SYNTHESIS OF TRIOXANE IN PRESENCE OF SULFURIC-ACID AND ION-EXCHANGE RESINS AS CATALYSTS - COMPARISONS OF METHODS

There is described a new way of trioxane synthesis with application of cation-exchanger as catalyst and this method is compared to the classical acidic one. It's proved to be feasible to use the cation-exchanger bed for at least a year with no replacement. Trioxane synthesis in presence of cation-exchanger bed occured with the selectivity reaching from 98 to 99,5%, i.e. 4 to 5% better comparing to acidic method.
