Unilong tuaj yeem muab glyoxylic acid 50% kua thiab 99% hmoov CAS 298-12-4
Glyoxylic acid, tseem hu ua formoic acid, hydrated glyoxylic acid thiab oxyacetic acid, tshuaj formula C2H203, yog qhov yooj yim aldehyde acid, uas muaj nyob rau hauv cov txiv hmab txiv ntoo tsis paub qab hau, kev sib tw ntsuab nplooj thiab qab zib beets. Crystals los ntawm dej yog monoclinic crystals (muaj 1/2 siv lead ua dej). Tus txheeb ze molecular hnyav yog 70.04. Lub melting point yog 98 ℃. Nws muaj ib qho tsis kaj siab saj. Nws yog ib qho muaj zog corrosive acid, uas yog ib qho yooj yim rau deliquescence thiab tuaj yeem tsim ib qho muab tshuaj txhuam thaum raug huab cua. Nws yog me ntsis soluble hauv ethanol, ether thiab benzene, thiab tuaj yeem yooj yim soluble hauv dej. Cov tshuaj aqueous yog ruaj khov thiab tsis deteriorate hauv huab cua. Nws muaj nyob rau hauv aqueous tov nyob rau hauv daim ntawv ntawm hydration. Nws tuaj yeem cuam tshuam nrog cov hlau feem ntau tsuas yog cov hlau tsis muaj steel. Nws muaj cov yam ntxwv ntawm acid thiab aldehyde.
