Ụlọ ọrụ mmepụta na ndị na-emepụta Oxalic Acid site na China Usoro Oxalic Oxidation

Usoro Oxidation Glyoxal nke Oxalic Acid
Glyoxal nwere ike ibelata ike ya, yabụ enwere ike ịgbaze ya ngwa ngwa ka ọ bụrụ oxalic acid n'okpuru ọrụ nke nitric acid siri ike na-eme ka ọ dị ọcha. N'ihi ihe ndị dị ka ọkọnọ ihe eji emepụta ihe, ọnụahịa, na teknụzụ, usoro a enweghị asọmpi ahịa na-adịghị mma ma emebeghị ka ọ bụrụ nke ụlọ ọrụ mmepụta ihe.
