Glyoxylic acid CAS 298-12-4
Glyoxylic acid CAS 298-12-4 , oo sidoo kale loo yaqaano formoic acid, hydrated glyoxylic acid iyo oxyacetic acid, caanaha kiimikada C2H203, waa aldehyde acid ugu fudud, kaas oo ku jira miraha aan qaan-gaarin, caleemaha cagaaran ee jilicsan iyo xididdada sonkorta. Kiristaalo ka yimaada biyaha waa kiristaalo monoclinic (oo ka kooban 1/2 biyo crystal ah). Miisaanka unugyadu waa 70.04. Barta dhalaalka waa 98 ℃. Waxay leedahay dhadhan aan fiicnayn. Waa asiidh daxalaysa oo xoog badan, taas oo ay fududahay in la damiyo oo waxay samayn kartaa koollo marka ay hawada gasho. Wax yar bay ku milmi kartaa ethanol, ether iyo benzene, waxayna si xor ah ugu milmi kartaa biyaha. Xalka aqueous waa xasiloon oo ma sii xumaanayso hawada. Waxay ku jirtaa xal aqueous qaab fuuq-bax. Waxa ay kaga falcelin kartaa biraha badankooda marka laga reebo birta aan daahin. Waxay leedahay sifooyinka acid iyo aldehyde.
