Chempricehub Analysis: - **Acetone**: Bullish-Bearish Score: 2 Gaoqiao Petrochemical's acetone quotation increased by 100 yuan per ton to 4,300 yuan per ton. The shutdown of its 240,000-ton-per-year phenol-acetone unit has reduced supply, significantly benefiting spot prices. Short-term prices are expected to rise notably. - **MIBK**: Bullish-Bearish Score: 1 As a downstream product of acetone, the tight supply and rising prices of acetone may increase MIBK production costs, supporting its spot prices and constituting a moderate positive impact. However, the extent of this effect depends on downstream demand transmission.
