In recent years, a new route to acrylic acid (acrylate) production through the condensation
Abstract:
reaction between formaldehyde and acetic acid (methyl acetate) received substantial attention from both
academic and industrial communities. This reaction route is technically simpler and the feedstock can be
obtained from natural gas and coal, which is economically favorable for sustainable acrylic acid
production. So far, multifarious types of catalysts have been studied, including vanadium phosphorus
oxide (VPO), supported alkali metal/alkaline earth metals, and ionic liquid, . This paper reviewed the
etc
recent achievements on the above catalysts and commented the advantages and disadvantages of the
applied catalysts. The ionic liquid catalyst can be operated at rather low temperature with low energy
consumption and high target product selectivity, whereas the nature of non-continuous homogeneous
catalytic reaction causes the difficulties in product separation and catalyst recycling as well as the low
process efficiency. The VPOs and alkali metal/alkaline earth metals are operated continuously at high
