Description

Verfahren zur Darstellung von harzartigen Kondensationsprodukten aus Phenolalkyläthern und Formaldehyd. lin Hauptpatent 35$399 sind harzartige Kondensationsprodukte beschrieben, welche durch Kondensation von Formaldehyd mit in in-Stelfung durch eine Alkyl- oder eine weitere Alkoxygruppe substinferten Phenolalkyläthern entstehen, und die sich besonders durch ihre. Löslichkeit in Terpentinöl und Leinöl auszeichnen.Process for the preparation of resinous condensation products Phenol alkyl ethers and formaldehyde. lin main patent 35 $ 399 are resinous condensation products described, which by condensation of formaldehyde with in-Stelfung by an alkyl or another alkoxy group substituted phenol alkyl ethers are formed, and which are particularly characterized by their. Distinguish solubility in turpentine oil and linseed oil.

Es wurde nun weiter gefunden, daß auch die Alkyläther von ar.-Tetrahydronaphtholen, die beispielsweise durch Sulfonieren von Tetrahydronaphthalin, Verschmelzen der Sulfosäuren und nachträgliche Alkylierung leicht erhalten werden können, harzartige Kondensationsprodukte von ganz ähnlichen Eigenschaften liefern. Die Produkte stellen helle, springharte Harze dar, die unlöslich in Alkohol, Amylalkohol, löslich in Benzol, Chlorbenzol, Cvklohexanol, Cyclochexanon, ferner in Terpentinöl und Leinöl sind. Sie lassen sich daher mit Vorteil an Stelle von natürlichen Harzen verwenden.It has now been found that the alkyl ethers of ar-tetrahydronaphthols, for example by sulfonating tetrahydronaphthalene, fusing the Sulphonic acids and post-alkylation can easily be obtained, resinous Provide condensation products with very similar properties. Make the products light-colored, spring-hard resins that are insoluble in alcohol, amyl alcohol, soluble in Benzene, chlorobenzene, cyclohexanol, cyclohexanone, also in turpentine oil and linseed oil are. They can therefore be used with advantage in place of natural resins.

Beispiel. 162 Teile ar.-Tetrahydro-ß-naphtholmethyläther (leicht bewegliche, farblose Flüssigkeit von schwachem angenehmem Geruch vom spezifischen Gewicht r,o4, siedet bei a50°) werden mit 165 Teilen Formaldehyd (3oprozkntig) und ro Teilen konzentrierter Schwefelsäure mehrere. Stunden auf ioo° erwärmt. Zur Entfernung geringer Mengen nicht kondensierter Anteile wird gegebenenfalls mit Wasserdampf abgeblasen und das entstandene Kondensationsprodukt durch Waschen mit Wasser von der Säure befreit. Nach dem Entwässern erhält man ein helles, springhartes Harz.Example. 162 parts ar-tetrahydro-ß-naphthol methyl ether (easily mobile, colorless liquid with a faint, pleasant smell of specific gravity r, o4, boils at a50 °) are concentrated with 165 parts of formaldehyde (3 percent) and ro parts Sulfuric acid several. Heated to 100 ° for hours. For removing small amounts Uncondensed parts are blown off with steam if necessary and that resulting condensation product freed from the acid by washing with water. After dehydration, a light-colored, spring-hard resin is obtained.
