Global demand for Acetic Acid (CAS 64-19-7) continues to fluctuate as downstream industries-including vinyl acetate monomer (VAM), PTA, solvents, and pharmaceuticals-respond to changes in crude oil prices, logistics costs, and regional production capacity.
In November 2025, the acetic acid market shows stable-to-firm pricing across most regions. China, as the world's largest producer, has seen moderate price recovery driven by plant maintenance and tightening supply. Meanwhile, South American importers continue to face high freight rates and currency fluctuations, pushing prices upward.
Market analysts forecast that Q4 2025 to Q1 2026 will maintain a steady upward trend, supported by stronger demand from coatings, adhesives, and acetate industries.

About Acetic Acid (CAS 64-19-7)
Acetic acid, also known as ethanoic acid, has the molecular formula C₂H₄O₂. It is a colorless, transparent liquid with a pungent odor. Under standard conditions, its melting point is 16.7°C, boiling point is 118°C, relative density at 20°C is 1.049, viscosity at 20°C is 1.22 mPa·s, and refractive index at 20°C is 1.3715. When anhydrous acetic acid solidifies at low temperatures, it forms an ice-like solid known as acetic acid ice, and its volume increases during the solidification process.
