I-Glycine

I-Glycine(isifinyezo se-Gly), eyaziwa nangokuthi i-acetic acid, iyi-amino acid engabalulekile, ifomula yayo yamakhemikhali yi-C2H5NO2.I-Glycine i-amino acid ye-endogenous antioxidant encishisiwe i-glutathione, evame ukuxhaswa ngemithombo yangaphandle lapho umzimba ungaphansi kwengcindezi enkulu. , futhi ngezinye izikhathi ibizwa ngokuthi i-semi-essential amino acid.I-Glycine ingenye yama-amino acid alula.

Izakhiwo zamakhemikhali:

I-monoclinic emhlophe noma i-hexagonal crystal, noma i-white crystalline powder.Ayinaphunga, enokunambitheka okumnandi okukhethekile.Incibilika kalula emanzini, ukuncibilika emanzini: 25g/100ml ku-25℃;Ku-50℃, 39.1g/10Chemicalbook0ml;54.4g/100ml ku-75℃;Ku-100 ℃, ingu-67.2g/100ml.Ayincibiliki ngokwedlulele ku-ethanol, cishe u-0.06g encibilike ku-100g i-anhydrous ethanol.Cishe ayincibiliki ku-acetone ne-ether.

Indlela yokukhiqiza:

Indlela ye-Strecker kanye nendlela ye-chloro-acetic acid ammonification izindlela eziyinhloko zokulungiselela.

Indlela ye-Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction ndawonye, ​​bese wengeza glacial acetic acid, kwezulu methylene aminoacetonitrile;I-amino acetonitrile sulfate yatholwa ngokungeza i-methylene acetonitrile ku-ethanol lapho kukhona i-sulfuric acid.I-sulfate ichithwa yi-barium hydroxide ukuze ithole i-glycine barium usawoti;Khona-ke i-sulfuric acid yengezwa ukuze iphuze i-barium, ihlunge, igxilise i-filtrate, futhi ngemva kokupholisa idonsa amakristalu e-glycine.Ukuhlolwa [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (2CONH2CH2CH2CH2CH2CH) 2 ba [- H2SO4] – > H2NCH2COOH

Indlela ye-Chloro-acetic acid ammoniation:amanzi e-ammonia kanye ne-ammonium bicarbonate okuxutshwe ukushisa okuxubile ku-55 ℃, kwengeza isixazululo samanzi se-chloro-acetic, ukusabela kwe-2h, bese kushisisa ku-80 ℃ ukuze kukhishwe i-ammonia esele, i-decolorization nge-activated carbon, filtration.Isixazululo se-decolorizing sengezwe nge-ethanol engu-95% ukwenza i-glycine icwebezelise, ihlungwe, igezwe nge-ethanol futhi yomiswe ukuze kutholwe umkhiqizo ongahluziwe.Chaza emanzini ashisayo futhi uphinde uhlanganise ne-ethanol ukuze uthole i-glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Ngaphezu kwalokho, i-glycine iphinde ikhishwe ku-silika hydrolyzate futhi i-hydrolyzed nge-gelatin njengento eluhlaza.

Isicelo:

Inkambu yokudla

I-1, esetshenziswa njengama-reagents we-biochemical, ingasetshenziswa futhi kwezokwelapha, izithasiselo zokudla nezithasiselo zokudla, imboni yomanyolo we-nitrogen esetshenziswa njenge-ejenti engenabuthi ye-decarbonizing;

2, esetshenziswa njengesengezo sokudla okunomsoco, ikakhulukazi esetshenziselwa isinongo nezinye izici;

3, inomphumela othile wokuvimbela ekukhiqizeni kabusha kwe-subtilis ne-Escherichia coli, ngakho-ke ingasetshenziswa njengesilondolozi semikhiqizo ye-surimi, ibhotela lamantongomane, njll., engeza 1% ~ 2%;

I-4, inomphumela we-antioxidant (usebenzisa ukubambisana kwayo kwe-metal chelate), engezwe kukhilimu, ushizi, imajarini inganweba impilo yokugcina izikhathi ezi-3 ~ 4;

5. Ukuzinzisa isinqumelo ezimpahleni ezibhakiwe, i-glucose engu-2.5% kanye ne-glycine 0.5% ingangezwa;

6. Faka u-0.1% ~ 0.5% kufulawa kakolweni ukuze uthole ama-noodle okupheka ngokushesha, angadlala indima yesinongo ngesikhathi esifanayo;

7, ukunambitheka kasawoti noviniga kungadlala indima ye-buffer, inani lemikhiqizo kasawoti eyengeziwe 0.3% ~ 0.7%, imikhiqizo ye-asidi 0.05% ~ 0.5%;

8, ngokwemithetho yethu ye-GB2760-96 ingasetshenziswa njengezinongo.

Insimu yezolimo

1. Isetshenziswa kakhulu njengesithako nesiheha ukwandisa ama-amino acid ekuphakeleni kwezinkukhu, imfuyo, ikakhulukazi izilwane ezifuywayo.Isetshenziswa njengesengezo seprotheyini ye-hydrolyzed, njenge-ejenti ye-synergistic yeprotheyini ye-hydrolyzed;

2, ekukhiqizeni izibulala-zinambuzane ezisetshenziswa ekuhlanganisweni kwe-pyrethroid insecticide intermediate glycine ethyl ester hydrochloride, kungabuye kuhlanganiswe isikhunta isobiurea kanye ne-herbicide glyphosate eqinile.

Inkambu yezimboni

1, esetshenziswa njengesengezo sesisombululo sokucwenga;

2, esetshenziswa embonini yezemithi, ukuhlolwa kwamakhemikhali ezinto eziphilayo kanye nokuhlanganiswa kwezinto eziphilayo;

3, esetshenziswa njenge-cephalosporin izinto zokusetshenziswa, i-sulfoxamycin emaphakathi, imidazolacetic acid synthesis intermediate, njll.;

4, esetshenziswa njengezimonyo zokusetshenziswa.

Ukupakisha umkhiqizo: 25kg / isikhwama

Isitoreji kufanele sibe endaweni epholile, yomile futhi ikhiphe umoya.
