March 10th News: On March 10th, Tongling Chemical Industry Group's phthalic anhydride production capacity is 80,000 tons. The ortho-xylene-based phthalic anhydride plant is operating normally, while the naphthalene-based phthalic anhydride equipment is undergoing maintenance, resulting in low inventory. The price of ortho-xylene-based phthalic anhydride is quoted at 11,000 yuan per ton, showing a significant increase. Chempricehub's analysis of phthalic anhydride indicates a bullish-bearish score of 2. The article highlights that the maintenance of Tongling Chemical Industry Group's naphthalene-based phthalic anhydride equipment has led to reduced supply. Although the ortho-xylene-based phthalic anhydride plant is operating normally, low inventory levels have driven a sharp price increase to 11,000 yuan per ton. This suggests tight market supply and strong demand, which is a significant positive factor for the spot price of phthalic anhydride. It is expected that spot prices will continue to rise in the short term.
