Glycine

Glycine(yakapfupikiswa Gly), inozivikanwawo seacetic acid, isiri yakakosha amino acid, chimiro chayo chemakemikari ndeye C2H5NO2.Glycine is amino acid ye endogenous antioxidant yakaderedzwa glutathione, iyo inowanzowedzerwa ne exogenous zvinyorwa kana muviri uri pasi pekunetseka kwakanyanya. , uye dzimwe nguva inonzi semi-inokosha amino acid.Glycine imwe yeamino acids iri nyore.

Chemical properties:

White monoclinic kana hexagonal crystal, kana white crystalline powder.Kusanhuwa, nekunaka kunotapira.Zviri nyore soluble mumvura, solubility mumvura: 25g/100ml pa25 ℃;Pa50℃, 39.1g/10Chemicalbook0ml;54.4g/100ml pa75℃;Pa100 ℃, iri 67.2g/100ml.Yakanyanya kusanyungudika mu ethanol, ingangoita 0.06g yakanyungudika mu100g anhydrous ethanol.Inenge isinganyungudika muacetone uye ether.

Nzira yekugadzira:

Strecker nzira uye chloro-acetic acid ammonification nzira ndiyo nzira huru dzekugadzirira.

Strecker nzira:formaldehyde, sodium cyanide, ammonium chloride reaction pamwe chete, wobva wawedzera glacial acetic acid, kunaya kwemethylene aminoacetonitrile;Amino acetonitrile sulfate yakawanikwa nekuwedzera methylene acetonitrile kune ethanol muhupo hwe sulfuric acid.Iyo sulfate yakasvibiswa nebarium hydroxide kuwana glycine barium munyu;Zvadaro sulfuric acid inowedzerwa kuti iwedzere barium, iisefa, kuisa pfungwa kune filtrate, uye mushure mekutonhodza iyo inogadzirisa glycine makristasi.Kuedza [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BHemicalbooka (OH) 2] – (NH2CH2CH2CH2CH2) 2 ba [- H2SO4] – > H2NCH2COOH

Chloro-acetic acid ammoniation nzira:ammonia mvura uye ammonium bicarbonate yakasanganiswa kudziyisa kusvika ku55 ℃, ichiwedzera chloro-acetic acid aqueous solution, reaction for 2h, wozodziya kusvika 80 ℃ kubvisa yasara ammonia, decolorization ine activated carbon, filtration.Iyo decolorizing solution yakawedzerwa ne95% ethanol kuita kuti glycine ibude, yakasefa, yakagezwa ne ethanol uye yakaomeswa kuti iwane chigadzirwa chisina kuchena.Dissolve mumvura inopisa uye dzokorora ne ethanol kuti uwane glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Mukuwedzera, glycine inotorwawo kubva kusilika hydrolyzate uye hydrolyzed negelatin seyakagadzirwa.

Application:

Munda wekudya

1, inoshandiswa se biochemical reagents, inogona zvakare kushandiswa mumishonga, chikafu uye chikafu chekuwedzera, nitrogen fetiraiza indasitiri inoshandiswa seisina-chepfu decarbonizing agent;

2, inoshandiswa sekuwedzera kwekudya kunovaka muviri, inonyanya kushandiswa pakudyara uye zvimwe zvinhu;

3, ine imwe inhibitory mhedzisiro pakubereka kwe subtilis uye Escherichia coli, saka inogona kushandiswa sekuchengetedza kune zvigadzirwa zve surimi, peanut butter, nezvimwewo, wedzera 1% ~ 2%;

4, ine antioxidant mhedzisiro (ichishandisa simbi yayo chelate kubatirana), yakawedzerwa kukirimu, chizi, majarini inogona kuwedzera hupenyu hwekuchengetedza 3 ~ 4 nguva;

5. Kudzikamisa mafuta emafuta mumidziyo yakabikwa, glucose 2.5% uye glycine 0.5% inogona kuwedzerwa;

6. Wedzera 0.1% ~ 0.5% kune hupfu hwegorosi yekukurumidza kubika noodles, iyo inogona kuita basa rekudya panguva imwe chete;

7, kuravira kwemunyu nevhiniga kunogona kuita basa rebuffer, huwandu hwezvigadzirwa zvemunyu zvakawedzerwa 0.3% ~ 0.7%, asidhi zvigadzirwa 0.05% ~ 0.5%;

8, maererano nemirairo yedu GB2760-96 inogona kushandiswa sezvinonhuwira.

Munda wekurima

1. Inonyanya kushandiswa sechinhu chinowedzera uye chinokwezva kuwedzera amino acids mukudya kwehuku, zvipfuwo, kunyanya mhuka dzinovaraidza.Inoshandiswa se hydrolyzed protein additive, se synergistic agent ye hydrolyzed protein;

2, mukugadzirwa kwemishonga yezvipembenene inoshandiswa mukugadzirwa kwepyrethroid insecticide yepakati glycine ethyl ester hydrochloride, inogona zvakare kugadzirwa fungicide isobiurea uye herbicide yakasimba glyphosate.

Industrial field

1, inoshandiswa seplating solution additive;

2, inoshandiswa muindasitiri yemishonga, biochemical bvunzo uye organic synthesis;

3, inoshandiswa secephalosporin raw materials, sulfoxamycin yepakati, imidazolacetic acid synthesis yepakati, nezvimwewo;

4, inoshandiswa se cosmetic raw materials.

Chigadzirwa Packaging: 25kg / bhegi

Kuchengetera kunofanirwa kunge kuchitonhorera, kuoma uye kufefetera.
