Abstract
The method uses a starting material which is a liquid mixture consisting of a formaldehyde proportion comprised between 48 and 55 % by weight, a methanol proportion comprised between 20 and 30 % by weight and a water proportion comprised betweeen 32 and 15 % by weight; the liquid mixture is obtained from a tapping which is effected from a plant for the continuous preparation of urea-formaldehyde resins and glues, immediately after having subjected the methanol to catalytic oxidation via air, condensation of the gases evolving from said catalytic oxidation and separation between condensed products and uncondensed gases. These solutions may be applied to formaldehyde reactions wherein it is of interest to reduce the amount of water present in conventional solutions and also to use the methanol for example as solvent for the final product obtained.
