   Die Beständigkeit eines derartigen   alkoholischen   Gemisches war keineswegs vorauszusehen, denn   hochkonzentriertes Wasserstoffsuperoxyd   ist   bekanntlich   ein Präparat von ausserordentlicher Oxydationskraft, welches viele brennbare Körper direkt entzündet (siehe   Aheggs Handbuch   der anorganischen   Chemie" 190R, 11.

   The decomposition of the hydrogen peroxide proceeds much faster in concentrated solutions, so that up to now one was forced to use hydrogen peroxide

 from soft, for example, fo) gendo may be singled out:
Phosphoric acid, sodium chloride, starch paste (D.R.P. 196700), acylamides (D.R.P. 174190), gelatine (D.R.P. Get, tannic acid (D.R.P. 193370), uric acid (D.R.P. 203019), naphthalene, oxalic acid etc.



     Ks is also known that the shelf life of technical 3% hydrogen peroxide is enhanced by adding 20 g of alcohol or ether to 1 l of liquid
 EMI1.4
 It is also possible to preserve a high-percentage hydrogen peroxide by adding 100% alcohol per liter. It has now actually been shown that a hydrogen peroxide of, for example, 30 percent by weight of H2O2 is sufficient technical purity of this preparation, provided that at least 10 percent by weight of alcohol is added
 EMI1.5
   Alcohol addition to 20 resp. 40% increase.



   The stability of such an alcoholic mixture could by no means be foreseen, because highly concentrated hydrogen peroxide is known to be a preparation of extraordinary oxidizing power, which ignites many combustible bodies directly (see Aheggs Handbook of Inorganic Chemistry "190R, Volume 11, page 89) has now shown that concentrated hydrogen peroxide with 10-100 / o
