Glyoxylic acidyog ib qho tseem ceeb organic compound, muaj ib pawg aldehyde (-CHO) thiab ib pawg carboxyl (-COOH), nrog rau cov qauv ntawm HOCCOOH. Nws muaj ntau yam khoom siv lub cev thiab tshuaj, xws li qhov ceev ntawm tus txheeb ze (d₂₀₄) ntawm 1.384, qhov ntsuas refractive (n₂₀D) ntawm 1.403, qhov kub npau ntawm 111 ° C, qhov kub yaj ntawm -93 ° C, qhov kub flash ntawm 103.9 ° C, thiab qhov siab vapor ntawm 0.0331mmHg ntawm 25 ° C. Nws zoo li cov siv lead ua dawb nrog cov ntxhiab tsw tsis zoo. Nws cov kua dej yog cov kua tsis muaj xim lossis daj daj, uas tsis yaj hauv ether, ethanol thiab benzene. Nws tuaj yeem nqus cov dej noo thiab ua slurry hauv lub sijhawm luv luv tom qab raug cua, thiab yog corrosive.
Glyoxylic acid CAS 298-12-4muaj ntau yam kev siv hauv ntau qhov chaw sib txawv:
Kev kho kom zoo nkauj:Glyoxylic acidyog siv los ua tshuaj tsw qab thiab fixative rau cov tshuaj pleev ib ce hauv kev ua kom zoo nkauj.
Kev lag luam tshuaj:Glyoxylic acid yog ib yam khoom siv raw khoom siv rau cov tshuaj intermediates xws li cov tshuaj tiv thaiv kev ntshav siab atenolol thiab Dp-hydroxyphenylglycine. Glyoxylic acid siv tau los ua cov tshuaj penicillin hauv qhov ncauj, allantoin, p-hydroxyphenylglycine, p-hydroxyphenylacetic acid, mandelic acid, acetophenone, α-thiophene glycolic acid, p-hydroxyphenylacetamide (tshuaj kho mob plawv thiab ntshav siab xws li atenolol). Tib lub sijhawm, nws siv los tsim cov tshuaj kho mob ulcer xws li capsule thiab allantoin.
Kev Ua Liaj Ua Teb:Cov kws tshawb fawb tau tsim cov yas uas yog los ntawm cov nroj tsuag los hloov cov yas ib txwm muaj. Cov yas tshiab no yog ua los ntawm cov tshuaj pheej yig, uas glyoxylic acid tuaj yeem muab cov suab thaj sib xyaw nrog cov pab pawg "nplaum" los ua lub hauv paus ntawm cov yas. Hauv kev ua liaj ua teb, cov yas tshiab no tuaj yeem siv rau ntau yam kev siv xws li kev ntim khoom, ntaub, tshuaj, thiab cov khoom siv hluav taws xob.
Kev tiv thaiv ib puag ncig:Lub voj voog glyoxylate yog qhov tseem ceeb heev hauv thaj chaw ntawm biochemistry. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tsis muaj lub teeb, cov nroj tsuag tuaj yeem hloov cov roj fatty acids mus rau hauv qab zib los ntawm lub voj voog glyoxylate kom tswj tau lub zog thiab cov pa roj carbon uas xav tau rau kev loj hlob, txhawb nqa lub voj voog khoom ntawm lub ecosystem, thiab txhim kho lub peev xwm los hloov kho rau cov chaw tsis zoo xws li kev qhuav thiab ntsev ntau.
Unilongyogib qho kev tshaj lij Glyoxylic acid CAS 298-12-4 chaw tsim khoom, peb tuaj yeem muab ntau yam khoom specifications ntawmTshuaj lom neeg organic, kev ruaj ntseg zoo, kev xa khoom sai, muaj nyob rau hauv Tshuag. Yog tias koj xav tau nws, thovtiv tauj peb.
