Abstract
1,265,012. A process for the production of trioxane. DEUTSCHE GOLD-UND SILBERSCHEIDEANSTALT. 14 March, 1969 [27 April, 1968], No. 13535/69. Addition to 1,064,014. Heading C2C. In the production of trioxane from aqueous formaldehyde solutions by heating in the presence of an acid catalyst and an inert oil component and distilling off the trioxane formed, the foam-formation is eliminated by the addition to the reaction mixture of an anti-foam agent in conjunction with one or more metal salts.
