With the favorable development of the upstream and downstream of the industrial chain, the market demand for dimethyl phthalate (DMP) continues to release
Dimethyl phthalate, referred to as DMP, is an organic compound with the molecular formula C10H10O4. It appears as a colorless, transparent and slightly yellow oily liquid. It is insoluble in water and petroleum ether, and is miscible in general organic solvents such as ethanol and ether. The main preparation method of DMP is to use phthalic anhydride, methanol, ethanol, etc. as raw materials through esterification reaction.
Among them, phthalic anhydride is the material with the highest proportion of DMP raw material costs. In recent years, its production capacity has shown continued growth. In 2021, the total domestic production capacity of phthalic anhydride is 3.186 million tons, a year-on-year increase of 4.5%. The sufficient supply of upstream raw materials has laid a good foundation for the development of the domestic DMP industry.
DMP is one of the organic ester solvents. It has the characteristics of good molding properties, good waterproof performance, and strong adhesion. It is mainly used as a plasticizer in products such as cellulose acetate film, varnish, transparent paper, molding powder, and polyfluoride. Manufacturing of organic solvents such as vinyl coatings, methyl ethyl ketone peroxide, mosquito repellent oil, etc.
Specifically, in the field of cellulose acetate products, DMP, as one of its main plasticizers, can improve the durability and low-temperature softness of cellulose acetate plastic products. Acetate fiber is the second largest regenerated cellulose variety after viscose fiber. It has a wide range of applications and its output is currently showing a continuous increase. In 2021, domestic acetate fiber filament production has reached 566,000 tons, a year-on-year increase of 11.4%. As an important plasticizer in the field of acetate fiber production, DMP’s market demand continues to increase.
In the field of methyl ethyl ketone peroxide solvents, DMP is one of the effective solvents for its preparation, which can improve the stability of solvent performance. Methyl ethyl ketone peroxide, as a type of curing agent, is widely used in the fields of industrial anti-corrosion and FRP production. At present, the annual domestic production of FRP has exceeded 5 million tons, driving the increasing market demand for methyl ethyl ketone peroxide and its raw material DMP. Driven by the rapid development of downstream application fields, the domestic DMP market demand continues to increase. According to the“China Dimethyl Phthalate 2022-2026” released by the Industrial Research Center The “Research Report on Market Monitoring and Future Development Prospects of the DMP Industry” shows that the domestic market demand for dimethyl phthalate has reached 1.583 million tons in 2021.
Industrial Analysts personnel said that the domestic companies in the DMP market mainly include Jiarui Plastics, Aite New Materials, Jinshan Jingwei Chemical, Jifeng Plastic Additives, Xuejie Chemical, Yuanli Chemical Group, etc. At present, there are a large number of domestic DMP companies, but most of them are small and medium-sized enterprises. The industry concentration is low and the market competition is fierce. Currently, against the background of sufficient supply of phthalic anhydride raw materials in the upstream of the domestic DMP industry chain and the continuous expansion of the scale of cellulose acetate products and methyl ethyl ketone peroxide solvents in the downstream of the industry chain, its market demand continues to increase, and the industry shows great development prospects.
