  • Patent number: 11130727
    Abstract: The present invention is directed to a process for the production of methyl acrylate wherein methyl lactate is contacted with a ZSM-5 catalyst in the presence of methanol. It was found that the presence of methanol is essential to obtain a selective process with a high yield. With the process according to the invention methyl acrylate may be obtained as the major product of the reaction, especially if methanol is used as solvent instead of water, while acrylic acid is detected in minor quantity (usually below 10 C %, but often below 5 C %). Methanol may be used as the sole solvent in the process, but preferably also a small amount of water is present in the solvent. In one aspect of the invention, between 1 and 25 wt % of water, based on the total amount of solvent is present.
