“…In 2012, global acrylic acid production was 4.5 million metric tons, with a growing demand of 4% per year. [4][5][6] It is currently produced through a two-step gas-phase oxidation of propylene via acrolein. 4 This energy intensive process depends on petrobased propylene, the cost of which has been volatile recently.…”

“…As such, optimization of the reaction conditions is expected to surpass 90% selectivity. Combining these results with the pyrolysis of 2-APA at elevated temperatures, 6,26 we envisage 80-85% overall acrylic acid yield in the continuous ow reaction.…”

You will be contacted as soon as possible. We present an alternative synthetic route to acrylic acid, starting from the platform chemical lactic acid and using heterogeneous catalysis. To improve selectivity, we designed an indirect dehydration reaction that proceeds via acetoxylation of lactic acid to 2-acetoxypropionic acid. This intermediate can then be pyrolized to acrylic acid. Acetic acid is used both as a reagent and a solvent in the first step, and may be recovered in the subsequent pyrolysis step. We tested a range of solid acid catalysts for the acetoxylation step (Y zeolites, sulfated zirconia, ion-exchange resins, sulfonated graphene, and various sulfonated silica gels and mixed oxides). Recycling studies were carried out for the most active catalysts. To enable quantitative analysis using gas chromatography we also developed a reliable silylation derivatization method, which is also reported. These results open opportunities for improving the biorenewable production of acrylic acid.
