KAYAMBIDWE:
Kufotokozera:
Glyoxylic acid, yomwe imadziwikanso kuti formic acid, hydrated acetic acid, kapena oxoacetic acid, yokhala ndi formula ya mankhwala C2H203, ndiye aldehyde acid yosavuta kwambiri yomwe imapezeka mu zipatso zosakhwima, masamba obiriwira ofewa, ndi beets a shuga. Kupangidwa kwa kristalo kuchokera m'madzi ndi njira ya kristalo ya monoclinic (yomwe ili ndi 1/2 madzi a kristalo). Kulemera kwa molekyulu ndi 70.04. Malo osungunuka ndi 98 ℃. Ili ndi fungo losasangalatsa, ndi asidi wowononga kwambiri, wosavuta kusungunuka, ndipo imatha kupanga phala ikayikidwa mumlengalenga. Yosungunuka pang'ono mu ethanol, ether, ndi benzene, imatha kusungunuka momasuka m'madzi, ndipo yankho lamadzi limakhala lokhazikika ndipo siliwonongeka mumlengalenga. Lilipo mu mawonekedwe a hydration mu yankho lamadzi. Kupatula chitsulo chosapanga dzimbiri, imatha kuchitapo kanthu ndi zitsulo zambiri. Ili ndi mphamvu ya acidic ndi aldehyde. Ikhoza kuwonjezeredwa ndi sodium bisulfite kapena hydrocyanic acid, kuchitapo kanthu ndi hydroxylamine kapena phenylhydrazine kuti ipange oxime kapena hydrazone, kuchitapo kanthu ngati silver mirror reaction, kuchitapo kanthu ngati Conicoro reaction, komanso kupanga carboxylate salts ndi esters.

Kagwiritsidwe Ntchito
Glyoxalic acid ingagwiritsidwe ntchito popanga zinthu zosiyanasiyana.
Glyoxylic acid imagwiritsidwa ntchito mu Hopkins Cole reaction, yomwe imagwiritsidwa ntchito pozindikira tryptophan mu mapuloteni.
Imakumana ndi phenol kuti ipange 4-hydroxymandelic acid, yomwe ikakumananso ndi ammonia imapereka hydroxyphenylglycine, ngati choyambira cha mankhwala a amoxicillin.
Amagwiritsidwanso ntchito ngati chinthu choyambira pokonzekera 4-hydroxyphenylacetic acid, yomwe imagwiritsidwa ntchito popanga atenolol.
Kulongedza
250KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
