Abstract
12,781. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. June 22. Sulphuric anhydride.-To obtain a practicallytheoretical yield of sulphuric anhydride by the contact process with a much smaller quantity of platinum, the processes described in Specifications No. 183, A.D. 1855, and No. 15,949, A.D. 1898, are combined, i.e., the production is carried on in two or more contact apparatus, so that about 80 to 90 per cent. of the sulphur dioxide is converted in the first contact apparatus, and the sulphuric anhydride formed absorbed before passing the gases to the second apparatus, while each apparatus has a device for regulating the temperature.
