Description
Verfahren zur Herstelltineines liarzartigeu Stoffes. Bekanntlich entstehen durch Kondeiis.Ltioii von Phenolen mit Aldehyden, insbesondere Formaldehyd, in alkalischer, saurer oder neu traler Lösung Produkte, die harzartigen t'lia- rakter haben.
Die älteren dieser Verfahren liefern in der Regel übelriechende, durch Wirkung voll Luft und Licht nachdunkelnde und morsch und bröcklig werdende Körper. Dieselben Veränderungen erleiden naturgemäss auch die daraus hergestellten Lackanstriche und Poli turen.
Die neueren Verfahren, welche diese -Übel stände beseitigen wollen, erfordern entweder besonders reines Ausgangsmaterial, wie es in den technischen Phenolgeniischen nicht geboten wird, oder grössere Mengen saurer. entweder gar nicht oder nur auf umständlichem Wege regenerierbarer Kondensationsmittel.
Sie liefern ferner sämtlich entweder alkali- lösliehe, oder in den üblichen für Lacke in Betracht kommenden Lösungsmitteln nur schi- schwer lösliche Produkte.
f:s hat sich nun gezeigt, dass das Konden- sationsprodukt aus technischem Kresol und Formaldehyd in einen neuen, völlig neutralen, in Benzol. llzetoii usw. leicht licsliclieii, sehr harten, spr;;den, hochschmelzenden, Hellgelben, durchsichtigen;
an Licht und Luft unveränder- lichen Körper von Harzhabitus übergeführt wird, wenn es vorteilhaft in alkalischer Lösung mit p-Toluolsulfoclilorid behandelt wird.
Beispiel <I>I:</I> 100 g des nach einer der bekannten Methoden lierge@st < llten ]ii-esolallsoliols raus technischem Kresolgeinisch)
werden in einem geringen @rberscliufi verdünnter Natronlauge gelöst und bei einer Temperatur rieht über 30 nüt einer Lösung von 137 g p-Toluol- su@f@ch@orid in :
500 g Benzol mehrere Stunden gerührt. Die Benzolsehicht, die das Produkt enthält, wird von eventuell anhaftender Lauge gewaschen. getrocknet lind das Benzol ab getrieben.
Das zurückgebliebene Hellgelbe, harte Produkt ist in jeder Beziehung den natürlichen Harzen. wie Kolial usw., ähnlich. <I>Beispiel</I> Ir 100 g Formalinkondensationsprodukt, leer gestellt aus der Fraktion 215-220" des technischen Kresols (also im wesentlichen aus den Xy lenolen 1:2':4, 1:3:4 und<U>1:4:
2</U> bestehend), werden in einen geringen L'ber- schufi verdiinnter Natronlauge gelöst und bei einer Temperatur nicht über 30 mit einer Lösung von<B>137</B> g p-Toluolsulfochlorid in 500 g Benzol mehrere Stunden gerührt.
Die Weiterverarbeitung erfolgt dann wie in Beispiel I, das entstandene Produkt hat genau die gleichen Eigenschaften wie das nach Beispiel I erhaltene.
Process for the manufacture of a resin-like substance. It is well known that the condensation of phenols with aldehydes, in particular formaldehyde, in alkaline, acidic or neutral solutions gives rise to products that are resinous in character.
The older of these methods usually produce foul-smelling bodies, which darken after exposure to air and light, and which become rotten and crumbly. The same changes naturally also suffer from the lacquer coatings and polishes produced from them.
The newer processes, which want to eliminate these -Übel stands, either require particularly pure starting material, as it is not offered in the technical phenol geniic, or larger amounts of acidic. condensation agents that cannot be regenerated at all or only in a cumbersome way.
Furthermore, they all provide products that are either alkali-soluble or only sparingly soluble in the usual solvents used for paints.
f: s has now been shown that the condensation product of technical cresol and formaldehyde is transformed into a new, completely neutral one, benzene. llzetoii etc. slightly licsliclieii, very hard, brittle; den, high-melting, light yellow, transparent;
A body which is unchangeable in light and air is converted from resinous habit when it is advantageously treated in an alkaline solution with p-toluenesulfocliloride.
Example <I> I: </I> 100 g of lierge @ st <llten] ii-esolalloliols according to one of the known methods out of technical cresolgine)
are dissolved in a small amount of dilute sodium hydroxide solution and at a temperature of over 30 minutes, a solution of 137 g of p-toluene-su @ f @ ch @ orid in:
500 g of benzene stirred for several hours. The benzene layer containing the product is washed from any lye that may have adhered. dried and driven off the benzene.
The remaining pale yellow, hard product is in every respect natural resins. like colial etc., similar. <I> Example </I> Ir 100 g formalin condensation product, left blank from fraction 215-220 "of technical cresol (i.e. essentially from the xylenes 1: 2 ': 4, 1: 3: 4 and <U> 1 : 4:
2), are dissolved in a small amount of diluted sodium hydroxide solution and stirred for several hours at a temperature not exceeding 30 with a solution of 137 g of p-toluenesulfonyl chloride in 500 g of benzene .
The further processing then takes place as in example I, the resulting product has exactly the same properties as that obtained according to example I.
