Abstract:
The present invention relates to a method of synthesizing at least one organic acid comprising oxidizing glycolaldehyde with nitric acid in the presence of a solvent. Advantageously, it is an industrially applicable process, which prepares organic acid, notably glycolic acid and/or glyoxylic acid in a high yield based on bio-based feedstocks.
