Methylcyclopentadiene (MCPD) is a raw material for the production of rocket fuel RJ-4 and is also used in the production of various products, such as gasoline anti-knock agents, epoxy resin curing agents, pharmaceutical products, and dye additives. Currently, MCPD is mainly produced from by-products of petroleum cracking tar, with a low yield (about 0.7 kg/ton) and a high price (about 70,000 yuan/ton), which greatly limits its application. Therefore, exploring renewable biomass synthesis routes is of great significance.
Recently, the team of researcher Li Ning and academician Zhang Tao from the Dalian Institute of Chemical Physics successfully developed a new strategy for converting cellulose to MCPD, first converting cellulose to 3-methyl-2-cyclopentenone (MCP), and then selectively hydrogenating and deoxygenating it directly to produce MCPD over a zinc-molybdenum oxide catalyst.
The research results were published in Nature Communications.
Compared to the two-step process of selectively hydrogenating and then dehydrating MCP to produce MCPD reported by recent domestic and international scholars, the direct hydrogenation-deoxygenation technology has advantages such as a simpler process, fewer operational steps, and lower energy consumption.
