aus Harzsäuren.from resin acids.

Zusatz zum Patente 183185 vom 3. April 1904.Addendum to patent 183185 of April 3, 1904.

Patentiert im Deutschen Reiche vom 6. Oktober 1904 ab. Längste Dauer: 2. April 1919.Patented in the German Empire on October 6, 1904. Longest duration: April 2, 1919.

Gemäß Patent 183185 erhält man aus Kopaivabalsam und Formaldehyd feste Kondensationsprodukte. Die vorliegende Erfindung ist eine weitere Ausbildung dieses Verfahrens. Es besteht in der Herstellung von Kondensationsprodukten des Formaldehyds mit Harzsäuren beliebiger Art mit Ausnahme der Harzsäuren des Kopaivabalsams. Der Erfinder hat gefunden, daß, wenn man auf derartige Harzsäuren, beispielsweise Colophonium, Formaldehyd, in Gegenwart von Säuren, wie Salzsäure, Schwefelsäure, Ameisensäure, Essigsäure einwirken läßt, neue technisch oder medizinisch verwertbare Produkte entstehen.According to patent 183185, copaiva balsam is obtained and formaldehyde solid condensation products. The present invention is another embodiment of this method. It consists in the production of condensation products of formaldehyde with resin acids of any kind with the exception of the resin acids of the copaiva balsam. The inventor has found that when one looks at such resin acids, for example rosin, formaldehyde, in the presence of acids such as hydrochloric acid, Allow sulfuric acid, formic acid, acetic acid to act, creating new technically or medically usable products.

Beispiel I.Example I.

Man löst beispielsweise 1 kg Colophonium in 4 kg Alkohol auf, mischt mit 1 kg 4oprozentiger Formaldehydlösung und leitet SaIzsäure durch das Gemisch. Es scheidet sich alsdann, schneller bei gleichzeitiger Erwärmung, ein geruchloser, harziger Körper aus, welcher einen höheren Schmelzpunkt als das ursprünglich verwendete Colophonium und diesem gegenüber die weitere neue Eigenschaft besitzt, in rissefreien Schichten aus seinen Lösungen in flüchtigen Lösungsmitteln aufzutrocknen, ein für die Herstellung von Lacken in höchstem Grade bedeutsamer Faktor.For example, 1 kg of rosin is dissolved in 4 kg of alcohol and mixed with 1 kg of 4% strength Formaldehyde solution and conducts hydrochloric acid through the mixture. It then separates, faster with simultaneous warming, an odorless, resinous body, which has a higher melting point than that originally used rosin and compared to this the other new property possesses, in crack-free layers from its solutions in volatile solvents to dry up, one for making Lacquers are the most important factor.

Im folgenden wird ein Beispiel unter Verwendung von Ameisensäure gegeben:The following is an example using formic acid:

Beispiel II.Example II.

Man löst beispielsweise 300 g Mastix in 11 siedenden Alkohol auf, gibt hierzu 300 g Formaldehyd 4oprozentig und 600 g Ameisensäure. Die Mischung wird am Rücknußkühler mehrere Stunden im Sieden erhalten. Beim Eingießen in Wasser scheidet sich ein aromatisch riechender, weicher, harziger Körper ab, der, ausgewaschen, an der Luft allmählich hart wird.For example, dissolve 300 g of mastic in 11 boiling alcohol, add 300 g of 4% formaldehyde and 600 g of formic acid. The mixture is kept at the boil for several hours on the re-nut condenser. At the Poured into water, an aromatic, soft, resinous body is deposited which, washed out, gradually hardening in air.

Beispiel III.Example III.

Man löst 1 kg Colophonium in 4 kg Alkohol auf, mischt mit 1 kg 40prozentiger Formaldehydlösung und setzt 600 g konzentrierter Schwefelsäure langsam unter Kühlung zu. Das Gemisch läßt man stehen und gießt es nachher in Wasser. .Dissolve 1 kg of rosin in 4 kg of alcohol and mix with 1 kg of 40 percent formaldehyde solution and slowly adds 600 g of concentrated sulfuric acid with cooling. The mixture is left to stand and then poured in water. .
