How does the acetone supply chain support MMA production in China, and what quality specs matter most?
Acetone is the primary raw material for MMA via the acetone cyanohydrin (ACH) route, which dominates China's MMA capacity. For MMA producers, acetone quality directly impacts yield: purity must meet national premium grade of at least 99.5%, with low water and aldehyde content to avoid consuming hydrogen cyanide or triggering side reactions. East China, especially Shanghai, is the core phenol-acetone cluster, with plants from Sinopec, Zhejiang Petrochemical, and Lihuayi providing stable supply. Proximity to these upstream plants reduces logistics costs and ensures batch consistency, which is critical for continuous MMA operations. Buyers should prioritize direct-from-plant sourcing with COA documentation and tanker delivery to maintain quality and supply security.
