Description
Crotonic Acid Product Overview
Crotonic acid (C4H6O2), or trans-2-butenoic acid, is a white crystalline solid that melts at about 70–72°C. It dissolves in water and most organic solvents and has a pungent odor. Its double bond and carboxylic acid group make it a useful building block.
The main application is copolymerization with vinyl acetate. Even small amounts introduce carboxyl groups into the polymer, which makes it soluble in alkaline water. Polymer producers use these copolymers in hair styling resins, paper coatings, textile sizes and removable adhesives. Related vinyl-based polymers include Polyvinyl Alcohol.
In fine chemical synthesis, it serves as a starting material for crotonate esters, pharmaceutical and agrochemical intermediates, and specialty resins. For simpler carboxylic acids used in similar processes, see Acetic acid and Formic Acid.
