The new MMA process of Dalian Institute of Chemistry, Chinese Academy of Sciences passed the identification

On July 27, the "nano-gold catalyzed methacrolein one-step oxidation esterification to MMA new process" passed the appraisal of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation, and the experts of the appraisal committee unanimously agreed that "the achievement is the first in China, generally reaching the international advanced level, agreed to pass the appraisal, and suggested to accelerate the construction and popularization of
the demonstration project.
" ”

The technology of "nano-gold catalyzed one-step oxidation of methacrolein to MMA" technology was developed by the research team of Huang Jiahui of the Dalian Institute of Chemistry of the Chinese Academy of Sciences for 6 years, and worked closely with Qingdao Sanli Bennuo New Materials Co.
, Ltd.
and the Department of Chemical Engineering of Tsinghua University to start the construction
of a 1,000-ton pilot plant in the Panjin Industrial Technology Research Institute of Dalian Institute of Chemicals in August 2019 。 In July this year, the technology passed the 72-hour full-load continuous and stable operation assessment organized by the China Petroleum and Chemical Industry Federation, and the results showed that the methacrolein conversion rate was 93.
2%, the MMA selectivity was 96.
9%, and the indicators reached the expected goals
