Procedure

A 50 milliliter portion of this recovered catalyst is tested in continuous operation for 24 hours under the conditions outlined in Example 2. Formaldehyde conversion to pivalolactone averages 50 percent with 10 percent going to isobutyroxypivalic anhydride. Isobutyric anhydride yield for the same period averages 75 percent to pivalolactone and 20 percent to isobutyroxypivalic anhydride.
