Abstract: 1,199,650. Trioxane. BADISCHE-ANILIN- & SODA-FABRIK A.G. 28 Dec., 1967 [29 Dec., 1966; 26 Oct., 1967], No. 58816/67. Heading C2C. Trioxane is produced by heating aqueous formaldehyde solution in the presence of an acid catalyst in a reactor with simultaneous removal of the product gas containing trioxane, the concentration of catalyst in the reaction mixture being 2-25% by weight of mineral acid or an equivalent amount of another acid, the mean residence time of the aqueous formaldehyde solution in the reactor being from 2 minutes to 2 hours, and the vapour containing trioxane leaving the reactor being brought into contact with substantially completely reacted reaction mixture in a column having at least one theoretical tray.
