Gịnị bụ glyoxylic acid CAS 298-12-4?

Glyoxylic acid CAS nọmba 298-12-4, nke a makwaara dị ka formoic acid, hydrated glyoxylic acid na oxyacetic acid, usoro kemịkalụ C2H203, bụ aldehyde acid kachasị mfe, nke dị na mkpụrụ osisi na-etobeghị eto, akwụkwọ ndụ akwụkwọ ndụ dị nro na beets shuga. Kristal sitere na mmiri bụ kristal monoclinic (nwere 1/2 mmiri kristal). Ibu molekul dị n'ime ya bụ 70.04. Ebe agbaze bụ 98 ℃. Glyoxylic acid nwere uto na-adịghị mma. Glyoxylic acid bụ acid siri ike nke na-emebi emebi, nke dị mfe ịtọ ụtọ ma nwee ike ịmepụta mado mgbe a na-ekpughe ya na ikuku. Glyoxylic acid na-agbaze ntakịrị na ethanol, ether na benzene, enwere ike ịgbaze ya n'ime mmiri. Mmiri mmiri ahụ kwụsiri ike ma ọ naghị emebi n'ikuku. Mmiri Glyoxylic acid dị na mmiri mmiri n'ụdị mmiri mmiri. Glyoxylic acid nwere ike imeghachi omume na ọtụtụ ọla ma e wezụga ígwè anaghị agba nchara. Mmiri Glyoxylic acid nwere ihe onwunwe nke acid na aldehyde.

Glyoxylic acid (CAS 298-12-4) enweghị ọkọlọtọ ịdị ọcha a kapịrị ọnụ ma dị n'otu. A ghaghị kewaa ịdị ọcha ya dịka ụdị akọwapụtara (mmiri kristal ma ọ bụ mmiri) na ọnọdụ ojiji ya si dị. Anyị nwere ike inye nkọwapụta abụọ bụ isi:glycoxylic acid nkeji 98%(kristal) naglycolic acid 50%(mgwọ mmiri).
