UNITED STATES PATENT OFFICE.
PAiUI' ROSER, OF ESSLINGEN, GERMANY.
PROCESS FOR PRODUCING SODIUM PEROXID COMPOSITIONS FOR WASHING AND BLEACHING PURPOSES.
965,016. No Drawing.
Patented July 19, 1910.
To all whom it may concern:
Be it known that I, PAUL Rosnn, a, citizen of the German Empire, residing at Esslingen, in the Kingdom of Wiirtemberg, Empm of Germany, have invented certain new and useful Improvements in Processes for Producing a Sodium Peroxid Composition for Washing and Bleachin Purposes; and I do hereby declare the 0 lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an improved process for enabling sodium eroxid to be produced in a form better a opted for washing and bleaching purposes than has hitherto been the case.
Various disadvantages have been found in the use of sodium peroxid for washing and bleaching purposes' For instance, in the first place such a rapid violent and frequently explosive decomposition takes place on its contact with water that the nascent oxygen, which thus escapes much too rapidly, is only ver incompletely utilized, and further the oxi izing action of the sodium peroxid when it comes in contact with the substances to be washed or the material to be bleached, is frequently so strong, that the articles 1n questlon are burned, and the handling of the sodium peroxid generally necessitates the (greatest precaution. These properties of so ium peroxid therefore render its practical use for laundr and bleachin purposes extremely diflicu t.
low this improved process has for its object to remove these unfavorable properties from sodium peroxid, and by the rescnt invention this is done by the sotium 'peroxid being mixed with tetrachlorid of carbon until the mixture attains a pasty consistency, while a decomposition o the components either does not take place at all or only to a very inconsiderable extent. The pasty roduct thus obtained has in contrast to ordinary sodium peroxid, the advanta e that, when placed in water, it immediate y sinks, and under the protecting covering of the tetrachlorid of carbon only slowly and uniformly decom oses under the surface of the water. By his means a better utlhzation of the bleaching oxygen is possible than was the case with the previous sudden decomposition. The tetrachlorid of carbon contained in the product also prevents any scorching or burning of organic substances, even when brought into direct contact with the preparation, and entirely deprives the sodium peroxid of its combustion producing tendencies, while on the other, hand in consequence of its grease and resin dissolving properties, it considerably assists tlie cleanmg power of the sodium peroxid 1n the washing or bleaching bath.
In all cases in which the caustic soda formed by the decomposition of the sodium peroxid might have a deleterious action, the free alkali may be rendered artially or wholly innocuous by the additlon of suitable substances, such as sodium bicarbonate, boric acid and the like. These additions have also the advantage that the mass which is. pasty without this addition, assumes a moist pulverulent condition by which the empt ing of the vessels in which it is conveye is considerably facilitated, so that it is' no longer necessary to wash them out with water.
Other chlorin substitution products of the paraflin series which behave similarly to tetrachlorid of carbon may also be employed in the same manner.
Example 1: parts of finely pulverized sodium peroxid are mixed in a mixing drum with 45 parts of tetrachlorid of carbon until a homogeneous paste is formed.
Example 2: 62 parts of finely pulverized sodium peroxid are treated in a mixing drum with 100 parts of tetrachlorid of carbon, 168 parts of sodium bicarbonate are added to the resultant thin paste, and the mass is mixed until it assumes a uniform moist pulverulent condition.
I declare that what I claim is 1. A process for producing a sodium peroxid composition suitable for washing and bleaching urposes, consisting in a noncombustible ch orin substitution product of the parafiin series, such for instance as tetrach orid of carbon, being added to the sodium peroxid until a past constituency is obtained, substantially as escribcd.
2. A process for producing a sodium peroxid composition for washing and bleaching pin-poses consisting in adding to a paste of sodium peroxid and a noncombustible ries sodiumfbicarbonate for neutralizing the chlorin substitution product of the arafiin free alkali.v serios a substance for neutralizing e free In testimony whereof I afiix my signaalkali of the soda. ture, in presence of two witnesses. 5' 3. A process for producing a sodium per- PAUL ROSER.
