After the holiday, the phthalic anhydride market fluctuated and fell
According to the Commodity Market Analysis System of Shengyi Society, as of October 11th, the price of phthalic anhydride in neighboring countries was 6216.67 yuan/ton, which fluctuated and fell by 1.22% compared to the price of phthalic anhydride at 6293.33 yuan/ton on October 1st. After the holiday, the price of ortho benzene fell, the price of industrial naphthalene fluctuated and fell, the cost support of phthalic anhydride decreased, and the equipment load of phthalic anhydride slightly decreased after the holiday in September. The operating rate of phthalic anhydride enterprises decreased, and the supply of phthalic anhydride was sufficient. The downstream plasticizer market fluctuated and fell, and the equipment operating load of plasticizer enterprises decreased. The demand support for phthalic anhydride weakened. Due to the decrease in costs and weakened demand support, the price of phthalic anhydride fluctuated and fell after the holiday.
After the holiday, the cost of phthalic anhydride decreased
On October 11th, Sinopec quoted 6300 yuan/ton for ortho benzene, a decrease of 100 yuan/ton or 1.56% from the price of 6400 yuan/ton on October 1st.

According to the Commodity Market Analysis System of Shengyi Society, lithium carbonate has shown a slight fluctuation trend recently. As of October 10th, the benchmark price of battery grade lithium carbonate in Shengyi Society was 73166 yuan/ton, a decrease of 1.26% month on month and 10.1% year-on-year; The benchmark price of industrial grade lithium carbonate trading company is 71366 yuan/ton, a decrease of 0.95% month on month and 9.13% year-on-year.
Supply side: Reduced disturbance at the mining end
In July, there was a notice from the Natural Resources Bureau of Yichun City, Jiangxi Province in the industry. The notice requires eight local lithium mining enterprises to complete the preparation of a verification report on the change of mineral types and reserves before September 30th, and scientifically and reasonably determine the main mineral types for mining. Affected by this news, the spot price of lithium carbonate soared from 60000 to 80000, but the market cooled down rationally and returned to around 70000. Recently, it has been reported that all eight lithium mining companies have submitted their verification reports for changes in mineral types and reserves. The impact of mining on supply has weakened.
Demand side: Energy storage dominates incremental growth, highlighting demand resilience
Energy storage has become the core engine of demand in October, and the delivery cycle of orders from top energy storage battery companies (such as CATL and BYD) has been extended to 45 days. The production rate in September remains above 95%, and the output of positive electrode material factories is expected to continue the month on month upward trend.
The demand for power batteries is steadily improving
The sales volume of new energy passenger vehicles in the market was 1.123 million units, a year-on-year increase of 50.9%, with a penetration rate of 53.3%. Although the reduction of subsidies in Europe and the United States has slowed down the growth rate of export orders, the demand in the domestic market during peak seasons has supported a steady increase in the installed capacity of power batteries, and demand resilience still exists.
Inventory is still at a high level
As of the end of September, the total inventory of lithium carbonate was 136800 tons, including 33500 tons of upstream inventory, 60900 tons of downstream inventory, and 42400 tons of inventory in other links. The suppressive effect of high inventory on prices has not completely subsided, and the supply and demand increment in October may turn into accumulated inventory, restricting the upward space of prices.
The lithium carbonate data analyst from Shengyi Society believes that the lithium carbonate market in October will be in a balanced state of “improvement in supply and demand margins” and “suppression of high inventory”, and prices may fluctuate slightly. Specific changes in the market still need to be monitored.

During the holiday period, the shipment performance of n-butanol was average, and the overall market situation has been adjusted downwards. On the first day after the holiday, the focus of the n-butanol market in Shandong continued to move downwards. As of October 9th, the reference price for n-butanol market in Shandong region is around 5650-5700 yuan/ton.
Analysis of Market Factors
Supply side: Increased supply and pressure on shipments
During the National Day holiday, the shipment of n-butanol in Shandong slowed down, and the overall supply in the market increased, but the support provided by the supply side to the market was not satisfactory. After the supply was under pressure, the overall market in Shandong was mainly focused on selling at a discounted price after the holiday, and the focus of market trading was adjusted downwards.
In terms of demand, the transmission of essential procurement is generally average
After the holiday, the downstream demand for n-butanol is generally average, with a focus on first-time purchases. Downstream users mainly digest raw materials from earlier stages, and the support provided by the demand side to the market is limited.
Future forecast
At present, the inquiry atmosphere in the n-butanol market is relatively light, and the mentality of industry players is average. The transmission of supply and demand is relatively slow. The n-butanol data analyst from Shengyi Society predicts that in the short term, the domestic n-butanol market will mainly experience narrow adjustments, and specific changes in supply and demand news need to be closely monitored.

The domestic epoxy propane market fluctuated upward in September. According to the monitoring system of Shengyi Society, as of September 30th, the benchmark price of Shengyi Society’s epoxy propane was 7766.67 yuan/ton, an increase of 4.25% compared to September 1st.
Price influencing factors:
Raw material side: In September, the price of propylene fluctuated and provided limited support for the cost of epoxy propane, but did not exert significant pressure on the cost of epoxy propane. According to the market analysis system of Shengyi Society, as of September 30th, the benchmark price of propylene in Shengyi Society was 6598.25 yuan/ton, a decrease of 0.98% compared to the beginning of this month (6663.25 yuan/ton).
Supply side: In the mid to early period, the market was boosted by the news of Shandong’s release of equipment parking, and the trading atmosphere in the market warmed up; In the later stage, the load reduction of the first phase unit in Shandong and the temporary shutdown of the Dongying unit resulted in tight spot inventory of domestic epoxy propane production enterprises. The supporting role of the supply side in the market has been strengthened, and the price of epoxy propane continues to rise.
On the demand side: In mid September, downstream demand for replenishing inventory was concentrated, and the new transaction volume of polyether factories increased significantly, which significantly increased the enthusiasm for purchasing epoxy propane. It is expected that the price trend of epoxy propane will be strong in the later stage.
Market forecast:
Business Society’s epoxy propane analyst believes that the supply of epoxy propane in the market is tight, with limited support from raw material prices, and downstream market demand is still acceptable. It is expected that the focus of the epoxy propane market will shift upwards in the later stage, and more attention should be paid to changes in raw material prices and downstream supply and demand.
