Description

Verfahren zur Herstellung von Kondensationsharzen Es ist bekannt, Phenolharz aus Lignin herzustellen. Nach dem vorliegenden Verfahren werden nun die aus dem Lignin auf bekannte Weise gewonnenen Huminsäuren mit Phenolen, wie Phenol, Kresolen, Xylenolen u. ähnl., umgesetzt, wobei die Umsetzung der Phenole mit -den Oxogruppen solcher Huminsä.uren zu Resolen führt. Die Kondensationsreaktionen können sowohl in alkalischem Medium als auch in Gegenwart von sauren Katalysatoren durchgeführt werden. Als solche seien beispielsweise Salzsäure, Phosphorsäure, Borsäure oder sauer reagierende Stoffe, wie Zinkchlorid oder saures Natriumphosphat, ferner organische Säuren, wie Milchsäure, Oxalsäu.re, Trichloressigsäure usw., genannt. Die -erhaltenen Kondensationsprodukte sind beispielsweise in cyclischen Ketonen löslich und eignen sich in besonderem Maße für,die Herstellung Luft- und ofentrocknender Anstrichstoffe. Die aus ihnen erhaltenen Überzüge sind gegen Benzol- und Benzinkohlenwasserstoffe, Alkohole und Wasser unempfindlich. Ferner stellen sie hervorragende Grundstoffe zu Preßmassen dar. Beispiel rooo g Huminsäuren werden mit 16g Natriumhydroxyd in Wasser gelöst und mit 8oo g Phenol verrührt. Nach Hinzufügen von zo ccm konzentrierter Salzsäure wird 3 Stunden mäßig erwärmt, bis sich das Kondensationsprodukt abscheidet. Es wird neutral gewaschen und bei Temperaturen getrocknet, die etwa rro° nicht überschreiten sollen.Process for the production of condensation resins It is known Manufacture phenolic resin from lignin. According to the present procedure, the humic acids obtained from lignin in a known manner with phenols, such as phenol, Cresols, xylenols and the like, reacted, the reaction of the phenols with -den Oxo groups of such humic acids lead to resols. The condensation reactions can carried out both in an alkaline medium and in the presence of acidic catalysts will. As such, for example, hydrochloric acid, phosphoric acid, boric acid or acidic substances such as zinc chloride or acidic sodium phosphate, as well as organic ones Acids, such as lactic acid, oxalic acid, trichloroacetic acid, etc., called. The -received Condensation products are, for example, soluble in cyclic ketones and are suitable especially for the production of air- and oven-drying paints. The coatings obtained from them are against benzene and gasoline hydrocarbons, Insensitive to alcohol and water. They are also excellent raw materials to molding compounds. Example rooo g of humic acids are mixed with 16g of sodium hydroxide in Dissolved water and stirred with 800 g of phenol. More concentrated after adding zo cc Hydrochloric acid is heated moderately for 3 hours until the condensation product separates out. It is washed neutral and dried at temperatures that do not exceed about rro ° should.
