Synthetic glyoxylic acid:

The detailed steps for synthesizing glyoxylate by oxalic acid electrolysis are as follows:

(1) Oxalic acid electrolysis: Oxalic acid is added to an electrolytic cell and decomposed into hydrogen gas and carbon dioxide gas through the electrolysis process. The chemical equation for this step is: H₂C₂O₄ → H₂ + CO₂.

(2) Gas separation: Separate the hydrogen gas and carbon dioxide gas produced by electrolysis and collect pure hydrogen gas. This step can be achieved through gas separation devices, typically using molecular sieve adsorption or low-temperature liquefaction methods.

(3) Hydrogen reduction: The collected pure hydrogen gas is introduced into the reactor, mixed with oxygen in the air, and undergoes a reduction reaction under the action of a catalyst to generate acetaldehyde. The chemical equation for this step is: 2H₂ + O₂ → 2H₂O.

(4) Acetaldehyde oxidation: The generated acetaldehyde is introduced into an oxidizing agent (such as air or oxygen) and undergoes an oxidation reaction under the action of a catalyst to produce glyoxylate. The chemical equation for this step is: 2CH₃CHO + O₂ → 2CH₃COOH.

(5) Product separation and purification: Separate the generated glyoxylate from the reaction solution and purify it. This step usually involves methods such as distillation and extraction.

In addition to oxalic acid electrolysis, there are other methods for synthesizing glyoxylate, such as chemical oxidation and biological fermentation. Different methods have different advantages and disadvantages, and suitable methods can be selected according to actual needs. Among them, the chemical oxidation method usually uses formaldehyde or acetylene as raw materials to generate glyoxylate through oxidation reactions. The biological fermentation method utilizes microbial fermentation to produce acetaldehyde.

Overall, oxalic acid electrolysis is a commonly used method for synthesizing glyoxylate, with high yield and purity. However, this method requires a large amount of electricity and raw materials consumption, as well as generating certain amounts of wastewater and exhaust gas. Therefore, corresponding environmental protection measures and energy-saving technologies need to be taken to reduce production costs and environmental pollution.

The oxalic acid electrolysis method for synthesizing glyoxylate is an important organic chemical production method with broad application prospects and value. To ensure its sustainable development and efficiency, it is necessary to strengthen technological research and innovation, while taking corresponding environmental protection measures and energy-saving technologies to reduce production costs and environmental pollution.

The detailed steps for synthesizing Glyoxylic Acid Solution by glyoxal oxidation method are as follows:

1. Preparation of glyoxal: Add formaldehyde solution to a reaction vessel and undergo condensation reaction under the action of an acidic catalyst to generate glyoxal. The chemical equation for this step is: 2HCHO → H₂C₂O₂.

2. Oxidation of glyoxal: The glyoxal is introduced into a reactor containing a catalyst and undergoes an oxidation reaction with air or oxygen to produce glyoxal acid. The chemical equation for this step is: H₂C₂O₂ + O₂ → H₂C₂O₂ · H₂O.

3. Product separation and purification: Separate the generated glyoxylate from the reaction solution and purify it. This step usually involves methods such as distillation and extraction.
