Description
Verfahren zur Herstellung härtbarer und löslicher Kondensationsprodukte aus aromatischen Aminen und Formaldehyd Gegenstand des Hauptpatents 598 444 ist ein Verfahren zür Herstellung härtbarer und löslicher Kondensationsprodukte, bei dem die Einwirkung von Formaldehyd auf Anilin in alkoholischer Lösung bei Gegenwart einer mehrbasischen organischen Säure, insbesondere Phthalsäure, geg'eb'enenfalls unter Zusatz einer Kontaktsubstanz erfolgt.Process for the production of curable and soluble condensation products from aromatic amines and formaldehyde is the subject of main patent 598 444 a process for the production of curable and soluble condensation products which the action of formaldehyde on aniline in alcoholic solution in the presence a polybasic organic acid, in particular phthalic acid, if necessary takes place with the addition of a contact substance.
Die vorliegende Erfindung betrifft eine weitere Ausbildung dieses Verfahrens, die darin besteht, daß an Stelle des Anilins hier [3-Naphthylamin zur Umsetzung gebracht wird.The present invention relates to a further embodiment of this Process which consists in that instead of the aniline here [3-naphthylamine for Implementation is brought.
Beispiel 42,9 g ß-Naphthylamin, 9,9 g Phthalsäure und o, i g Natriumstannichlorid werden in ioo ccm Alkohol gelöst. Diese Lösung wird auf 40` erwärmt und mit ioo ccm einer Boo/oigen Formaldehydlösung versetzt. Durch die Reaktionswärme steigt die Temperatur ungefähr bis auf 75° an; unter tüchtigem Rühren läßt man langsam erkalten. Nach 2 Stunden wird zur Vervollständigung der Abscheidung des Harzes destilliertes Wasser zugegeben, bis ein weiterer Zusatz keinen Niederschlag mehr hervorruft. Dann läßt man 24 Stunden absitzen, gießt die wäßTige Mutterlauge ab, sammelt das Harz und wäscht es. Auch ohne Zusatz von Wasser setztsich das gebildete Harz nach geraumer Zeit von selbst ab. Das erhaltene Harz ist bei gewöhnlicher Temperatur pulverförmig, und @es unterscheidet sich somit von den Harzen, die aus Anilin, Toluidin u. dgl. in derselben Weise hergestellt werden. Die mit den letzteren erhältlichen Harze sind klebrig und zähflüssig und machen eine Reinigung mit 40 % igem Alkohol notwendig. Eine solche Behandlung erübrigt sich im vorliegenden Falle. Das pulverförmige Harz ist in Benzol, Aceton, Chloroform, Anilin :oder einem Gemisch von 2 Teilen Benzol und i Teil Alkohol löslich. Auch in Eisessig löst es sich auf. Man kann die Lösung zur Imprägnierung von Füllstoffen benutzen und beispielsweise 45 g getrocknetes Holzmehl mit einer Lösung tränken, die -45 g Harz und 75 ccm Benzol :enthält. Nach dem Verdunsten des Lösungsmittels wird das Harz durch Hitze unter Druck gehärtet, beispielsweise bei etwa ioo bis i5o° und einem Druck von Zoo bis 5oo at.Example 42.9 g of β-naphthylamine, 9.9 g of phthalic acid and 0.1 g of sodium stannous chloride are dissolved in 100 cc alcohol. This solution is heated to 40 'and ioo ccm of a boo / oigen formaldehyde solution. The heat of reaction increases the temperature up to about 75 °; leave slowly while stirring vigorously to cool off. After 2 hours, distillation is carried out to complete the deposition of the resin Water added until another addition no longer causes precipitation. then It is allowed to settle for 24 hours, the aqueous mother liquor is poured off and the resin is collected and washes it. Even without the addition of water, the resin formed sets after a considerable amount of time Time by itself. The resin obtained is powdery at ordinary temperature, and @it is thus different from the resins made from aniline, toluidine and the like. can be made in the same way. The resins obtainable with the latter are sticky and viscous and require cleaning with 40% alcohol. Such a treatment is unnecessary in the present case. The powdery resin is in benzene, acetone, chloroform, aniline: or a mixture of 2 parts benzene and i part alcohol soluble. It also dissolves in glacial acetic acid. One can have the solution use to impregnate fillers and, for example, 45 g dried Soak wood flour with a solution that contains -45 g of resin and 75 cc of benzene: To the evaporation of the solvent, the resin is hardened by heat under pressure, for example at about 100 to 150 degrees and a pressure of zoo to 500 at.
