Main Uses

Propionaldehyde is an important organic synthesis intermediate, and its uses are primarily based on the reactivity of the aldehyde group and the diversity of the resulting products:

Synthesis of n-propanol: n-propanol is produced through catalytic hydrogenation. It is an important solvent and chemical raw material used in coatings, inks, cosmetics, and other fields.

Synthesis of propionic acid: Propionic acid is prepared through oxidation. Propionic acid and its salts (such as sodium propionate) are food preservatives and are also used in feed additives, herbicides, etc.

Preparation of acetals: Acetals formed by condensation with alcohols can be used as solvents, fragrances, or organic synthesis intermediates.

Synthesis of other fine chemicals:

Used to prepare trimethylolpropane (an important polyol used in coatings, polyurethanes, resins, etc.); the reaction process involves the condensation of the aldehyde with formaldehyde followed by reduction;

Used as an intermediate for the synthesis of pharmaceuticals, fragrances, plastic additives, etc.
