Description

Verfahren zur Herstellung von Kondensationsprodukten Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Kondensationsprodukten, das darin besteht, daß man saure Naturharze oder deren Ester in Gegen wart von Borfluorid oder -komplexen Fluoroborsäuren auf Phenolester einwirken läßt und die erhaltenen Verbindungen gegebenenfalls einer Nachbehandlung mit Aldehyden unterwirft.Process for the production of condensation products Invention is a process for the preparation of condensation products that is contained therein consists that you can acidic natural resins or their esters in the presence of boron fluoride or -complexes fluoroboric acids can act on phenol esters and the obtained Compounds optionally subjected to an aftertreatment with aldehydes.

Die neuen Reaktionsprodukte unterscheiden sich von den Ausgangsstoffen vor allem durch eine stark herabgesetzte Jodzahl sowie meist durch einen erhöhten Erweichungspunkt; außerdem sind sie frei von den für Naturharze charakteristischen Farbreaktionen mit konzentrierter Schwefelsäure und Essigsäureanhydrid.The new reaction products differ from the starting materials mainly due to a greatly reduced iodine number and usually an increased one Softening point; in addition, they are free from those characteristic of natural resins Color reactions with concentrated sulfuric acid and acetic anhydride.

Als Kondensationsmittel eignen sich außer Borfluorid auch komplexe Fluoroborsäuren, wie z. B. Foi:miatotrifluoroborsäure, Laktatofluoroborsäure.In addition to boron fluoride, complexes are also suitable as condensing agents Fluoroboric acids, such as. B. Foi: miatotrifluoroboric acid, lactatofluoroboric acid.

Beispiel i i 8 Gewichtsteile Borfluorid werden im Verlauf von 6 Stunden bei 7o bis So' C in eine Mischung von 3oo Gewichtsteilen Kolophonium (Säurezahl i6;, Jodzahl 130, Erweichungspunkt 7o°), i 5o Gewichtsteilen o-Kresolacetat und i oo Gewichtsteilen Benzol eingeleitet. Nach 14stündigem Stehen bei Zimmertemperatur löst man das dickflüssige, braune Reaktionsprodukt in zoo Gewichtsteilen Benzol und gibt 34 Gewichtsteile Natriumcarbonat zu. Nach dem Abfiltrieren des Niederschlages werden die flüchtigen Anteile unter vermindertem Druck abdestilliert, wobei als Rückstand 33 i Gewichtsteile eines hellen, klaren Harzes erhalten werden. Dieses zeigt folgende Kennzahlen: Säurezahl 4i, Jodzahl 8z, Erweichungspunkt io6. Beispiel z I In eine Mischung von 3oo Gewichtsteilen Kolophonium, i oo Gewichtsteilen Benzol und ibo Gewichtsteilen Dikresylcarbonat werden bei 8o° unter Rühren innerhalb 8 Stunden z4 Gewichtsteile Borfluorid eingeleitet. `ach i 2stündigem Stehen wird die braune Reaktionsmasse mit zoo Gewichtsteilen Benzol verdünnt und mit 46 Gewichtsteilen Natriumcarbonat neütralis%ert. Nach dem Abfzltrieren des Bodenkörpers und dem Abdestillieren der flüchtigen Bestandteile erhält man 334 Gewichtsteile eines klaren Harzes mit folgenden Kennzahlen: Säurezahl 42, Erweichungspunkt 98.Example i i 8 parts by weight of boron fluoride are added in the course of 6 hours at 70 to 50 ° C in a mixture of 300 parts by weight of rosin (acid number i6; iodine number 130, softening point 70 °), i 50 parts by weight of o-cresol acetate and i oo parts by weight of benzene initiated. After standing for 14 hours at room temperature the thick, brown reaction product is dissolved in zoo parts by weight of benzene and add 34 parts by weight of sodium carbonate. After filtering off the precipitate the volatile components are distilled off under reduced pressure, as Residue 33 parts by weight of a pale, clear resin are obtained. This shows the following key figures: acid number 4i, iodine number 8z, softening point io6. example In a mixture of 300 parts by weight of rosin, 100 parts by weight of benzene and ibo parts by weight of dicresyl carbonate are stirred at 8o ° within 8 Hours initiated z4 parts by weight of boron fluoride. After standing for 2 hours, the brown reaction mass diluted with zoo parts by weight of benzene and with 46 parts by weight sodium neutrally% ert. After removing the floor body and distilling off the volatile constituents, 334 parts by weight are obtained of a clear resin with the following parameters: acid number 42, softening point 98.

Beispiel 3 Verwendet man in Beispiel i statt Kolophonium 3oo Gewichtsteile Kolophonium-. glycerin.ester (Säurezahl 7,8, Erweichungspunkt 7 6 und Jodzahl i i9) und 25 Gewichtsteile Borfluorid, so erhält man unter sonst gleichen Versuchsbedingungen 33o Gewichtsteile ,eines hellen, klaren Harzes mit folgenden Kennzahlen: Säurezahl 8, Jodzahl 8 i, Erweichungspunkt 99.Example 3 In example i, 300 parts by weight are used instead of rosin Rosin-. glycerin.ester (acid number 7.8, softening point 76 and iodine number i i9) and 25 parts by weight of boron fluoride are obtained under otherwise identical test conditions 33o parts by weight, of a light, clear resin with the following key figures: acid number 8, iodine number 8 i, softening point 99.
