Glycine

Glycine. , kandi rimwe na rimwe byitwa igice cya ngombwa cya aminide acide.Glycine ni imwe muri acide yoroshye ya amino.

Ibikoresho bya shimi:

Kirisitu yera ya monoclinic cyangwa hexagonal, cyangwa ifu ya kirisiti yera.Impumuro nziza, hamwe nuburyohe budasanzwe.Kubora byoroshye mumazi, gukomera mumazi: 25g / 100ml kuri 25 ℃;Kuri 50 ℃, 39.1g / 10Igitabo cy'imiti0ml;54.4g / 100ml kuri 75 ℃;Kuri 100 ℃, ni 67.2g / 100ml.Kudashonga cyane muri Ethanol, hafi 0.06g yashonga muri 100g anhydrous Ethanol.Hafi yo kudashonga muri acetone na ether.

Uburyo bwo gukora:

Uburyo bwa Strecker hamwe na chloro-acetike acide ammonification nuburyo bwibanze bwo gutegura.

Uburyo bwa Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction hamwe, hanyuma ukongeramo acide glacial acetic, imvura ya methylene aminoacetonitrile;Amino acetonitrile sulfate yabonetse hongerwaho methylene acetonitrile kuri Ethanol imbere ya aside sulfurike.Sulfate ibora na barium hydroxide kugirango ibone umunyu wa glycine;Noneho aside sulfurike yongewemo kugirango igwe kuri barium, uyungurure, ushireho akayunguruzo, hanyuma imaze gukonjesha igwa kristu ya glycine.Ubushakashatsi [NaCN] -> [NH4Cl] CH2 = N - CH2CNCH2 = N - CH2CN [- H2SO4] -> 2 ba [- H2SO4] -> H2NCH2COOH

Uburyo bwa amloniya ya Chloro-acetike:amazi ya amoniya na ammonium bicarbonate ivanze no gushyushya kugeza kuri 55 ℃, ukongeramo aside yo mu mazi ya chloro-acetike, reaction ya 2h, hanyuma ugashyuha kuri 80 ℃ kugirango ukureho ammonia isigaye, decolorisation hamwe na karubone ikora, kuyungurura.Igisubizo cya decolorizing cyongewemo na 95% Ethanol kugirango glycine ibe hanze, kuyungurura, gukaraba hamwe na Ethanol hanyuma ikama kugirango ibone ibicuruzwa bitavanze.Kunyunyuza mumazi ashyushye hanyuma wongere ushyire hamwe na Ethanol kugirango ubone glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] -> [NH4OH]

Byongeye kandi, glycine nayo ikurwa muri silike hydrolyzate na hydrolyz hamwe na gelatine nkibikoresho fatizo.

Umurima w'ibiribwa

1, ikoreshwa nka biohimiki reagent, irashobora kandi gukoreshwa mubuvuzi, kugaburira no kongeramo ibiryo, inganda zifumbire ya azote ikoreshwa nkibikoresho bidafite ubumara bwa decarbonizing;

2, ikoreshwa nk'inyongera y'imirire, ikoreshwa cyane cyane mu birungo n'ibindi;

3, ifite ingaruka zimwe na zimwe zo kubuza kubyara subtilis na Escherichia coli, bityo rero irashobora gukoreshwa nkuburinzi bwibicuruzwa bya surimi, amavuta yintoki, nibindi, ongeramo 1% ~ 2%;

4, ifite antioxydeant (ikoresheje ubufatanye bwicyuma cya chelate), yongewe kuri cream, foromaje, margarine irashobora kongera igihe cyo kubika inshuro 3 ~ 4;

5. Guhindura lard mubicuruzwa bitetse, glucose 2,5% na glycine 0.5% birashobora kongerwamo;

6. Ongeramo 0.1% ~ 0.5% mu ifu y'ingano kugirango utekeshe vuba, bishobora kugira uruhare mugihe kimwe;

7, uburyohe bwumunyu na vinegere birashobora kugira uruhare rwa buffer, ingano yumusaruro wumunyu wongeyeho 0.3% ~ 0.7%, ibicuruzwa bya aside 0.05% ~ 0.5%;

8, dukurikije amabwiriza yacu ya GB2760-96 arashobora gukoreshwa nkibirungo.

Ubuhinzi

1. Ikoreshwa cyane cyane nk'inyongera kandi ikurura kugirango yongere aside amine mu biryo by'inkoko, amatungo, cyane cyane amatungo.Ikoreshwa nka hydrolyzed protein yongeweho, nkibikoresho bihuza poroteyine hydrolyzed;

2, mugukora imiti yica udukoko ikoreshwa muguhuza pyrethroide yica udukoko hagati ya glycine ethyl ester hydrochloride, irashobora kandi guhuzwa na fungicide isobiurea na herbicide ikomeye glyphosate.

Inganda

1, ikoreshwa nkibisubizo byongeweho;

2, ikoreshwa mu nganda zimiti, ibizamini bya biohimiki na synthesis organique;

3, ikoreshwa nkibikoresho fatizo bya cephalosporin, sulfoxamycin hagati, imidazolacetic aside synthesis hagati, nibindi.;

4, ikoreshwa nkibikoresho byo kwisiga.

Gupakira ibicuruzwa ： 25kg / igikapu
