Abstract
The present invention relates to a method for making mixtures of ethanol and methanol by reacting methane, water and an acidic aqueous solution of a electron acceptor, preferably Fe.sub.2 (SO.sub.4).sub.3 or Fe(ClO.sub.4).sub.3, having a pH of less than 3, preferably 1 to 3, more preferably 1 to 2 in the presence of a noble metal catalyst, typically platinum or palladium, having a diameter of at least about 100 .ANG. at a temperature of at least 60.degree. C. to about 100.degree. C. The process is advantageous as it provides a method of making ethanol directly from methanol at low cost and high thermodynamic efficiency.
