Propionaldehyde

　　Main Uses

　　Propionaldehyde is an important intermediate in organic synthesis, 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 intermediates in organic synthesis.

　　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.
