tenei otinga hei otinga paerewa.Mahia te whakamatautau me enei rongoatanga pera i te whakahau i raro i te Thin-layer Chromatography <2.03>.Tuhia te 5mL o ia tauira otinga me te otinga paerewa ki runga i te pereti kirikiri mo te chromatography paparanga angiangi.Whakawhanakehia te pereti me te ranunga o te wai, te waiwaro (99.5), te 1-butanol me te waikawa acetic (100) (150:150:100:1) ki te 10 cm te tawhiti, ka whakamaroke-rangi te pereti.Ringihia te ninhydrin-butanol TS ki runga i te pereti, ka whakamahana i te 105 ℃ mo te 5 meneti: ko te waahi i tua atu i te waahi kaupapa me te otinga tauira kaua e neke ake i te waahi kotahi, a kaore i te kaha ake i te waahi me te otinga paerewa. .
Ngaronga i te whakamaroke <2.41> Kaua e neke ake i te 0.20% (1 g, 105℃, 2 haora).
Te toenga i runga i te mura <2.44>Kaua e neke ake i te 0.1% (1 g).
Whakamaatau Kia tika te pauna mo te 0.2 g Taurine, kua maroke i mua, memeha ki te 50 mL wai, tāpirihia te 5 mL o te wairewa formaldehyde, me te titrate<2.50>me te 0.1 mol/L konutai waihā VS (potentiometric titration).Kia rite tonu te mahi i tetahi whakatau paatea, me te whakatika i nga mea e tika ana.
Ia mL o te 0.1 mol/L konutai waihā VS ＝12.52 mg o C2H7NO3S
Ipu me te rokirokiContainers-He ipu kua kati pai.
