Description

Verfahren zur Verbesserung von Bitumenemulsionen Das Hauptpatent 8oo 667 betrifft ein Verfahren zur Herstellung von wäßrigen Dispersionen, wobei zur Verbesserung der Haltbarkeit außer anderen dispergierend wirkenden Stoffen oberflächenaktive Salze der Oxydationsprodukte von festen Brennstoffen zugesetzt werden.Process for improving bitumen emulsions The main patent 8oo 667 relates to a process for the preparation of aqueous dispersions, for Improvement of the shelf life as well as surface-active substances with a dispersing effect Salts of the oxidation products of solid fuels are added.

Es wurde nun gefunden, daß man zur Verbesserung der Eigenschaften, insbesondere der Wasserfestigkeit von Emulsionen von bituminösen Stoffen, wie hochsiedenden Kohleteerölen, Destillationsrückständen von Erdölen, Olextrakten oder anderen asphalt- und harzhaltigen Olen, in Wasser, die unter Verwendung der üblichen Emulgatoren hergestellt wurden, statt der im Hauptpatent genannten Salze oder zusammen mit diesen kleine Mengen, etwa o,5 bis 7°;0, vorteilhaft i bis 5°;'0, der oxydierten festen Brennstoffe selbst verwenden kann.It has now been found that to improve the properties, in particular the water resistance of emulsions of bituminous substances such as high-boiling substances Coal tar oils, distillation residues from petroleum, oil extracts or other asphalt and resinous oils, in water, made using the usual emulsifiers instead of the salts mentioned in the main patent or together with them small amounts, about 0.5 to 7 °; 0, advantageously 1 to 5 °; '0, of the oxidized solids Can use fuel itself.

Als feste Brennstoffe kommen vor allem Braunkohle und Torf in Betracht. Diese werden z. B. mit konzentrierter Salpetersäure bei 3o bis 7o' unter Rühren behandelt oder mit Hilfe von Chlor, Chlorkalk, Kaliumpermanganat oder Luft oxydiert.Lignite and peat in particular come into consideration as solid fuels. These are z. B. with concentrated nitric acid at 3o to 7o 'with stirring treated or oxidized with the help of chlorine, chlorinated lime, potassium permanganate or air.

Emulgatoren, die besonders günstig mit den oxydierten Brennstoffen zusammenwirken, sind vor allem die durch Sulfonieren hochsiedender bituminöser Stoffe, insbesondere von Steinkohlenteerrückständen gewonnenen, in wäßrigem Ammoniak gelösten Produkte. Beispiel In einen auf ioo bis i2o° erhitzten Destillationsrückstand eines Erdöls läßt man langsam unter Rühren 4o bis 5o' heißes Wasser einlaufen, dem ein durch Sulfonieren von Steinkohlenteerrückstand hergestellter, in wäßrigem Ammoniak gelöster Emulgator und ein mit Ammoniak behandeltes Oxydationsprodukt von Braunkohle zugesetzt sind. Dem entstehenden viskosen; homogenen Brei wird noch so viel von der wäßrigen Phase zugegeben, bis die Emulsion einen Wassergehalt von 5o0/0 aufweist. Zur Verbesserung der Wasserfestigkeit und Haltbarkeit werden der Emulsion etwa i bis 30/0 einer mit Salpetersäure behandelten Braunkohle zugegeben. Diese erhält man, indem man zu iooo Gewichtteilen fein gemahlener Braunkohle mit einem Wassergehalt von etwa i2°/0 innenhalb einer Stunde 35o Gewichtteile 350/ßige Salpetersäure zugibt, wobei durch starke Außenkühlung die Temperatur auf etwa 45' gehalten wird.Emulsifiers, which are particularly beneficial with the oxidized fuels work together, are above all those caused by sulphonation of high-boiling bituminous substances, in particular obtained from coal tar residues dissolved in aqueous ammonia Products. Example In a distillation residue heated to ioo to i2o ° a Petroleum is slowly poured in hot water from 4o to 5o 'while stirring produced by sulfonating coal tar residue in aqueous ammonia dissolved emulsifier and an oxidation product of lignite treated with ammonia are added. The resulting viscous; homogeneous porridge will still be so much of the aqueous phase is added until the emulsion has a water content of 5o0 / 0. To improve water resistance and durability, the Emulsion added about 1 to 30/0 of a brown coal treated with nitric acid. This is obtained by adding 100 parts by weight of finely ground brown coal a water content of about 12 ° / 0 within an hour 35o parts by weight 350 / ßige Nitric acid is added, whereby the temperature is reduced to about 45 'due to strong external cooling. is held.

Man erhält eine Emulsion, die für den Straßenbau sowie zum Isolieren und Anstreichen, zum Wasserfestmachen gut geeeignet istund eine unbegrenzte Haltbarkeit hat.An emulsion is obtained that can be used for road construction and for insulation and painting, is well suited for waterproofing and has an unlimited shelf life Has.
