Glyoxylic acid CAS 298-12-4, muaj cov qauv molecular ntawm C₂H₂O₃ thiab molecular hnyav ntawm 74.04. Nws cov tshuaj aqueous yog cov kua dej tsis muaj xim, me ntsis soluble hauv ethanol, ether thiab benzene.
Glyoxylic acidyog ib qho tseem ceeb ntawm cov organic compound, suav nrog ib pawg aldehyde (-CHO) thiab pawg carboxyl (-COOH), nrog cov qauv qauv ntawm HOCCOOH. Nws muaj ntau yam ntawm lub cev thiab tshuaj lom neeg, xws li tus txheeb ze ntom ntom (d₂₀₄) ntawm 1.384, qhov taw qhia tsis pom kev (n₂₀D) ntawm 1.403, qhov kub ntawm 111 ° C, melting point ntawm -93 ° C, flash point ntawm 103 aH 3.0 ° C ntawm qhov kub thiab txias. 25 ° C. Nws zoo nkaus li dawb crystals nrog ib qho tsis kaj siab tsw. Nws cov tshuaj aqueous yog cov kua tsis muaj xim lossis lub teeb daj pob tshab, uas yog insoluble hauv ether, ethanol thiab benzene. Nws tuaj yeem nqus dej noo thiab dhau los ua slurry hauv ib lub sijhawm luv luv tom qab raug huab cua, thiab corrosive.
Glyoxylic acid CAS 298-12-4muaj ntau yam kev siv hauv ntau qhov chaw:
Cosmetic teb:Glyoxylic acidyog siv los ua perfumer thiab fixative rau tshuaj pleev ib ce nyob rau hauv cosmetic teb.
Pharmaceutical teb:Glyoxylic acid yog cov khoom siv hluavtaws rau cov tshuaj intermediates xws li tshuaj tiv thaiv ntshav siab atenolol thiab Dp-hydroxyphenylglycine. Glyoxylic acid tuaj yeem siv los ua ke ntawm qhov ncauj penicillin, allantoin, p-hydroxyphenylglycine, p-hydroxyphenylacetic acid, mandelic acid, acetophenone, α-thiophene glycolic acid, p-hydroxyphenylacetamide (kab mob plawv thiab cov tshuaj ntshav siab xws li ateno). Tib lub sijhawm, nws yog siv los tsim cov tshuaj tiv thaiv kab mob xws li tshuaj ntsiav thiab allantoin.
Ua liaj ua teb:Cov kws tshawb fawb tau tsim cov khoom siv biomass los hloov cov yas qub. Cov yas tshiab no yog tsim los ntawm cov tshuaj pheej yig, uas glyoxylic acid tuaj yeem ua cov suab thaj molecules nrog "nplaum" pawg los ua lub tsev thaiv cov yas. Hauv kev ua liaj ua teb, cov yas tshiab no tuaj yeem siv rau ntau yam kev siv xws li ntim khoom, textiles, tshuaj, thiab khoom siv hluav taws xob.
Kev tiv thaiv ib puag ncig:Lub voj voog glyoxylate yog qhov tseem ceeb hauv kev ua haujlwm ntawm biochemistry. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig tsis muaj teeb pom kev zoo, cov nroj tsuag tuaj yeem hloov cov roj fatty acids rau hauv cov suab thaj los ntawm lub voj voog glyoxylate kom tswj tau lub zog thiab cov pa roj carbon qhov xav tau rau kev loj hlob, txhawb nqa cov khoom siv ntawm lub ecosystem, thiab txhim kho lub peev xwm hloov mus rau qhov chaw tsis zoo xws li drought thiab ntsev.
