nkhani

Asidi wa Glyoxylic CAS 298-12-4, ili ndi fomula ya molekyulu ya C₂H₂O₃ ndi kulemera kwa molekyulu ya 74.04. Yankho lake lamadzi ndi madzi owonekera opanda mtundu, osungunuka pang'ono mu ethanol, ether ndi benzene.

Glyoxylic acidndi chinthu chofunikira chachilengedwe, chomwe chili ndi gulu la aldehyde (-CHO) ndi gulu la carboxyl (-COOH), lomwe lili ndi kapangidwe ka HOCCOOH. Lili ndi zinthu zosiyanasiyana zakuthupi ndi zamakemikolo, monga kuchuluka kwa anthu (d₂₀₄) kwa 1.384, chizindikiro cha refractive (n₂₀D) cha 1.403, kutentha kwa 111°C, kutentha kwa -93°C, kutentha kwa 103.9°C, ndi kuthamanga kwa nthunzi kwa 0.0331mmHg pa 25°C. Limawoneka ngati makhiristo oyera okhala ndi fungo losasangalatsa. Yankho lake lamadzi ndi madzi opanda mtundu kapena achikasu owala, omwe sangasungunuke mu ether, ethanol ndi benzene. Limatha kuyamwa chinyezi ndikukhala slurry pakapita nthawi yochepa litakhala ndi mpweya, ndipo limawononga.

Asidi wa Glyoxylic CAS 298-12-4ali ndi ntchito zosiyanasiyana m'magawo osiyanasiyana:

Gawo la zokongoletsa:Glyoxylic acidimagwiritsidwa ntchito ngati chopangira zonunkhira komanso chopangira zodzoladzola m'munda wa zodzoladzola.

Gawo la mankhwala:Glyoxylic acid ndi chinthu chopangidwa ndi mankhwala ophera tizilombo monga atenolol ndi Dp-hydroxyphenylglycine. Glyoxylic acid ingagwiritsidwe ntchito popanga penicillin wa pakamwa, allantoin, p-hydroxyphenylglycine, p-hydroxyphenylacetic acid, mandelic acid, acetophenone, α-thiophene glycolic acid, p-hydroxyphenylacetamide (mankhwala a mtima ndi kuthamanga kwa magazi monga atenolol). Nthawi yomweyo, imagwiritsidwa ntchito popanga mankhwala ophera zilonda zam'mimba monga capsule ndi allantoin.

Ulimi:Asayansi apanga pulasitiki yochokera ku biomass kuti ilowe m'malo mwa pulasitiki yachikhalidwe. Pulasitiki yatsopanoyi imapangidwa ndi mankhwala otsika mtengo, momwe glyoxylic acid imatha kuyika mamolekyu a shuga ndi magulu "omata" kuti agwire ntchito ngati pulasitiki yomangira. Mu gawo laulimi, pulasitiki yatsopanoyi ingagwiritsidwe ntchito pazinthu zosiyanasiyana monga ma CD, nsalu, mankhwala, ndi zinthu zamagetsi.

Chitetezo cha chilengedwe:Kayendedwe ka glyoxylate n'kofunika kwambiri m'munda wa biochemistry. Makamaka m'malo opanda kuwala, zomera zimatha kusintha mafuta acid kukhala shuga kudzera mu kayendedwe ka glyoxylate kuti zisunge mphamvu ndi mpweya wofunikira kuti zikule, zilimbikitse kayendedwe ka zinthu za chilengedwe, komanso kukulitsa luso lotha kusintha zinthu m'malo ovuta monga chilala ndi mchere wambiri.

UnilongndiGlyoxylic acid CAS 298-12-4 yaukadaulo wopanga, titha kupereka mitundu yosiyanasiyana ya zinthu zomweUkadaulo Wachilengedwe, chitsimikizo cha khalidwe, kutumiza mwachangu, muli nazo zonse. Ngati mukufuna, chondeLumikizanani nafe.
