| Abstract: | The direct methyl esterification reaction for MMA was commercialized. Precisely synthesized Pd3Pb1 catalyst and the catalysis at the proposed reductive oxidation reaction condition (PROC) realized and guaranteed high MMA yield and long catalyst life. Controlled Pd distribution in a catalyst particle drastically decreased Pd loss from the catalyst during reaction. Unit processes are introduced as well. |
