PROCESSES FOR MAKING METHACRYLIC ACID |
| 摘要 |
Processes are described for making methacrylic acid via methacrolein from a biobased isobutene, wherein the biobased isobutene is prepared from ethanol or from acetic acid in the presence of a ZnxZryOz mixed oxide catalyst, the biobased isobutene is oxidized to methacrolein and the methacrolein is further oxidized to methacrylic acid. |

1. A process for making methacrylic acid via methacrolein from a biobased isobutene, comprising converting acetic acid to isobutene in the presence of a mixed oxide catalyst comprised of oxides of Zn and Zr in which the ratio of Zn:Zr is from about 1:100 to about 10:1, oxidizing the isobutene to methacrolein with a source of oxygen in the presence of a catalyst and further oxidizing methacrolein to methacrylic acid with a source of oxygen in the presence of a catalyst. |
