Chempricehub Analysis: Acetone, Bullish/Bearish Score: 2 Reason: Sinopec East China raised its acetone listed price by 200 yuan/ton to 4,850 yuan/ton, indicating proactive price increases by suppliers and reflecting tight market supply or strong demand. This constitutes a significant positive impact on acetone spot prices, with expectations of a notable short-term increase. MIBK, Bullish/Bearish Score: 1 Reason: Acetone is the primary raw material for MIBK production. The rise in acetone prices will increase MIBK production costs, potentially driving up MIBK spot prices, which constitutes a generally positive impact. However, attention should be paid to changes in downstream demand to confirm sustainability.
