Abstract
A catalyst composition includes a solid acid catalyst having a multiplicity of acid sites on the surfaces and a multifunctional component coupled to the surfaces of the solid acid catalyst. Each multifunctional component includes at least two functional groups configured to accept a proton from an acid site of the multiplicity of acid sites. The catalyst composition can be used to dehydrate lactic acid, a lactic acid ester, a lactic acid salt, or a combination thereof, to yield a product comprising acrylic acid, an acrylic acid ester, an acrylic acid salt, or a combination thereof.
