ABSTRACT:
Alkyl esters, such as ethyl acetate, are prepared by contacting the corresponding next lower carbon number alkyl ester, such as methyl acetate, with carbon monoxide and hydrogen in the presence of an iodine or iodide-free catalyst composition comprising a ruthenium-containing compound, a cobalt containing compound and a quaternary phosphonium salt or base, and heating the mixture to an elevated temperature and pressure for sufficient time to produce the desired higher alkyl ester, and then recovering the same from the reaction mixture.
