Abstract

338,938. Arnold, C., (Harshaw Chemical Co.). July 30, 1929. Drawings to Specification. Sodium bisulphate. - The components of a molten mixture of sodium bisulphate and chromic acid obtained in a process for the manufacture of chromic acid are separated by centrifugal action or settlement, and may then be solidified by spraying or atomizing, or by passage over a cooling drum or travelling band.
