⁣Introduction to Acetaldehyde Acid

Glyoxylic acid, also known as formic acid, hydrated acetic acid, or oxoacetic acid, with the chemical formula C2H203, is the simplest aldehyde acid found in immature fruits, tender green leaves, and sugar beets.

Crystallization from water is a monoclinic crystal system (containing 1/2 crystal water). The relative molecular weight is 70.04. Melting point 98 ℃. It has an unpleasant odor, is a highly corrosive acid, easily deliquescent, and can form a paste when exposed to air. Slightly soluble in ethanol, ether, and benzene, can dissolve freely in water, and the aqueous solution is stable and does not deteriorate in air.

Acetic acid is an important raw material for fine chemicals, widely used in pharmaceuticals (mainly for broad-spectrum antibiotics such as amoxicillin, antihypertensive drug atenolol, cosmetic additives such as allantoin, high value-added aromatic aldehydes, p-hydroxybenzoic acid, etc.), water stabilizers, fragrances (ethylvanillin), pesticide intermediates, etc
