Description
Verfahren zur Herstellung eines als Schutz- und Isolierlack, Imprägnier ungsmittel, Klebstoff und dergleichen verwendbaren Harzes. Es wurde gefunden, dass man zu einem als Schutz- und Isolierlack, Imprägnierungsmit tel, Klebstoff und dergleichen, verwendbaren Harz gelangen kann, indem man das durch Schwefelung von a-Naphtol erhaltene Harz mit Benzoylierungsmitteln behandelt.
Die Benzoylierung erfolgt in üblicher Weise, sei es durch Verwendung von Benzoe säurehalogenid bezw. -anhydrid, oder vermit telst der freien Benzoesäure in Gegenwart eines Kondensationsmittels, wie z. B. gasför miger Salzsäure, Thionylchlorid, Phosphor- oder Schwefelhalogenide usw.
Gegebenenfalls kann die Benzoylierung in Gegenwart eines Lösungsmittels, wie z. B. von wässerigem Alkali, Pyridin, Toluol und dergleichen, vorgenommen werden.
Bei der Aufarbeitung des Harzes ist zweckmässigerweise darauf zu achten, dass ein eventueller Säure- oder Alkaliüberschuss, so wie das Lösungsmittel restlos entfernt wer den. Das Trocknen erfolgt vorteilhaft bei möglichst niedriger Temperatur, gegebenen falls unter Verwendung von Vakuum. Das neue Harz ist ebenso wie das AuS- gangsharz von hell- bis braungelber Farbe. Es unterscheidet sich jedoch hiervon durch seine Löslichkeitseigenschaften. Es ist in Al kohol und Alkali unlöslich, in Chloroform, Athylenchlorid und andern halogenierten Kohlenwasserstoffen, ferner in Gemischen von aliphatischen mit halogenierten bezw. mit hydrierten aromatischen Kohlenwasserstoffeu löslich. Das Harz löst sich ferner in einem Gemisch von Aceton und einem nicht lösen den Lösungsmittel, wie z. B.
Alkohol. Unter Mitverwendung gewisser Lösungsmittel, wie z. B. Benzylalkohol, Cyclohexanol und der gleichen, lässt sich das Harz auch in Leinöl lösen. Es ist ferner sehr beständig und wider standsfähig gegen physikalische und chemi sche Einwirkungen, wie z. B. Witterungsein flüsse, mechanische Beanspruchung, elektri sche Spannungsunterschiede und chemische Reagenzien.
Dank dieser Eigenschaften eignet sich das Harz insbesondere als Schutz- und Isolierlack, Imprägnierungsmittel, Klebstoff etc. Zur Er- höhung der Elastizität und des Lösungsver mögens können ihm die üblichen Zusätze, wie z. B. Triphenylphosphat, Cyclohexanol, Kam pher oder Kampherersatzprodukte, ferner Naturharze beigemischt werden. Da es sich weiterhin in gewissen Lösungsmitteln mit Celluloseester und Kautschuli in beliebigen Mengen mischen lässt, kommt es auch als Füllmittel für Celluloseester und Kautschuk fabrikate, sowie als Härtungsmittel für Maut- schuk in Frage.
Seine oben erwähnte Lein öllöslichkeit in Verbindung mit Benzylalkohol und dergleichen, macht das Harz als Email lack geeignet.
Vor den Resinotannolestern, denen das Harz hinsichtlich seiner Eigenschaften ent spricht, zeichnet es sich durch grössere Billig keit aus.
Beispiel 1: 200 Teile des nach dem Verfahren der schweizerischen Patentschrift Nr. 104015 er haltenen a-Naphtol-Sehwefel-Harzes werden mit 45 Teilen Natriumhydroxyd in 1500 Tei len Wasser gelöst und langsam unter Rühren bei einer 8 bis 10' C nicht übersteigenden Temperatur mit 185 Teilen Benzoylchlorid versetzt. Das abgeschiedene Esterharz wird zunächst mit warmem Wasser, dann mit we nig alkoholischem Ammoniak und hernach n ehmals mit Wasser gewaschen, zwecks Ent fernung von Spuren umveresterten Harzes, so wie saurer Verunreinigungen. Unter Vermei dung höherer Temperaturen wird das Ester harz im Vakuum getrocknet.
Beispiel 2: 200 Teile des nach dem Verfahren der schweizerischen Patentschrift Nr. 104015 aus Rohnaphtol und Schwefel erhaltenen Naphtol-Schwefel-Harzes werden pulverisiert und in einem mit Rückflusskühlung und Chlor calciumvorlage versehenen Gefäss im Ölbad unter Rühren mit 185 Teilen Benzoylchlorid und 100 Teilen Toluol versetzt. Bei vorsich tigem Erwärmen und gutem Rühren geht das Harz unter Abspaltung der entsprechenden Menge Salzsäure in Lösung. Die Masse wird so lange weiter erhitzt, bis sieh keine Salz säure mehr entwickelt. Durch eine kurze Va kuumdestillation werden das Toluol und die letzten Spuren Salzsäure, Benzoesäure und Benzoylchlorid entfernt.
Process for the production of a resin which can be used as a protective and insulating varnish, impregnation agent, adhesive and the like. It has been found that a resin which can be used as a protective and insulating varnish, impregnation agent, adhesive and the like can be obtained by treating the resin obtained by sulfurizing α-naphthol with benzoylating agents.
The benzoylation is carried out in the usual way, either by using benzoic acid halide or. anhydride, or mediating the free benzoic acid in the presence of a condensing agent, such as. B. gaseous hydrochloric acid, thionyl chloride, phosphorus or sulfur halides, etc.
Optionally, the benzoylation in the presence of a solvent, such as. B. of aqueous alkali, pyridine, toluene and the like can be made.
When working up the resin, it is advisable to ensure that any excess acid or alkali, as well as the solvent, are completely removed. The drying is advantageously carried out at the lowest possible temperature, if necessary using a vacuum. Like the base resin, the new resin is light to brownish-yellow in color. However, it differs from this in its solubility properties. It is insoluble in alcohol and alkali, in chloroform, ethylene chloride and other halogenated hydrocarbons, and also in mixtures of aliphatic with halogenated or. soluble with hydrogenated aromatic hydrocarbons. The resin also dissolves in a mixture of acetone and a non-dissolving solvent, such as. B.
Alcohol. With the use of certain solvents, such as. B. benzyl alcohol, cyclohexanol and the like, the resin can also be dissolved in linseed oil. It is also very stable and resistant to physical and chemical effects such. B. Witterungsein influences, mechanical stress, electrical voltage differences and chemical reagents.
Thanks to these properties, the resin is particularly suitable as a protective and insulating varnish, impregnating agent, adhesive, etc. To increase the elasticity and the solvent, the usual additives, such as. B. triphenyl phosphate, cyclohexanol, Kam pher or camphor substitute products, and natural resins are added. Since it can still be mixed with cellulose ester and chewing gum in any amount in certain solvents, it can also be used as a filler for cellulose ester and rubber products, as well as a hardening agent for toll gears.
The above-mentioned linseed oil solubility in connection with benzyl alcohol and the like makes the resin suitable as enamel paint.
Before the resinotannol esters, to which the resin corresponds in terms of its properties, it is characterized by greater cheapness.
Example 1: 200 parts of the a-naphthol-sehulfur resin obtained by the process of Swiss Patent No. 104015 are dissolved with 45 parts of sodium hydroxide in 1500 parts of water and slowly with stirring at a temperature not exceeding 8 to 10 ° C 185 parts of benzoyl chloride were added. The separated ester resin is washed first with warm water, then with a little alcoholic ammonia and afterwards with water to remove traces of transesterified resin and acidic impurities. Avoiding higher temperatures, the ester resin is dried in vacuo.
Example 2: 200 parts of the naphthol-sulfur resin obtained from raw naphthol and sulfur by the process of Swiss patent specification No. 104015 are pulverized and 185 parts of benzoyl chloride and 100 parts of toluene are added to a vessel with reflux cooling and calcium chloride in an oil bath while stirring . With careful heating and thorough stirring, the resin dissolves with elimination of the corresponding amount of hydrochloric acid. The mass is heated until no more hydrochloric acid develops. The toluene and the last traces of hydrochloric acid, benzoic acid and benzoyl chloride are removed by a brief vacuum distillation.
