He aha te waikawa glyoxylic?

Ko te waikawa Glyoxylic, e mohiotia ana ko te waikawa formoic, te waikawa glyoxylic hydrated me te waikawa oxyacetic, te tauira matū C2H203, ko te waikawa aldehyde ngawari rawa, kei roto i nga hua karekau, nga rau matomato ngawari me nga pīti huka. Ko nga tioata mai i te wai he tioata monoclinic (kei roto 1/2 te wai tioata). He 70.04 te taumaha ngota ngota. Ko te ira whakarewa he 98 ℃. He reka kino. He waikawa haupapa kaha, he ngawari ki te whakaheke, ka taea te hanga i te whakapiri ina kitea ki te hau. He paku te wairewa i roto i te waiwaro, te etera me te benzene, ka taea te whakarewa noa ki te wai. He pūmau te wairewa wai, ā, karekau e kino ki te hau. Kei roto i te wairewa wai i te ahua o te wai. Ka taea te tauhohe me te nuinga o nga konganuku haunga te kowiri tira. Kei a ia nga ahuatanga o te waikawa me te aldehyde.
