Abstract
This invention pertains to the production of glycol monoalkyl ethers and dialkyl ethers by reaction of an aldehyde, and an alcohol with carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt-containing compound and a Group VIB donor ligand.
Claims22
A process for preparing glycol monoalkylethers and dialkylethers which comprises reacting a mixture of hydrogen, carbon monoxide, an aldehyde of the formula:
- RCHO,
- wherein R is selected from the group consisting of hydrogen and alkyl of from 1 to 10 carbon atoms and an alcohol of the formula:
- R'OH,
- wherein R' is alkyl of from 1 to 10 carbon atoms, in the presence of a catalyst comprising a cobalt-containing compound and at least one Group VIB donor ligand at superatmospheric pressures of 500 psi or greater until substantial formation of the said glycol monoalkylethers and dialkylethers has been achieved and recovering the said ethers from the reaction mixture.
