Technology Status and Market Analysis of Methyl Methacrylate Based on Patent
[Purposes]Methyl methacrylate(MMA)is an important organic chemical raw material and polymer monomer.Based on the perspective of patents,this paper analyzes MMA-related technologies and the current situation of the MMA market,so as to provide suggestions and references for the develop-ment of China's MMA industry.[Methods]This paper summarizes the synthesis technology of methyl methacrylate at home and abroad;by searching and analyzing the Chinese patent application literature of MMA,the statistical analysis is conducted from dimensions such as patent application trends,source country composition,main applicants,and IPC classification;the current situation of MMA market is ana-lyzed from the aspects of production capacity,price,consumption and import and export volume.[Find-ings]MMA-related technologies and industrialization are relatively mature,and related patented tech-nologies concentrated in synthesis technology,devices,catalysts,and process flow.The design produc-tion capacity of MMA in China has exceeded 2 million tons,and product prices have been increasing steadily.[Conclusions]At present,nearly 75%of MMA production capacity in China is still achieved through the ACH method,and the development of high-efficient isobutene oxidation catalysts will pro-mote the isobutene oxidation to become the main production technology route in the future.
