Description

Verfahren zur Herstellung von Kondensationsprodukten aus Phenolen und Aldehyden. Bei der weiteren Ausarbeitung des Verfahrens des Hauptpatents 364041: wurde gefunden, daß man teilweise verätherte Polyoxybenzole wie Guajacol oder dessen Homologe mit Aldol bzw. Crotonaldehyd zu wertvollen Harzen und besonders leicht eintrocknenden Ölen kondensieren kann, die in Alkalien und den meisten organischen Lösungsmitteln leicht löslich sind. Die Bedeutung des Verfahrens liegt darin, daß damit auch das Kreosot, welches bekanntlich ein alkalilöslicher Bestandteil des Buchenholzteers sowie auch ein Bestandteil des Teers aus nicht ganz bis zur Kohle abgebauten pflanzlichen Produkten (Braunkohle usw.) und zum Teil auch des Urteers ist, und welches außer aus Phenolen und Kresolen im wesentlichen aus dem Methyläther des Brenzcatechins sowie dessen Homologen, insbesondere dem Kreosol, besteht, zum ersten Male in ein billiges gut eintrocknendes Öl übergeführt ist, das als Ersatz des Leinöls vorteilhaft verwendet werden kann. Beispiel i.Process for the preparation of condensation products from phenols and aldehydes. In the further elaboration of the procedure of the main patent 364041: it was found that partially etherified polyoxybenzenes such as guaiacol or its Homologues with aldol or crotonaldehyde to valuable resins and particularly light Drying oils can condense in alkalis and most organic ones Solvents are easily soluble. The importance of the procedure is that thus also creosote, which is known to be an alkali-soluble component of Beech tar as well as a component of the tar from not quite to coal extracted vegetable products (lignite, etc.) and partly also the primordial tar and which, apart from phenols and cresols, essentially consists of methyl ether of catechol and its homologues, in particular creosol, consists of is converted into a cheap, well-drying oil for the first time as a substitute of the linseed oil can be used advantageously. Example i.

65o Teile Kreosot aus Buchenholzteer werden mit 5o Teilen Salzsäure 37prozentig versetzt. Unter Rühren und Kühlen auf -f- 5 bis -f- io° läßt män allmählich Zoo Teile Crotonaldehyd in das Gemisch einfließen und rührt dann die Reaktionsmasse 48 Stunden bei etwa io bis 2o° gut durch. Das entstehende Produkt wird mehrfach mit Wasser gewaschen, in Äther aufgenommen, die Ätherlösung mit Chlorcalzium getrocknet, filtriert und der Äther abdestilliert. Es bleibt ein viscoses Öl.65o parts of creosote from beech wood tar are mixed with 50 parts of hydrochloric acid 37 percent offset. With stirring and cooling to -f- 5 to -f- io °, you can gradually Add zoo parts of crotonaldehyde to the mixture and then stir the reaction mass 48 hours at about 10 to 20 ° well done. The resulting product will be multiple washed with water, taken up in ether, the ethereal solution dried with calcium chloride, filtered and the ether distilled off. It remains a viscous oil.

Beispiel a.Example a.

i0-4 Teile Guajacol, i5 Teile 24prozentige Salzsäure und 53 g technisches Aldol werden in der in Beispiel i angeführten Weise kondensiert und aufgearbeitet. Es entsteht ein dem entsprechenden Kreosotprodukt ähnliches 01. 10-4 parts of guaiacol, 15 parts of 24 percent hydrochloric acid and 53 g of technical aldol are condensed and worked up in the manner described in Example i. The result is an 01 similar to the corresponding creosote product.
