I-Glycine

I-Glycine(efushanisiwe i-Gly), eyaziwa nangokuthi i-acetic acid, iyi-amino acid engabalulekile, ifomula yayo yamakhemikhali yi-C2H5NO2. I-Glycine iyi-amino acid ye-antioxidant engokwemvelo encishisiwe i-glutathione, evame ukwenezelwa yimithombo yangaphandle lapho umzimba ungaphansi kokucindezeleka okukhulu, futhi ngezinye izikhathi ibizwa ngokuthi i-amino acid eyisisekelo. I-Glycine ingenye yama-amino acid alula kakhulu.

Izakhiwo zamakhemikhali:

I-monoclinic emhlophe noma i-hexagonal crystal, noma i-white crystalline powder. Ayinaphunga, inokunambitheka 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 kakhulu ku-ethanol, cishe u-0.06g uncibilikiswe ku-100g anhydrous ethanol. Cishe ayincibiliki ku-acetone kanye ne-ether.

Indlela yokukhiqiza:

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

Indlela ye-Strecker:i-formaldehyde, i-sodium cyanide, i-ammonium chloride reaction ndawonye, ​​bese kungezwa i-glacial acetic acid, ukuna kwe-methylene aminoacetonitrile; I-Amino acetonitrile sulfate itholakale ngokungeza i-methylene acetonitrile ku-ethanol lapho kukhona i-sulfuric acid. I-sulfate ibola yi-barium hydroxide ukuze kutholakale usawoti we-glycine barium; Bese kufakwa i-sulfuric acid ukuze kunyatheliswe i-barium, kuhlungwe, kugxilwe ku-filtrate, futhi ngemva kokupholisa kunyatheliswe amakristalu e-glycine. Ukuhlolwa [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Indlela ye-ammoniation ye-chloro-acetic acid:amanzi e-ammonia kanye ne-ammonium bicarbonate exubile ukushisa kufinyelele ku-55℃, kufakwe isisombululo samanzi se-chloro-acetic acid, ukusabela amahora ama-2, bese kufudunyezwa kufinyelele ku-80℃ ukususa i-ammonia esele, ukususwa kombala nge-activated carbon, ukuhlunga. Isixazululo sokususa umbala senezelwe nge-95% ethanol ukwenza i-glycine ikhanye, ihlungwe, igezwe nge-ethanol bese yomiswa ukuze kutholakale umkhiqizo ongahluziwe. Ncibilikisa emanzini ashisayo bese uphinde uvuselele nge-ethanol ukuze kutholakale i-glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Ngaphezu kwalokho, i-glycine ikhishwa ku-silk hydrolyzate bese ifakwa i-hydrolyzed nge-gelatin njengezinto zokusetshenziswa.

Isicelo:

Insimu yokudla

1, esetshenziswa njengezinto zokwenza izinto ngamakhemikhali, ingasetshenziswa kwezokwelapha, ukudla kanye nezithasiselo zokudla, imboni yomanyolo we-nitrogen esetshenziswa njenge-ejenti yokususa i-carbon dioxide engenabo ubuthi;

2, esetshenziswa njengesengezo sokudla okunempilo, esetshenziswa kakhulu ekunongeni nezinye izici;

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

4, inomphumela we-antioxidant (ngokusebenzisa ukubambisana kwayo kwe-chelate yensimbi), uma ingezwe kukhilimu, ushizi, imajarini ingandisa impilo yokugcina izikhathi ezi-3 ~ 4;

5. Ukuze kuqiniswe isiraphu ezitsheni ezibhakiwe, kungangezwa i-glucose engu-2.5% kanye ne-glycine engu-0.5%;

6. Engeza u-0.1% ~ 0.5% kufulawa kakolweni ukuze uthole ama-noodle aphekwe ngokushesha, angadlala indima yezinongo ngesikhathi esifanayo;

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

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

Insimu yezolimo

1. Isetshenziswa kakhulu njengesithasiselo nesihehayo sokwandisa ama-amino acid ekudleni kwezinkukhu, imfuyo, ikakhulukazi izilwane ezifuywayo. Isetshenziswa njengesithasiselo seprotheyini esifakwe i-hydrolyzed, njenge-ejenti yokusebenzisana kweprotheyini efakwe i-hydrolyzed;

2, ekukhiqizweni kwezibulala-zinambuzane ezisetshenziswa ekuhlanganiseni izinambuzane ze-pyrethroid i-glycine ethyl ester hydrochloride, kungaphinde kuhlanganiswe i-fungicide isobiurea kanye ne-herbicide solid glyphosate.

Insimu yezimboni

1, esetshenziswa njengesixazululo sokufaka i-plating;

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

3, esetshenziswa njengezinto zokusetshenziswa ze-cephalosporin, i-sulfoxamycin ephakathi, i-imidazolacetic acid synthesis ephakathi, njll.;

4, esetshenziswa njengezinto zokusetshenziswa zokuhlobisa.

Ukupakisha Komkhiqizo: 25kg/isikhwama

Indawo yokugcina kufanele ibe pholile, yomile futhi ifake umoya.
