Description
Montanwachs ist bereits früher der Chlorierung unterworfen worden (vergleiche Deutsche Patentschrift 334 355). Dabei wurde von Rohmontanwachs ausgegangen und in wässriger Suspension chloriert. Je nach dem Chlorierungsgrad wurden spröde bis salbenartige Produkte erhalten. Gegenstand vorliegender Erfindung ist die Gewinnung chlorierter Wachse, ausgehend von gebleichten Montanwachsen, wie sie nach dem Verfahren der Deutschen Patentschrift 510 485 erhalten werden. Die gebleichten Montanwachse stellen Wachssäuren mit einer Säurezahl von über 100 dar.Montan wax has already been subjected to chlorination earlier (see German Patent 334 355). This was based on raw montan wax and chlorinated in aqueous suspension. Depending on the degree of chlorination, brittle to ointment-like products were obtained. The subject of the present invention is the production of chlorinated waxes, starting from bleached montan waxes, as they are obtained by the process of German patent 510,485. The bleached montan waxes are wax acids with an acid number of over 100.
Es wurde nun gefunden, dass man bei der Chlorierung auch in Abwesenheit von Wasser chlorierte Wachse mit äusserst wertvollen Eigenschaften erhält. Die Chlorierung kann in Gegenwart eines Lösungsmittels mit oder ohne Katalysator, wenn notwendig unter Belichtung, durchgeführt werden.It has now been found that chlorination gives chlorinated waxes with extremely valuable properties even in the absence of water. The chlorination can be carried out in the presence of a solvent with or without a catalyst, if necessary with exposure to light.
Die chlorierten Wachse mit einem Chlorgehalt von 30 - 70 % stellen gelbe, gefärbte Produkte dar. Sie besitzen Weichharzcharakter. Nach der Entfernung des bei der Chlorierung entstandenen Chlorwasserstoffs erhält man die Produkte als neutral reagierende Stoffe. Das Halogen ist bemerkenswert fest gebunden. Die Stabilität der chlorierten Produkte kann selbstverständlich durch Zugabe der für diesen Zweck üblichen Stabilisatoren noch erhöht werden.The chlorinated waxes with a chlorine content of 30 - 70% represent yellow, colored products. They have the character of a soft resin. After the removal of the hydrogen chloride formed during the chlorination, the products are obtained as neutrally reacting substances. The halogen is remarkably tightly bound. The stability of the chlorinated products can of course be increased by adding the stabilizers customary for this purpose.
Entsprechend ihren Carbonsäurecharakter lassen sich die chlorierten Wachse in Salze und Ester überführen. Die chlorierten Wachse und ihre Derivate stellen wertvolle Produkte dar, die sich zur Herstellung von Insektenleimen, Lederfetten,Depending on their carboxylic acid character, the chlorinated waxes can be converted into salts and esters. The chlorinated waxes and their derivatives are valuable products that can be used in the manufacture of insect glue, leather fats,
Seifenschmieren, Treibriemenpflegemitteln, Klebstoff bei der Gummireifenherstellung und dergleichen hervorragend eignen.Soap lubricants, drive belt care products, adhesives in rubber tire manufacture and the like are ideal.
Beispiel 1example 1
17 kg gebleichtes Montanwachs mit der Säurezahl 135 werden bei 100° durch Einleiten von trockenem Chlor chloriert. Nach dem Ausblasen von gelöstem Chlorwasserstoff mit Stickstoff erhält man 25,7 kg chloriertes Wachs mit einem Chlorgehalt von 34 %, der Säurezahl 83 und dem Tropfpunkt 21°.17 kg of bleached montan wax with an acid number of 135 are chlorinated at 100 ° by introducing dry chlorine. After blowing out dissolved hydrogen chloride with nitrogen, 25.7 kg of chlorinated wax with a chlorine content of 34%, an acid number of 83 and a dropping point of 21 ° are obtained.
Beispiel 2Example 2
500 g Montanwachs werden in 1000 ccm Tetrachlorkohlenstoff gelöst und durch Einleiten von trockenem Chlor bis zum Nachlassen der Chlorwasserstoffentwicklung chloriert. Man erhält ein Wachs mit einem Chlorgehalt von 70 %. Es hat teegelbe Farbe und honigartige Konsistenz.500 g of montan wax are dissolved in 1000 cc of carbon tetrachloride and chlorinated by introducing dry chlorine until the evolution of hydrogen chloride subsides. A wax with a chlorine content of 70% is obtained. It has a tea-yellow color and a honey-like consistency.
