Recently, the hydrochloric acid Market in Hebei has declined in a narrow range. Industrial hydrochloric acid is widely used in the province, mainly distributed in chemical synthesis, pesticide, medicine, water treatment and other industries. The supply and demand remain moderate and the transaction volume is stable according to demand. Hydrochloric acid is mainly used for chlorine balance, and the market operation follows the market. The raw liquid chlorine continues to decline, and the cost of hydrochloric acid is not good enough. The amount of synthetic hydrochloric acid is stable on demand and the market turnover is stable. The by-product hydrochloric acid was promoted flexibly, and the factory shipment price was reduced by 30-50 yuan / ton.
