Glycine

Glycine(chidule cha Gly), chomwe chimatchedwanso acetic acid, ndi amino acid osafunikira, mankhwala ake ndi C2H5NO2.Glycine ndi amino acid ya endogenous antioxidant yochepetsera glutathione, yomwe nthawi zambiri imawonjezeredwa ndi magwero akunja pamene thupi liri ndi nkhawa kwambiri. , ndipo nthawi zina amatchedwa theka-ofunika amino acid.Glycine ndi imodzi mwa amino zidulo zosavuta.

Chemical katundu:

White monoclinic kapena hexagonal crystal, kapena ufa woyera wa crystalline.Zopanda fungo, ndi kukoma kwapadera kokoma.Mosavuta sungunuka m'madzi, kusungunuka m'madzi: 25g/100ml pa 25 ℃;Pa 50 ℃, 39.1g/10Chemicalbook0ml;54.4g/100ml pa 75 ℃;Pa 100 ℃, ndi 67.2g/100ml.Mowa kwambiri wosasungunuka, pafupifupi 0.06g kusungunuka mu 100g anhydrous ethanol.Pafupifupi osasungunuka mu acetone ndi ether.

Njira yopangira:

Njira ya Strecker ndi njira ya chloro-acetic acid ammonification ndiyo njira zazikulu zokonzekera.

Njira ya Strecker:formaldehyde, sodium cyanide, ammonium koloide anachita pamodzi, ndiye kuwonjezera glacial acetic acid, mpweya wa methylene aminoacetonitrile;Amino acetonitrile sulfate inapezedwa powonjezera methylene acetonitrile ku ethanol pamaso pa sulfuric acid.Sulfate imawonongeka ndi barium hydroxide kuti ipeze mchere wa glycine barium;Kenako sulfuric acid imawonjezeredwa kuti ipangitse barium, kusefa, kuyika kwambiri filtrate, ndipo ikazizilitsa imatulutsa makhiristo a glycine.Kuyesera [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] - (2CONH2CH2CH2CH2CH) - (NH2CH2CN) 2 ba [- H2SO4] – > H2NCH2COOH

Chloro-acetic acid ammoniation njira:ammonia madzi ndi ammonium bicarbonate wosanganiza Kutentha kwa 55 ℃, kuwonjezera chloro-acetic asidi amadzimadzi njira, anachita kwa 2h, ndiye Kutentha kwa 80 ℃ kuchotsa otsalira ammonia, decolorization ndi adamulowetsa mpweya, kusefera.The decolorizing njira anawonjezera ndi 95% Mowa kuti glycine crystallize kunja, wosefedwa, kutsukidwa Mowa ndi zouma kuti yaiwisi mankhwala.Sungunulani mu madzi otentha ndi recrystallize ndi Mowa kupeza glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] - > [NH4OH]

Kuphatikiza apo, glycine amachotsedwanso ku silika hydrolyzate ndi hydrolyzed ndi gelatin ngati zopangira.

Ntchito:

Munda wa chakudya

1, yomwe imagwiritsidwa ntchito ngati ma reagents am'chilengedwe, imatha kugwiritsidwanso ntchito ngati mankhwala, chakudya ndi zowonjezera zakudya, mafakitale a feteleza a nayitrogeni omwe amagwiritsidwa ntchito ngati wothandizila wopanda poizoni wa decarbonizing;

2, yomwe imagwiritsidwa ntchito ngati chowonjezera chopatsa thanzi, chomwe chimagwiritsidwa ntchito makamaka pazokometsera ndi zina;

3, ili ndi zoletsa zina pa kubalana kwa subtilis ndi Escherichia coli, kotero chitha kugwiritsidwa ntchito ngati chosungira zinthu za surimi, batala la mtedza, ndi zina, kuwonjezera 1% ~ 2%;

4, ali ndi antioxidant zotsatira (pogwiritsa ntchito zitsulo chelate mgwirizano), anawonjezera zonona, tchizi, margarine akhoza kuwonjezera moyo yosungirako 3 ~ 4 zina;

5. Kuti mukhazikike mafuta anyama muzowotcha, shuga 2.5% ndi glycine 0.5% akhoza kuwonjezeredwa;

6. Onjezani 0.1% ~ 0.5% ku ufa wa tirigu kuti muphike mwachangu Zakudyazi, zomwe zimatha kuchita nawo zokometsera nthawi imodzi;

7, kukoma kwa mchere ndi viniga akhoza kugwira ntchito yotchinga, kuchuluka kwa anawonjezera mchere mankhwala 0,3% ~ 0,7%, asidi mankhwala 0,05% ~ 0,5%;

8, malinga ndi malamulo athu a GB2760-96 angagwiritsidwe ntchito ngati zonunkhira.

Munda waulimi

1. Amagwiritsidwa ntchito kwambiri ngati chowonjezera komanso chokopa kuti awonjezere ma amino acid muzakudya za nkhuku, ziweto, makamaka ziweto.Ntchito ngati hydrolyzed mapuloteni zowonjezera, monga synergistic wothandizila wa hydrolyzed mapuloteni;

2, popanga mankhwala ophera tizilombo omwe amagwiritsidwa ntchito popanga pyrethroid insecticide wapakatikati wa glycine ethyl ester hydrochloride, amathanso kupangidwa ndi fungicide isobiurea ndi herbicide olimba glyphosate.

Munda wa mafakitale

1, yogwiritsidwa ntchito ngati zowonjezera zowonjezera;

2, yogwiritsidwa ntchito m'makampani opanga mankhwala, mayeso a biochemical ndi organic synthesis;

3, ntchito ngati cephalosporin zopangira, sulfoxamycin wapakatikati, imidazolacetic acid kaphatikizidwe wapakatikati, etc.;

4, amagwiritsidwa ntchito ngati zodzikongoletsera zopangira.

Kunyamula katundu: 25kg / thumba

yosungirako ayenera kukhala ozizira, youma ndi mpweya wabwino.
