Abstract
The present invention relates to a process for the alkoxylation of a monool with at least one alkoxylating agent to an alkoxylated alcohol wherein a catalyst is employed which comprises a metallo-organic framework material of metal ions and at least bidentate coordinately bound organic ligands.
Claims8
A process, which comprises:
- alkoxylating a monool with at least one alkoxylating agent to obtain a polyoxyalkylene alcohol comprising 1 to 5 alkoxy units in the presence of a catalyst comprising a metallo-organic framework material of metal ions and at least bidentate coordinately bound organic ligands, wherein the bidentate coordinately bound organic ligands are selected from the group consisting of an hydroxy-substituted aromatic mononuclear polycarboxylic acid, an hydroxyl-substituted polynuclear aromatic polycarboxylic acid, an hydroxyl-substituted aromatic mononuclear polycarboxylic acid comprising at least one heteroatom, an hydroxy-substituted aromatic polynuclear polycarboxylic acid comprising at least one heteroatom, and combinations thereof.
