January 13th News On January 13th, Yangzhou Shiyou's 320,000-ton-per-year phenol-ketone plant operated normally, with prices raised by 150 to 4,450 yuan/ton. Shipments were primarily based on contractual plans, and inventory remained low. Chempricehub Analysis **Acetone** Bull-Bear Score: 1.5 Yangzhou Shiyou's acetone price increased by 150 yuan/ton to 4,450 yuan/ton. Low inventory and normal plant operations indicate tight supply in the spot market, with stable and improving demand, providing strong support for acetone spot prices. The positive factors are significant. **MIBK** Bull-Bear Score: 1 As acetone is the main raw material for MIBK, its price increase will raise MIBK production costs, indirectly exerting upward pressure on MIBK spot prices. However, the current market has not directly mentioned changes in MIBK supply and demand, so the impact is moderate.
