Procedure

The procedure of Example 4 is repeated, except with less catalyst (1.9 g, 46% iron), with methacrylic acid (2.0 g) used in place of acrylic acid, and slightly less ethylene oxide added (3.8 g). The reactor is heated to 70° C. for 1 hour. The results for the product hydroxyethylmethacrylate (HEMA) are presented in Table 2.
