Annual output of 10,000 tons of the Methyl methacrylate
production process design
Abstract
Methyl methacrylate (MMA) because of their excellent performance and a wide range of uses， has become a great market potential of chemical products. This pape describes the main methyl methacrylate (MMA) and development of major progress in production technology and technical and economic analysis of various processes and described the MMA production capacity at home and abroad and demand situation. Analysis of domestic and international market demand for methyl methacrylate and trends，presented the proposed country of methyl methacrylate，expansion projects，industrial development is proposed should be paid attention to avoid a few problems. This article also discusses the methyl ester of methacrylic acid nature of the product，use，market analysis，supply and demand，consumer trends and the results of the analysis，gives some suggestions. Industrial development is proposedshould be paid attention to avoid a few problems.
