Abstract
Provided herein is a process for producing a compound of formula (I), or a salt thereof: (I) catalyst. Also provided herein are catalysts which find use in the process.
Claims58
A process for producing a compound of formula (I), or a salt thereof:
- wherein R1 is H or methyl, comprising:
- a) reacting a methyl halide in the presence of hydrogen, carbon dioxide and a catalyst selected from the group consisting of i) an iron- and carbon-containing catalyst, and ii) a cobalt- and carbon-containing catalyst, to produce acetic acid and/or a salt thereof;
- or
- b) reacting a methyl halide with carbon monoxide in the presence of a catalyst selected from the group consisting of i) an iron- and carbon-containing catalyst, and ii) a cobalt- and carbon-containing catalyst, to produce acetic acid and/or a salt thereof;
- c) reacting hydrogen and carbon dioxide in the presence of a catalyst selected from the group consisting of i) an iron- and carbon-containing catalyst, and ii) a cobalt- and carbon-containing catalyst, to produce formic acid and/or a salt thereof;
- or
- d) reacting hydrogen and carbon dioxide in the presence of a cobalt- and carbon-containing catalyst to produce acetic acid and/or a salt thereof;
- wherein the iron- and carbon-containing catalyst comprises Fe (0) sites and Fe (II)/(III) sites;
- and wherein the cobalt- and carbon-containing catalyst comprises Co (0) sites and Co (II) sites.
6 more elements
An iron- and carbon-containing catalyst, wherein the catalyst comprises Fe (0) sites and Fe (II)/Fe (III) sites, and wherein:
- e) the iron particles have a mean equivalent particle diameter of up to 9.8 nm, and/or a mean particle long axis of up to 9.8 nm;
- and/or
- f) the catalyst has more than 45 wt % iron, and has a hydrogen content in the range of from 0.4 to 0.8 wt %;
- and/or
- g) the catalyst comprises an SBET value of at least 150 m2 g−1;
- and/or
- h) the catalyst is a thermally treated iron-containing metal-organic framework (MOF), which has been thermally treated under a hydrogen-containing atmosphere.
4 more elements
A cobalt- and carbon-containing catalyst, wherein the catalyst comprises Co (0) sites and Co (II) sites.
