Description
1'erfabren zur Darstellung eines wertvollen sulfarierten Derivates von Tallöl. Die direkte Sulfierung von Tallöl, einem Abfallprodukt der Natronzellstoffherstel- lung, wurde bisher noch nicht beschrieben, wahrscheinlich deshalb nicht, weil nach deii üblichen, bekannten Sulfierverfahren voll ständige Zersetzung zu kohligen, unlöslichen Produkten stattfindet.
Es wurde nun gefunden, dass man zu einem wertvollen, sulfierten Derivat von '1'allöl gelangen, kann, wenn man die Behand lung mit sulfurierenden Mitteln bei Anwe senheit von Phenol durchführt, wobei auf 100 Teile Tallöl mindestens 30 Teile Phenol notwendig sind. Man erhält einen har zigen, wasserlöslichen Körper mit vorzüg lichen kapillaraktiven Eigenschaften. geeig net zur Verwendung als Netzmittel in der Textilindustrie; in konzentrierter Form gibt er mit Eisensalzen gefärbte Fällungen, wel che beim Verdünnen mit Wasser glatt löslich sind.
<I>Beispiel:</I> 100 Teile Tallöl werden mit<B>7</B>0 Teilen Phenol verrührt und unter 100 105 Teilen Schwefelsäure 66 Be zugemischt. Man hält die Temperatur des Gemisches auf 85 bis 105 bis zur Wasserlöslichkeit, verdünnt dann mit ungefähr dem gleichen Volumen Wasser und entfernt die überschüssige Schwefelsäure durch Zusatz von Kalk. Durch Umsetzen des entstandenen Kalksalzes mit Soda und Verdampfen der filtrierten Lösung erhält man das Natronsalz einer Sulfosäure als kaum gefärbtes Pulver.
Als Sulfierungsmittel kann Schwefel säure ganz oder teilweise ersetzt werden durch Chlorsulfonsäure oder Oleum.
1'erfabren for the preparation of a valuable sulphated derivative of tall oil. The direct sulphonation of tall oil, a waste product from the manufacture of soda pulp, has not yet been described, probably not because the usual, known sulphonation process completely decomposes to carbonaceous, insoluble products.
It has now been found that a valuable, sulfated derivative of '1'all oil can be obtained if the treatment with sulfurizing agents is carried out in the presence of phenol, at least 30 parts of phenol being necessary for 100 parts of tall oil. A resinous, water-soluble body with excellent capillary-active properties is obtained. suitable for use as a wetting agent in the textile industry; in concentrated form, it gives precipitates colored with iron salts, which are readily soluble when diluted with water.
<I> Example: </I> 100 parts of tall oil are stirred with <B> 7 </B> 0 parts of phenol and mixed with 100 to 105 parts of sulfuric acid 66 Be. The temperature of the mixture is maintained at 85-105 until it is water-soluble, then diluted with approximately the same volume of water and the excess sulfuric acid is removed by adding lime. By reacting the resulting lime salt with soda and evaporating the filtered solution, the sodium salt of a sulphonic acid is obtained as a hardly colored powder.
As a sulfonating agent, sulfuric acid can be replaced in whole or in part by chlorosulfonic acid or oleum.
