Abstract

1. A process for the continuous manufacture of trioxane, optionally together with cyclic formals, from aqueous formaldehyde solutions containing optionally at least one diol and/or at least one epoxide, in the presence of acidic catalysts, in a circulation reactor with evaporator, at a residence time in the range of from 2 to 240 minutes, wherein the amount of vapor leaving the system is from 0.1 to 4% relative to the total amount of circulating product.
