A novel and very economical method for the industrial production of ethyleneglycol starting with formaldehyde and synthesis gas, i.e. a gaseous mixture of carbon monoxide and hydrogen, is provided. The method utilizes the synthetic route in which a formaldehyde di-sec-alkyl acetal, which is obtained from formaldehyde and a sec-alcohol, is reacted with carbon monoxide and hydrogen to form an ethyleneglycol mono-sec-alkyl ether which is then hydrolyzed with water into the desired ethyleneglycol. The first step reaction of the acetal compound is catalyzed with a single component catalyst of cobalt carbonyl while the hydrolysis reaction proceeds with an acidic catalyst in a high yield unexpected from the similar reaction ethyleneglycol mono-primary-alkyl ethers. |
