Basic Info

Production method

Formaldehyde and propionaldehyde are usually used as raw materials. Under the action of catalysts such as potassium carbonate, condensation reaction is used to generate 2,2-dihydroxymethyl propionaldehyde, and then the aldehyde group is oxidized to a carboxyl group through an oxidation reaction to obtain 2,2-dihydroxymethyl propionic acid.

Uses

Chemical industry: 2,2-Bis(hydroxymethyl)propionic Acid is a chemical monomer material for synthesizing polyester, polyurethane and other compounds, and is used in the production of coatings, adhesives, and inks.
Electronics: Used in the production of photoresists, photosensitive materials, etc.
Plastics: As a plastic additive, it enhances the strength and toughness of plastics and slows down the aging of plastics.
Pharmaceuticals: As a drug excipient, it improves the solubility and biodegradability of drugs.
Adhesives: As an additive, it improves the strength and water resistance of adhesives.
