Abstract

1,130,513. Trioxane. JOSEF MEISSNER K.G. 24 Nov., 1965 [25 Nov., 1964], No. 49912/65. Heading C2C. Trioxane is prepared by distilling in a pressure distillation column an aqueous solution of formaldehyde to concentrate the formaldehyde, passing the resulting hot formaldehyde vapour to a reactor in which the formaldehyde is reacted in the presence of an acid catalyst to form trioxane, and distilling the resultant trioxane from the reaction mixture, at least some of the heat required to distil the trioxane from the reaction mixture being supplied by the formaldehyde required for the trioxaneforming reaction, preferably either by passing hot formaldehyde vapour directly to the reactor or by conducting the hot formaldehyde vapour through a heat exchanger so as to heat the reactor and its contents and then passing the resulting formaldehyde condensate into the reactor.
