In November, the DOP market in China contracted. On November 8, the price of DOP was 12,175.00 RMB/MT, down 0.41 percent from the price of 12,225.00 RMB/MT on November 5, indicating the downward pricing of DOP. The cost of the raw materials 2-EH and PA decreased, lowering the total cost of DOP. The price of downstream plastic PVC plummeted precipitously, and demand decreased. While the number of DOP makers climbed slowly at first, the supply of DOP increased, easing the shortfall.

Production Process

  • Production of DOP via Esterification
