摘要：

Changes in the direction of methane conversion as a result of changes in the acidity of magnesium basic oxides caused by varying their phosphorus content, were studied. An increase in phosphorus content and an augmentation of acidity led to a decrease in the speed of dimerization and an increase in the speed of formaldehyde formation. IR spectroscopy showed that catalysts used for methane to formaldehyde conversion are attended by proton centres which are absent on dimerization catalysts.
