PROCESS FOR PRODUCING TRIOXANE

摘要

An efficient process for producing trioxane by bringing an aqueous formaldehyde solution into contact with an acidic catalyst, wherein the conditions are controlled so that the concentrations of methanol and formic acid in the reaction mixture are each 0.5 to 5 wt.% and the methanol concentration (wt.%) does not exceed twice the formic acid concentration (wt.%). This process is reduced in the corrosion of the equipment and formation of by-products.
