Glyoxylic acid CAS 298-12-4
Glyoxylic acid CAS 298-12-4 , inozivikanwawo se formoic acid, hydrated glyoxylic acid uye oxyacetic acid, kemikari formula C2H203, ndiyo yakapfava aldehyde acid, inowanikwa mumichero isina kukura, nyoro mashizha egirini uye shuga beet. Makristasi anobva mumvura makristasi emonoclinic (ane 1/2 mvura yekristaro). Huremu hwema molecular huremu ndeye 70.04. Nzvimbo yekunyungudika i98 ℃. Iine kuravira kusingafadzi. Iorivhi ine corrosive acid yakasimba, iri nyore kuita deliquescence uye inogona kugadzira paste kana yaiswa mumhepo. Inonyungudika zvishoma mu ethanol, ether uye benzene, uye inogona kunyungudika zvakasununguka mumvura. Iyo aqueous solution yakagadzikana uye haiparadzi mumhepo. Inowanikwa mune aqueous solution nenzira ye hydration. Inogona kuita nesimbi zhinji kunze kwesimbi isina tsvina. Iine zvinhu zveasidhi uye aldehyde.
