January 7th Update On January 7th, Yangzhou Shiyou's 320,000-ton-per-year phenol-acetone unit operated normally. The price was raised by 100 yuan to 4,300 yuan per ton, with contract shipments proceeding as planned and inventory remaining low. Chempricehub Analysis: **Acetone** – Bull-Bear Score: 1.5 Yangzhou Shiyou increased the acetone price by 100 yuan per ton to 4,300 yuan per ton, with low inventory and normal planned shipments, indicating tightening supply and strengthening market confidence. This is favorable for spot acetone prices and may prompt other producers to follow suit, reinforcing the short-term upward trend. **MIBK** – Bull-Bear Score: 0.5 Acetone is a key raw material for MIBK, and its price increase will raise MIBK production costs, potentially providing slight support for MIBK spot prices. However, downstream demand remains uncertain, limiting the overall impact. Further market developments should be monitored.
