In October, the domestic market price of phthalic anhydride by phthalic acid method continued to rise,Up to now, the quotation of phthalic anhydride by o-phthalic method is 10500 yuan/ton, rising 1.94% in the three days after the festival, mainly due to the tight supply and cost support. The phthalic anhydride market continues to rise, and the price of phthalic anhydride reaches an eight year high .

Supply side: the spot supply of phthalic anhydride plant maintenance is tight

Recently, the supply of phthalic anhydride on the site is very tight. Some domestic devices have been overhauled. The 120000 ton phthalic anhydride device in Tongling, Anhui Province has been overhauled and no goods have been sold. The 100000 ton phthalic anhydride device of Xinyang Group has not been started. Affected by the overhaul device, the domestic phthalic anhydride operating rate has remained below 50%. The domestic spot supply of phthalic anhydride is very tight. The price of phthalic anhydride on the site continues to rise, reaching an eight year high, The market price of phthalic anhydride in East China is 10500-10600 yuan/ton, and the market price of phthalic anhydride in North China is 10400-10500 yuan/ton.

Cost end: the price of ortho benzene rises sharply

The price of domestic ortho benzene rose sharply. As of October 10, the price of ortho benzene was 9600 yuan/ton, up 6.67% in October. 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 phthalic acid plant of Luoyang Petrochemical stopped production. In addition, the import volume of phthalic acid is not large, and the inventory of main ports has dropped to 8000 tons. The supply of phthalic acid is tight, which restricts the production of phthalic anhydride manufacturers. In addition, the price of phthalic acid has risen significantly. Supported by the cost positive factors, the phthalic anhydride market continues to rise.

Demand side: the higher DOP market demand is guaranteed

The downstream DOP market price trend of phthalic anhydride is rising. At present, the domestic DOP price is 10440 yuan/ton. The domestic DOP enterprises have started to work steadily, and the demand for phthalic anhydride is guaranteed. The mainstream DOP price is 10400-10600 yuan/ton. The rising downstream market is a good support for the phthalic anhydride market, and the phthalic anhydride price continues to rise.

In the future, the port’s ortho xylene inventory is low in the near future, the domestic ortho xylene manufacturers have carried out more maintenance, and the short-term supply of ortho xylene continues to be tight. In addition, the downstream plasticizer industry has gradually entered the peak sales season, and the actual demand has increased compared with the previous one. In addition, the supply of phthalic anhydride is tight, so there are still positive factors, and the market price of phthalic anhydride may rise slightly in the later period.
