Description
Patented May 20, 1930' UNITED, STATES) PATENT OFFICE GUSTAV BAUH, OF WEISSlEZNSTEIN-ON-THE-DRAU, AUSTRIA, ASSIGNOB TO CHEHISCHE FABRIK WEISSENSTEIN' G. M. B. IL, 01' CABINTHIA, AUSTRIA STABILIZED PEROXDE' SOLUTION ll'o Drawing. Application filed October 12, 1927, Serial No. 225,834, and in Austria September 16, 1928.
This invention relates to the preservation and use of peroxide solutions. It has for 1ts object the preparation of peroxide solutlons which are stabilized against decomposition for example, which tend to conserve theoxygen and activate or catalyze the peroxide action; the oxygen' oss from the baths, however, has remained high. In these practices, only the stabilization alone of solutions during transportation etc. has been effected by the additions at the time of manufacture, while the second activating action is secured by additions to the bleach bath, and the like.
I have found that for use in bleaching peroxide solutions may be stabilized by any of the above substances, but that the stabilizer causes a lowering of the bleaching power. On the other hand, I have found that activated peroxide bleach baths oftenproduce good bleaching effects but that the consumption of active oxygen is high.v
I have now discovered that peroxide solutions, specifically hydrogen peroxide solutions, can be prepared which are not only stabilized against decomposition during shipment, storage, and dilution precedent to use, but the bleaching action is also activated during use so that the loss of unused oxygen is low. This I accomplish by the addition to the peroxide solution, at the time of manu facture, of one or more of each of a stabilizing and activating substance. I have found during the use of such solutions as for example in bleaching, that the stabilizing and oxygen activating substances act reciprocally on each other to assist in their respective specific actions.
I have found that hydrogen peroxide solutions containing a plurality of such materials, i. e., one or more of each of a stabilizer and to be bleached, and which ordinarily would produce a decided loss by catalytic action.
Finally, I have found, that these peroxide solutions have the same chemical action bleaching as ordinary solutions ofperoxide alone; cause very little loss of active oxygen from the actual bleaching process; are stable to shipment and storage in warm climates; do not injure materials to be bleached; may be diluted for use without loss of active oxygen; eliminate the necessity for special additions at the time of preparing a bleaching bath; give better bleaching results with less peroxide consumption; and may be used While containing the same additions in the same proportions for every type of bleachmg.
The results mentioned above may be obtained to an extraordinary degree by the simultaneous addition to peroxide solutions of a combination such as sodium pyrophosphate, sodium silicate, and sodium chloride, or of various combinations of sodium pyrophosphate, sodium chloride,'chlorinated hydrocarbons, colloidal materials, Turkey red oil, Water glass, etc However, I wish it expressly understood that. the present invention is' not to be limited to these specific additions nor to the examples given below. On' the other hand, any combination of stabilizers and activators for peroxide solutions resulting in a mutual action which increases the power of each during the reaction of the peroxide with other substances, and which produces a stabilizing action on the solution when not in use, should be considered as belonging to the presentinvention.
The following are given as examples:
Emam-ple 1 after being kept six weeks at 35 to 40 C.
Such a solution diluted to 3% and kept either acid, neutral or alkaline showed a better bleaching effect upon straw after six hours at C. than a 3% solution of peroxide alone. The consumption of peroxide was about 15 to 17% of the original, whereas over of the original peroxide was used in an alkaline 3% solution of ordinary peroxide.
Example 2 7 To a 30%solution of hydrogen peroxide there was added 2.5% of Na P O .1OH O, 0.5% NaCl, and 1% of water glass. The slight acid reaction of the solution was restored with phosphoric acid. After heating at 70 C. for several hours scarcely any decomposition had resulted, Whereas a solution of peroxide 'of the same concentration but with no addition showed a loss of 2.3%. A solution made up according to this example and diluted to 0.5% showed only 10 to 20% decomposition of peroxidewith a good bleaching eflect on Wool at 40 to 50 G. for about five hours. However, a peroxide solution of the same concentration; which had not been treated -as the above, decomposed quickly and completely without any noteworthy bleaching action.
Emample 3 The solution is'made slightly acid with phosphoric acid. This solution is also stable toward shipment and practically no loss of peroxide could be detected after heating it three hours at 7 0 C.
Some felt was bleached by diluting this 30% solution to 2%, making it slightly ammoniacal, and heating to 50 C. for five hours. The bleaching action was very good and only about 20% of the original peroxide was consumed.
Claims:
1. Peroxide solution containing sodium pyrophosphate and an alkali metal halide.
2. Hydrogen peroxide solution containing sodium pyrophosphate and sodium chloride.
3. Hydrogen peroxide solution containing sodium pyrophosphate, sodium chloride and a. colloidal material.
September, 1927.
