The operation of domestic phthalic anhydride manufacturers has decreased, the operation rate of phthalic anhydride in the field has decreased slightly, the domestic supply of phthalic anhydride is tight, the price of upstream adjacent benzene is temporarily stable in August, and the downstream DOP price has increased. Affected by this, the price of phthalic anhydride has increased. The market price of phthalic anhydride in East China is rising, and the high-end transactions in the market are limited. The main negotiation price of adjacent method in East China is 8300-8400 yuan / ton, and the main negotiation price of naphthalene method is 8100-8200 yuan / ton; The mainstream price of the phthalic anhydride market in North China is 8300-8500 yuan / ton. The wait-and-see mentality of the phthalic anhydride market still exists, and the downstream purchase is mainly based on demand. In August, the price of phthalic anhydride rose.

In August, the price trend of domestic neighbor benzene was temporarily stable. The price in the market at the end of the month was 8000 yuan / ton, which was the same as the price at the beginning of the month.

Recently, the inventory of neighbor benzene in the port area was general, and the price of neighbor benzene in the external market was stable. The actual transaction price was subject to negotiation, and the actual order was discussed in detail, The low price of raw material o-benzene is unfavorable to the domestic market price of phthalic anhydride, and the increase of the market price of phthalic anhydride is limited.

In August, the downstream DOP market price of phthalic anhydride increased slightly. According to the monitoring of the business agency, the domestic DOP price by the end of the month was 9100 yuan / ton, with a price increase of 1.96%. The DOP raw material cost in the field was rising. The DOP enterprises started normally, the DOP supply was normal, and the downstream market trend was slightly higher.
