According to statistics, the domestic phthalic anhydride price will rise as a whole in 2021. The price at the beginning of the year will be 7175 yuan/ton, and that on December 12 will be 8050 yuan/ton. In 2022, the phthalic anhydride price will rise significantly by 12.20%. The highest price in the year will appear on October 16, the highest price will be 10,637.5 yuan/ton, and the lowest price in the year will appear on January 1, the lowest price will be 7175 yuan/ton, and the maximum amplitude in the year will be 48.26%.

It can be seen from the domestic phthalic anhydride price trend chart in recent five years that the phthalic anhydride price will be at a high level in 2022, and the high market price of phthalic anhydride will generally appear in the fourth quarter. The price trend of phthalic anhydride market will decline in the second quarter, and the market price of phthalic anhydride will rise in 2022. It can be seen from the trend chart that the price trend of phthalic anhydride can be roughly divided into four stages. The first stage is from the beginning of the year to the middle of March, when the price of phthalic anhydride rises; The second stage is the period from late March to the end of July, during which the phthalic anhydride market fluctuated and fell; The third stage is from the beginning of August to the middle of October, during which the price of phthalic anhydride rises rapidly; In the fourth stage, the market price of phthalic anhydride fell sharply from late October to December 12.

In the first stage, from the beginning of the year to the middle of March, the domestic phthalic anhydride market price rose. The price at the beginning of the year rose from 7175 yuan/ton to 9150 yuan/ton in the middle of March, up 27.53%. The domestic phthalic anhydride market rose significantly. First of all, the domestic phthalic anhydride manufacturers maintained a low level of commencement. The on-site phthalic anhydride operation rate was more than 50%. The domestic spot supply of phthalic anhydride was slightly tight. The price of phthalic anhydride on the market rose, and the downstream plasticizer industry rose significantly. The actual transaction was obviously favorable, and the phthalic anhydride market rose. Secondly, the price of ortho benzene as upstream raw material has risen sharply. The domestic market price of ortho benzene has risen from 6300 yuan/ton to 9000 yuan/ton, an increase of 42.86%. In addition, the import price of ortho benzene in the port area has risen sharply, and the quotation of ortho benzene in the external market has risen. The sharp rise in the price of ortho benzene as upstream raw material has formed cost support for the phthalic anhydride market, and the market price of phthalic anhydride has risen significantly.

The second stage is the period from late March to the end of July, during which the phthalic anhydride market fluctuates. The price in late March was 9150 yuan/ton, down to 7950 yuan/ton at the end of July, a decline of 13.11%. Recently, the price trend of phthalic anhydride market has declined, and the purchase situation of phthalic anhydride market is general. Recently, downstream demand has decreased, the price trend of ortho benzene has dropped significantly, and the plasticizer market has declined. The superposition of negative factors has led to the continuous decline of phthalic anhydride market price. The domestic phthalic anhydride manufacturers started up slightly, and the on-site phthalic anhydride operating rate rose to about 60%. The domestic spot supply of phthalic anhydride was sufficient, and the on-site wait-and-see attitude of phthalic anhydride remained. Downstream procurement was poor. Recently, the downstream DOP market trend fell back, which affected the price trend of phthalic anhydride market.

The third stage is from the beginning of August to the middle of October, during which the price of phthalic anhydride rises rapidly. The market price of phthalic anhydride increased by 33.81% from 7950 yuan/ton in early August to 10637.5 yuan/ton in the middle of October. At this stage, the domestic market price of phthalic anhydride continued to rise. At this stage, the domestic supply of phthalic anhydride was tight, some units were unstable, and the supply of goods was limited to a certain extent, The order scheduling situation occurred, and the serious contradiction between supply and demand led to the continuous rise of domestic phthalic anhydride market price. In addition, the supply of phthalic anhydride raw materials is tight recently, phthalic anhydride manufacturers have difficulty in purchasing, they are not enthusiastic enough to start work, the factory has stopped production for more maintenance, and the supply of ortho benzene is tight, resulting in a shortage of raw materials for phthalic anhydride manufacturers, which restricts their production. In addition, the price of phthalic anhydride has risen sharply, supported by favorable factors, and the price of ortho benzene has risen. The downstream DOP market price rose significantly, and the downstream demand was favorable. At this stage, the DOP price rose 14.51%. The customers actively purchased, and the multiple advantages overlapped, so the market price of phthalic anhydride rose significantly.

In the fourth stage, the market price of phthalic anhydride fell sharply from late October to December 12. The price of phthalic anhydride dropped from 10637.5 yuan/ton to 8050 yuan/ton at the end of the year, a decline of 24.32%. The market price of phthalic anhydride dropped sharply, and the shipment of phthalic anhydride on the site was not good. Recently, the supply of phthalic anhydride increased, some domestic maintenance devices restarted, and Anhui Tongling phthalic anhydride began to ship normally. The 100000 ton phthalic anhydride device of Xinyang Group operated stably. Affected by the restart of the device, the domestic phthalic anhydride operating rate rose to about 60%, and the domestic phthalic anhydride capacity was severely overcapacity, The supply of phthalic anhydride is sufficient, and the market price drops. At this stage, the downstream plasticizer industry was weak, and the actual transaction was not good. The situation of ortho benzene in the upstream has declined. In addition, the plasticizer industry is in a downturn and the demand is sluggish. The market price of phthalic anhydride has fallen sharply.

To sum up, the domestic phthalic anhydride market will rise in 2022. The price trend of ortho phthalic anhydride is similar to the market price of phthalic anhydride. The downstream plasticizer industry is the direct factor affecting the price of phthalic anhydride. Nefa phthalic anhydride has a great impact on ortho phthalic anhydride, and the market price of phthalic anhydride will also be affected to some extent.

Future forecast: the domestic phthalic anhydride market has a serious overcapacity. In addition, the naphthalene phthalic anhydride continues to increase its capacity, and the neighboring phthalic anhydride is somewhat suppressed. In addition, the real estate market in the past two years is not optimistic, the plasticizer industry has been affected to some extent, and the demand has not increased significantly. In addition, the naphthalene phthalic anhydride continues to impact the market. It is estimated that the highest price of phthalic anhydride in 2023 may still be in the fourth quarter, and the highest price is about 9500 yuan/ton, The lowest price may appear in the second quarter, which is about 6000 yuan/ton.
