Procedure

A reaction feed comprising acetic acid (9.1%), formaldehyde (17.3%), methanol (6.7%), water (38%), oxygen (4.06%), and nitrogen (24.8%) was passed through a fixed bed reactor comprising the Catalyst 1 and Comparative Catalyst A. The reaction was conducted at three temperatures, 340° C., 355° C., and 370° C. Acrylic acid and methyl acrylate (collectively, “acrylates”) were produced. The conversions, selectivities, and space time yields are shown in Table 4.
