Taurine (CAS: 107-35-7) Keʻano ho'āʻo JP
ʻO Taurine, ke maloʻo, ʻaʻole i emi iho ma lalo o 99.0% a ʻaʻole ʻoi aku ma mua o 101.0% o C2H7NO3S.
Hōʻike ʻia ʻo Taurine e like me ke kala kala ʻole a keʻokeʻo paha, a i ʻole ka pauka crystalline keʻokeʻo.
Hiki ke hoʻoheheʻe ʻia i ka wai, a hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol (99.5).
ʻO ka pH o kahi hopena i hoʻomākaukau ʻia ma ka hoʻoheheʻe ʻana i 1.0 g Taurine i 20 mL o ka wai i hoʻolapalapa hou ʻia a me ka wai maʻalili ma waena o 4.1 a me 5.6.
Identification E hoʻoholo i ka spectrum absorption infrared o Taurine e like me ke kuhikuhi ʻana ma ke ʻano pāpaʻa bromide disk ma lalo o Infrared Spectrophotometry <2.25>, a hoʻohālikelike i ke kikoʻī me ka Spectrum Reference: hōʻike nā kikoʻī ʻelua i ka ikaika o ka absorption ma nā helu nalu like.
Maʻemaʻe (1) Ka māmā a me ka waihoʻoluʻu o ka hāʻina-ʻO kahi hopena i loaʻa ma ka hoʻoheheʻe ʻana i 1.0 g o Taurine i loko o 20 mL o ka wai he akaka a kala ʻole.
(2) Chloride <1.03>-E hana i ka ho'āʻo me 1.0 g o Taurine.E hoʻomākaukau i ka hopena hoʻomalu me 0.30 mL o 0.01mol/L hydrochloric acid VS (ʻaʻole ʻoi aku ma mua o 0.011%).

(5) Nā metala kaumaha <1.07>-E hoʻomau me 2.0 g o Taurine e like me ke ʻano 1, a hana i ka hoʻāʻo.E hoʻomākaukau i ka hoʻonā hoʻomalu me 2.0 mL o ka mea hoʻonā alakaʻi maʻamau (ʻaʻole ʻoi aku ma mua o 10 ppm).
(6) Hao <1.10>-E hoʻomākaukau i ka hopena ho'āʻo me 2.0 g o Taurine e like me keʻano 1, a hana i ka ho'āʻo e like me keʻano A. E hoʻomākaukau i ka hopena mana me ka 2.0 mL o ka Iron Solution (ʻaʻole iʻoi aku ma mua o 10 ppm).
(7) Nā mea pili-E hoʻoheheʻe i 1.0 g o Taurine i 50 mL o ka wai, a e hoʻohana i kēia haʻina e like me ka hāpana hāpana.Pipet 1 mL o ka hāpana hāpana, a hoʻohui i ka wai i 50 mL pono.Pipet 1 mL o kēia haʻina, e hoʻohui i ka wai e hana pono i 10 mL, a e hoʻohana i kēia haʻina e like me ka hopena maʻamau.E hana i ka ho'āʻo me kēia mau haʻina e like me ka kuhikuhi ʻana ma lalo o Thin-layer Chromatography <2.03>.E kau i 5mL o kēlā me kēia hāpana hāpana a me ka hoʻonā maʻamau ma luna o kahi pā silica gel no ka chromatography ʻāpana lahilahi.E hoʻomohala i ka pā me ka hui ʻana o ka wai, ethanol (99.5), 1-butanol a me ka acetic acid (100) (150:150:100:1) i kahi mamao o 10 knm, a maloʻo i ka pā.E pīpī pono i ka ninhydrin-butanol TS ma ka pā, a me ka wela ma 105 ℃ no 5 mau minuke: ʻo kahi ʻē aʻe ma mua o ka wahi kumu me ka hāpana hāpana ʻaʻole i ʻoi aku ma mua o hoʻokahi wahi, a ʻaʻole i ʻoi aku ka ikaika ma mua o ka wahi me ka hopena maʻamau. .
ʻAʻole i ʻoi aku ma mua o 0.20% (1 g, 105℃, 2 hola).
Ke koena ma ka ʻā ʻana <2.44>ʻAʻole i ʻoi aku ma mua o 0.1% (1 g).
E kaupaona pololei ma kahi o 0.2 g o Taurine, i maloʻo mua, e hoʻoheheʻe i loko o 50 mL o ka wai, e hoʻohui i 5 mL o ka solution formaldehyde, a e titrate<2.50>me 0.1 mol/L sodium hydroxide VS (potentiometric titration).E hana i kahi hoʻoholo hakahaka ma ke ʻano like, a hana i nā hoʻoponopono e pono ai.
ʻO kēlā me kēia mL o 0.1 mol/L sodium hydroxide VS ＝12.52 mg o C2H7NO3S
ʻO nā pahu a me ka waiho ʻana i nā pahu pahu-paʻa maikaʻi.
