Abstract: This invention produces methyl esters and ethylene glycol esters by reacting carbon monoxide and hydrogen in a homogeneous liquid phase mixture containing a ruthenium carbonyl complex catalyst and an acyl compound. Methyl ester and ethylene glycol ester are the predominant products. These esters are used as precursors in the formation of ethylene glycol, vinyl acylates such as vinyl acetate, ethylene oxide, ethylene carbonate and methanol.

Abstract: In processes for the hydrolysis of alkylene oxide to form alkylene glycols in the presence of selectivity-enhancing organometalate wherein the organometalate is provided in a water-insoluble phase, a stabilizing material is used to enhance the stability of the organometalate. The stabilizing material is water-soluble and comprises a cation and a selectivity-enhancing metalate anion.

Abstract: Alkylene oxides are hydrolyzed in a reaction menstruum containing an aqueous phase, a water-immiscible liquid phase, and a selectivity-enhancing, dissociatable metalate anion-containing material. The concentration of the metalate anion-containing material is greater in the water-immiscible liquid phase than that in the aqueous phase. The water-immiscible liquid phase can be separated from the aqueous phase to recover metalate anion-containing material.

Abstract: The process for the liquid-phase hydration of a vicinal alkylene oxide(s) to the corresponding alkylene glycol(s) comprising carrying out such hydration in the presence of vanadate anion and a selectivity-enhancing amount of carbon dioxide.

Abstract: A continuous process for making alkylene glycols by the hydrolysis of alkylene oxides in the presence of selectivity-enhancing organometalate wherein the alkylene glycol-containing hydrolysis product contains organometalate comprises recovering organometalate by extraction with a water-immiscible solvent, separating the resulting organometalate-containing solvent into an organometalate-lean stream for reuse in the extraction and an organometalate-rich stream for reuse in the hydrolysis.
