Dimethyl carbonate enterprises have far-reaching water
Dimethyl carbonate has been hailed as the 'new cornerstone of organic synthesis'. The China National Chemical Industry Council's National Carbonate Industry Alliance research team recently learned in the process of visiting the industry, the current production of DMC's important raw material propylene oxide market high fever , high prices are missing. Many DMC manufacturers are deeply helpless, and eagerly expect to have a sufficient and stable supply of raw materials.
The research team learned that most of the DMC enterprise devices currently operating in China use the transesterification process. One of the important raw materials is propylene oxide, which accounts for a large proportion of the cost. Therefore, the price of DMC is highly consistent with the price of propylene oxide. Benefiting from the booming downstream market such as DMC, the domestic propylene oxide price market has maintained a high degree of prosperity in recent years.
With the upgrading of environmental protection supervision, the propylene oxide enterprise using the production process of chlorohydrin is limited in operation, the market supply is tight, and the downstream demand is only increasing. The price of propylene oxide is extremely easy to rise rapidly in the short term. DMC production enterprises are under increasing pressure. At present, except for a few DMC companies that have their own propylene oxide equipment, the supply of propylene oxide in most companies in the industry is subject to people. The supply and demand pattern is already in the obvious seller market, and the stability of raw material prices is greatly reduced.
In response to this problem commonly reflected by DMC companies, the research team recently entered the domestic propylene oxide leading enterprise Shandong Binhua Group to conduct research visits. Xu Fengji, deputy general manager of Binhua Group, said that propylene oxide production enterprises are also facing certain Difficulties. He said that the chlorohydrin method of China's propylene oxide plant still dominates and is greatly affected by environmental protection policies. The shortcomings of the chlorohydrin process are more obvious in today's environmental protection background, and the industry is facing the pressure of transformation and upgrading. Energy-saving emission reduction, environmentally friendly high-quality product line is the main direction of future development. The indirect oxidation method has a huge production capacity. Only by solving the market sales of the co-production products can the advantages of indirect oxidation be highlighted. Direct oxidation method There are certain advantages in environmental protection and by-products, but further efforts are needed in terms of technical research and cost control.
On the other hand, the most important application of propylene oxide downstream is the polyether field, which accounts for about 80% of its total consumption, while the proportion used in the DMC industry is only 20%, so the impact of the DMC industry on the entire propylene oxide market. Smaller.
He believes that from the current situation, the propylene oxide market will continue to fluctuate, and DMC's raw material pressure will continue. When the propylene oxide new project capacity is released on a large scale, this problem will be solved.
Zhao Yongsheng, Marketing and Purchasing Manager of Binhua Group, told the research team that the current propylene oxide production capacity of Binhua Group is 250,000 tons/year, with 3 utility model patents and a number of proprietary technologies, and the market profitability is strong. In the future development of propylene oxide, Zhao Yongsheng said that they will further enlarge and strengthen the propylene oxide industry, adhere to scientific and technological innovation, green development concept, and the propylene oxide project using the new process route is under construction. .
