Filed: 1949-07-11
Abstract: <PICT:0668874/III/1> In the rectification of aqueous solutions of hydrogen peroxide to a high degree of concentration, e.g. 90 per cent, the hazards of thermal decomposition are lessened by reboiling the highly-concentrated solution at the base of the rectification column, using at least two superposed, heating-pans in which the quantity of solution is present in small amount.  Aqueous hydrogen peroxide (35 per cent) supplied through pipe 1, is vaporized in coil 2 which is heated by steam passing through box 3; and the vapours, having passed through liquid-trap 6, enter the rectification column through pipe 7.  The column is provided with Raschig rings or bubble-plates, and with a reflux-condenser 8. The lower part of the column is provided with three hollow pans having bubble -caps and overflow pipes, heated by steam supplied through pipes 10 and exhausted through pipes 11.  The overflow pipes are arranged so that only a shallow layer of concentrated hydrogen peroxide is present on each pan.  The highly concentrated product is discharged from the base of the column through cock 12; the actual strength may be controlled by the rate of supply of cooling-water to the reflux-condenser.  Withdrawal pipes may be inserted at different heights of the reboiling pans in order to obtain peroxide solutions of various strengths.
