Abstract
A method for the selective cleavage of a compound comprising an aromatic ring and a C—O—C linkage in the presence of a heterogeneous catalyst is provided. The heterogenous catalyst may be a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.
Claims15
A method of cleaving a C—O bond in a compound, comprising contacting the compound with a hydrogen source in the presence of a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine, wherein the compound comprises an aromatic ring and a C—O—C linkage, thereby cleaving the C—O bond in the C—O—C linkage.
A mixture comprising:
- i. a compound comprising an aromatic ring and a C—O—C linkage;
- ii. a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine;
- iii. a hydrogen source;
- iv. optionally a solvent;
- v. optionally a zeolite having LTA, FAU, BEA, MFI or MOR framework.
