This week, the domestic market price of phthalic anhydride produced by o-phthalic acid was stable. As of the weekend, the price of phthalic anhydride produced by o-phthalic acid was 10300 yuan/ton, which was unchanged from the price of 10300 yuan/ton at the beginning of the week, with a year-on-year increase of 40.85%.

Supply side: maintenance of some phthalic anhydride devices in the site

Recently, the supply of goods in the phthalic anhydride plant is a little tight. Some domestic devices have been overhauled. The operating rate of 120000 ton phthalic anhydride plant in Tongling, Anhui is not high. The 100000 ton phthalic anhydride plant in Xinyang Group has been shut down. It is expected that the start-up and restart will be carried out after the National Day holiday. Affected by the overhaul of the devices, the domestic phthalic anhydride operating rate will remain below 50%. The domestic spot supply of phthalic anhydride is insufficient, and the price trend of phthalic anhydride on the site will remain high, The market price of phthalic anhydride in East China is 10200-10400 yuan/ton, and the market price of phthalic anhydride in North China is 10100-10300 yuan/ton.

Cost end: the price of raw ortho benzene remains high

The price of ortho benzene in China remained at a high level. As of the weekend, the price of ortho benzene was 9000 yuan/ton, and the price trend was temporarily stable this week. According to the manufacturer’s response, the supply of raw materials ortho benzene is tight in the near future, ortho benzene manufacturers are not enough to start construction, the factory has been shut down for maintenance, and phthalic anhydride manufacturers are hard to find supplies. The 160000 t/a ortho benzene unit of Zhenhai Refining and Chemical Co., Ltd. began to reduce the load gradually at the end of August, and the maintenance is expected to last for 3 months; Fuhaichuang 240000 t/a o-benzene plant has been shut down since the end of June; The 40000 t/a ortho benzene unit of Luoyang Petrochemical Company was shut down. In addition, the import of ortho benzene was not large, the main port inventory was not large, and the supply of ortho benzene was tight, which restricted the production of phthalic anhydride manufacturers. The price of ortho benzene remained high. Supported by favorable cost factors, the phthalic anhydride market remained high.

Demand side: plasticizer market can maintain DOP price

The downstream DOP market price of phthalic anhydride has not changed much. At present, the domestic DOP price is 10120 yuan/ton, down 0.49% from the beginning of the week’s 10170 yuan/ton. The domestic DOP enterprises started to work, and the demand for phthalic anhydride has increased. The mainstream DOP price is 10100-10300 yuan/ton. The DOP market trend remains, and the phthalic anhydride price is temporarily stable.

Looking at the future market: Recently, the port’s ortho xylene inventory is still in storage, domestic ortho xylene manufacturers have carried out more maintenance, the short-term supply of ortho xylene continues to be tight, the downstream plasticizer industry has improved, and the actual demand has increased compared with the previous. In addition, the supply of phthalic anhydride is tight, but the price of phthalic anhydride is at a high level, and the price increase of phthalic anhydride market is limited in the later period, mainly maintaining a high shock.
