PriceSeek analysis of acetone: Bullish-Bearish Score: 1 The article reports that the price of acetone has been raised by 50 yuan/ton to 4,900 yuan/ton. The unit is operating normally and shipments are proceeding as planned, indicating tight market supply or increased demand, which is favorable for spot prices. The price increase is relatively small (approximately 1%), representing a moderate positive. It is expected that spot prices may remain stable or rise slightly in the short term. MIBK: Bullish-Bearish Score: 0 The article does not mention any information related to MIBK, and there are no direct signals of supply-demand changes or price movements. Therefore, its impact on spot prices is neutral. As a downstream product of acetone, MIBK may be indirectly affected by fluctuations in raw material prices, but currently, there is insufficient specific data to support significant changes.
