Synthesis of Tert-amyl Methyl Ether with Methanol and C5 Hydrocarbons

摘要

The reaction system and mechanism of etherification of C5 cut with methanol were analyzed theoretically.Experiments were carried out in a tubular reactor at temperatures of 50°C-80°C in the presence of a strong cation-exchange resin,QRE.In the reaction system,two types of reactions took place:etherification and isomerization.At lower temperature,the reaction rates were controlled by kinetic factors,but at temperature above 60°C,both reactions were affected by thermodynamic equilibrium.The appropriate operating conditions were:T at 60°C-65°C,molar ratio of methanol and isoamylenes 1.0-1.2,and liquid hourly space velocity (LHSV) 1.0-1.5.
