Incazelo:
I-Glyoxylic acid, eyaziwa nangokuthi i-formic acid, i-hydrated acetic acid, noma i-oxoacetic acid, enefomula yamakhemikhali i-C2H203, iyi-aldehyde acid elula kakhulu etholakala ezithelweni ezingavuthiwe, amaqabunga aluhlaza athambile, kanye nama-beet kashukela. Ukwakheka kwamakristalu emanzini kuyisistimu yekristalu ye-monoclinic (equkethe amanzi ekristalu ayi-1/2). Isisindo sama-molecule esihlobene singama-70.04. Iphuzu lokuncibilika lingu-98 ℃. Inephunga elibi, iyi-acid ebolisa kakhulu, ilula kalula ukuncibilika, futhi ingakha ungqimba uma ivezwa emoyeni. Incibilika kancane ku-ethanol, i-ether, kanye ne-benzene, ingancibilika ngokukhululeka emanzini, kanti isixazululo samanzi sizinzile futhi asiboli emoyeni. Sikhona ngesimo sokuncibilika kusisombululo samanzi. Ngaphandle kwensimbi engagqwali, singasabela nezinsimbi eziningi. Sinezakhiwo ze-acidic kanye ne-aldehyde. Ingangezwa nge-sodium bisulfite noma i-hydrocyanic acid, isabela nge-hydroxylamine noma i-phenylhydrazine ukuze yakhe i-oxime noma i-hydrazone, ibhekane nokusabela kwesibuko sesiliva, ingabhekana nokusabela kwe-Conicoro, futhi ingakhiqiza nosawoti we-carboxylate nama-ester.

Ukusetshenziswa
I-Glyoxalic acid ingasetshenziswa ekwakhiweni kwezinhlobo ezahlukene zokusabela.
I-Glyoxylic acid isetshenziswa ekusabeleni kwe-Hopkins Cole, esetshenziswa ekutholeni i-tryptophan kumaphrotheni.
Isabela ne-phenol ukuze ithole i-4-hydroxymandelic acid, okuthi uma isabela ngokwengeziwe ne-ammonia inikeze i-hydroxyphenylglycine, njengesandulela sesidakamizwa i-amoxicillin.
Iphinde isetshenziswe njengento yokuqala yokulungiselela i-4-hydroxyphenylacetic acid, esetshenziselwa ukuthola i-atenolol.
Ukupakisha
250KG/Isigubhu noma ngokwezidingo zamakhasimende.
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
