Es wurde gefunden, dass sich feste, harte, glänzende Kunstmassen bilden, wenn Funanearbonsäure (Brenzschleimsäure) bei Anwesenheit von Phenolen oder von Ölen, die Phenol, Kresol oder ähnliche Stoffe enthalten, unter Druck mit konzentrierter Schwefelsäure, Salzsäure, Phosphorsäure oder ihren Mischungen erhitzt wird. Die erhaltenen Massen stellen einen Hartgummiersatz dar und sind sehr widerstandsfähig gegen alkalische Lösungen. Durch Zusatz von Formaldehyd oder dessen Polymeri- sations-oder Kondensationsprodukten kann man den Prozess verbessern und die Produkte noch veredeln.

EMI1.1
It has been found that solid, hard, shiny synthetic materials are formed when funanearboxylic acid (pyrocic acid) is heated under pressure with concentrated sulfuric acid, hydrochloric acid, phosphoric acid or their mixtures in the presence of phenols or oils containing phenol, cresol or similar substances . The masses obtained represent a hard rubber substitute and are very resistant to alkaline solutions. The process can be improved and the products can be refined by adding formaldehyde or its polymerization or condensation products.
Example 1: 100 parts of furancarboxylic acid and: ') 0 parts of crystallized phenol are treated with hydrochloric acid
EMI1.2
heats. With brief heating and low pressure, a liquid condensation product is obtained, which can be used for the impregnation of various filling compounds and can then be fixed by subsequent heating. Solid masses are obtained through longer and higher heating. The free acid in the masses obtained can either be acid-binding by adding lime or the like
EMI1.3
Quantities can be changed in both directions.
Example 2: 100 parts of furancarboxylic acid and 100 parts of acid tar oil and 20 to 30 parts of paraformaldehyde are condensed as in Example 1 in the presence of hydrochloric acid gas and 5 parts of phosphoric acid. A more or less solid mass forms, which after removal does not condense.
EMI1.4
ider can be pressed into objects with any filler. With shorter heating or lower pressure, semi-liquid products can be obtained which, as indicated in Example 1, can be used very well especially for impregnation purposes.
These substances are also used in the production of paints that are soluble in alcohol, acetone and, in some cases, in benzene. suitable.
