Whakaahuatanga:
Ko te waikawa Glyoxylic, e mōhiotia ana ko te waikawa formic, te waikawa hydrated acetic, te waikawa oxoacetic rānei, me te tātai matū C2H203, ko te waikawa aldehyde māmā rawa atu e kitea ana i roto i ngā hua kāore anō kia pakari, ngā rau matomato ngawari, me ngā pīti huka. Ko te tioata mai i te wai he pūnaha tioata monoclinic (kei roto ko te 1/2 tioata wai). Ko te taumaha ngota whanaunga ko 70.04. Ko te ira rewa 98 ℃. He kakara kino, he waikawa tino waikura, he ngawari te memeha, ā, ka taea te hanga i te whakapiri ina pā ki te hau. He paku wairewa ki te etanoru, te etera, me te benzene, ka taea te memeha noa ki te wai, ā, he pumau te otinga wai, ā, kāore e pirau ki te hau. Kei roto i te āhua o te waikura i roto i te otinga wai. Haunga te maitai kore waikura, ka taea e ia te tauhohe ki te nuinga o ngā konganuku. He āhuatanga waikawa me te aldehyde ōna. Ka taea te tāpiri ki te konutai bisulfite, te waikawa hydrocyanic rānei, ka tauhohe ki te hydroxylamine, ki te phenylhydrazine rānei hei hanga oxime, hydrazone rānei, ka pā ki te tauhohenga whakaata hiriwa, ka pā ki te tauhohenga Conicoro, ā, ka taea hoki te whakaputa i ngā tote carboxylate me ngā esters.

Whakamahinga
Ka taea te whakamahi i te waikawa glyoxalic i roto i te hanganga o ngā momo tauhohenga.
Ka whakamahia te waikawa glyoxylic i roto i te tauhohenga Hopkins Cole, e whakamahia ana hei kimi i te tryptophan i roto i ngā pūmua.
Ka tauhohe ki te phenol ka puta ko te waikawa 4-hydroxymandelic, ā, i muri i te tauhohenga atu ki te haukini ka puta ko te hydroxyphenylglycine, hei matū mua mō te rongoā amoxicillin.
Ka whakamahia hoki hei rauemi tīmatanga mō te hanga i te waikawa 4-hydroxyphenylacetic, e whakamahia ana hei hanga atenolol.
Tākai
250KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
