Description
Verfahren zur Darstelluneines als Schutz- und Isollerlack, Imprägnierungsmittel, o Klebstoff und dergleichen verwendbaren Harzes.
Gemäss .dem Zusatzpatent Nr. 104247 kann man zu einem als Schutz- und Isolier-- lack, Imprägnierungsmittel, Klebstoff und dergleichen verwendbaren Harz gelangen, in dem man das durch Schwefelung von a-Naph- thol erhaltene Harz ,mit Benzoylierungsmit- teln behandelt.
Es wurde nun gefunden, dass es nicht notwendig ist, von dem fertigen alkali- und alkohollöslichen Schwefelharz auszugehen und dasselbe durch Benzoylierung in das Esterharz überzuführen, sondern, dass es möglich ist, den Verharzungsprozess und die Veresterung in einem Arbeitsgang durchzu führen, indem man das als Ausgangsstoff des genannten Schwefelharzes dienende a Naphthol, gegebenenfalls in Gegenwart von Wasser,
wässerigen Alkalien oder andern Lö- sungs- oder Verdünnungsmitteln gleichzeitig mit Schwefelhalogeniden und Benzoylierungs- mittedn bezw. .mit Gemischen beider behan delt.
Die Reinigung des so erhaltenen Harzes erfol,-t wie im Hauptpatent angegeben. Die Eigenschaften dieses Harzes sind denjenigen .des im Hauptpatent beschriebenen identisch. <I>Beispiel 1:</I> 144 Teile a-Naphthöl werden geschmolzen und mit einem, Gemisch von<B>135</B> Teilen Sahwefelchlorür und 240 Teilen Benzoyl- @chlorid langsam unter Rühren in Reaktion gebracht.
Nach beendeter Salzsäure-Entwick- dung werden die noch im Harz enthaltenen sauren Verunreinigungen durch Vakuum oder durch Waschen mit Wasser oder wässerigem Alkohol entfernt. Das feuchte Harz wird bei nicht zu hoher Temperatur getrocknet.
<I>Beispiel 2:</I> 140 Teile a-Naphthol werden mit 120 Tei len Natriumhydroxyd in 500 Teilen Wasser gelöst und unter sehr gutem Rühren mit einem Gemisch von 135 Teilen Schwefel- chlorür und 240 Teilen Benzoylchlorid all mählich versetzt, so dass das Reaktions gemisch nicht ins Sieden gerät. Das abge schiedene Kochsalz, sowie Spuren von benzoe- saurem Natron werden durch Waschen mit Wasser, Wasseralkohol und Alkohol ent fernt.
Die Waschung mit Alkohol wird so lange fortgesetzt, bis kein unverestertes Harz als Verunreinigung sich nachweisen lässt. Hierauf wird das Harz bei mässigen Tempera turen getrocknet.
Process for the preparation of a resin which can be used as protective and insulating varnish, impregnation agent, adhesive and the like.
According to additional patent no. 104247, a resin that can be used as a protective and insulating varnish, impregnation agent, adhesive and the like can be obtained by treating the resin obtained by sulphurising α-naphthol with benzoylating agents.
It has now been found that it is not necessary to start from the finished alkali and alcohol-soluble sulfur resin and convert the same into the ester resin by benzoylation, but that it is possible to carry out the resinification process and the esterification in one operation by doing the a naphthol serving as the starting material of the sulfur resin mentioned, optionally in the presence of water,
aqueous alkalis or other solvents or diluents simultaneously with sulfur halides and benzoylating agents respectively. . treated with mixtures of both.
The resin obtained in this way is purified as indicated in the main patent. The properties of this resin are identical to those described in the main patent. <I> Example 1: </I> 144 parts of α-naphthoil are melted and slowly reacted with a mixture of <B> 135 </B> parts of sulfur chloride and 240 parts of benzoyl chloride while stirring.
After the development of hydrochloric acid has ended, the acidic impurities still contained in the resin are removed by vacuum or by washing with water or aqueous alcohol. The moist resin is dried at a temperature that is not too high.
<I> Example 2: </I> 140 parts of a-naphthol are dissolved with 120 parts of sodium hydroxide in 500 parts of water and a mixture of 135 parts of chlorine sulfur and 240 parts of benzoyl chloride are gradually added with very good stirring, so that the reaction mixture does not boil. The separated table salt and traces of benzoic acid soda are removed by washing with water, water alcohol and alcohol.
The washing with alcohol is continued until no unesterified resin can be detected as an impurity. The resin is then dried at moderate temperatures.
