Research Progress on Methyl Methacrylate Production Process
This article reviews various production processes and research progress of methyl methacrylate(MMA),including C4 method,C3 method,and C2 method,and compares the advantages and disadvantages of each process in producing MMA.The C4 method and C2 regulation avoid the drawbacks of the traditional C3 method(i.e.acetone cyanohydrin method),which uses highly toxic raw materials and generates a large amount of waste liquid.They have the advantages of safety and environmental protection in the production process and are the main development direction in the future.Among them,the C2 method's raw material ethylene is the most widely sourced and easily available,especially in the co production of coal to olefins,which can generate strong synergistic benefits,and has a development prospect in China,which is relatively rich in coal resources.
