Glyoxylic acid and acetic acid are common chemical substances, they have a wide range of applications in chemical, pharmaceutical and other fields. However, many people are not clear about the difference between these two substances. The following will introduce the chemical structure, properties and uses to help readers better understand the difference between glyoxylic acid and acetic acid.

1. chemical structure
glyoxylic acid chemical formula is C2H4O3, it is a carboxylic acid, that is, there is a carboxyl group (-COOH) of organic matter. The chemical formula of acetic acid is C2H4O2, which is an ester compound, which is prepared by esterification of ethanol and acetic anhydride. From the chemical structure, glyoxylic acid and acetic acid, although both contain ethyl groups, but their functional groups are different, respectively, carboxyl and carboxylate groups.

2. properties
glyoxylic acid is a solid, white crystal at room temperature, with strong corrosive and pungent odor. Acetic acid is a colorless transparent liquid, vinegar flavor. In nature, glyoxylic acid is more active and easily reacts with other substances, while acetic acid is relatively stable.

3. uses
because glyoxylic acid has a strong corrosive, more for industrial deoxidation and anti-corrosion treatment. Acetic acid is commonly used in the production of cellulose acetate and in food processing. In addition, glyoxylic acid is an important organic synthesis intermediate, is widely used in medicine, dyes, spices and other industries. As an acidic substance, acetic acid can be used in food, medicine, cosmetics and other fields.

To sum up, glyoxylic acid and acetic acid have obvious differences in chemical structure, properties and uses. In practical applications, it is necessary to select appropriate chemical substances according to specific conditions to ensure product quality and production safety.
