He aha ka glycoxylic acid?

ʻO ka waikawa Glyoxylic, ʻike ʻia hoʻi ʻo ka waika formoic, waika glyoxylic hydrated a me ka waika oxyacetic, ʻo ke kumu kemika C2H203, ʻo ia ka waikawa aldehyde maʻalahi loa, aia i loko o nā hua ʻai ʻole, nā lau ʻōmaʻomaʻo palupalu a me nā beets kō.ʻO nā kristal mai ka wai he mau kristal monoclinic (he 1/2 ka wai aniani).ʻO 70.04 ka paona molekala pili.ʻO ka helu heheʻe he 98 ℃.He ʻono maikaʻi ʻole kona.He ʻakika corrosive ikaika, he maʻalahi ke deliquescence a hiki ke hana i kahi paʻi ke ʻike ʻia i ka lewa.Hiki ke hoʻoheheʻe ʻia i loko o ka ethanol, ether a me benzene, a hiki ke hoʻoheheʻe ʻia i ka wai.He kūpaʻa ka wai a ʻaʻole e pōʻino i ka ea.Aia ia i loko o ka wai wai ma ke ʻano o ka hydration.Hiki iā ia ke hana me ka nui o nā metala koe wale ke kila kuhiliʻole.Loaʻa iā ia nā waiwai o ka waikawa a me ka aldehyde.
