Abstract
A 1,3-diol is obtained by a process comprising reacting, at an elevated temperature, methanol with m-dioxane, or an alkyl derivative thereof, in the presence of an insoluble solid acid catalyst, displacing the equilibrium by distilling off the methanol/methylal azeotrope as quickly as it is formed and separating the 1,3-diol produced by fractional distillation. Suitable catalysts are, for example, tungstic acid, molybdic acid and, particularly, a cation-exchange resin containing acidic groups, especially those containing sulphonic acid groups. The reaction temperature should not be so high as to result in the decomposition of the catalyst. The reaction may be carried out continuously or otherwise and may be represented by the following example <FORM:0824551/IV (b)/1>
