ABSTRACT:
This invention concerns a process for preparing ethylene glycol and lower monohydric alcohols comprising contacting a mixture of carbon monoxide and hydrogen with a catalyst comprising a ruthenium-containing compound and a copper- or silver-containing compound, both dispersed in a low-melting quaternary phosphonium salt and heating the resulting mixture at an elevated temperature and moderate pressure for sufficient time to produce the desired ethylene glycol.
