Description
Verfahren zur Erhöhung des Schmelzpunktes von Novolaken und den daraus mit natürlichen Harzsäuren bereiteten öllöslichen Verbindungen Es wurde gefunden, daß der Schmelzpunkt von Novolaken durch Erhitzen dieser Harze bei 22j bis 300° mit geringen Mengen von Borsäureanhydrid heraufgesetzt werden kann. Dabei sind unter Novolaken die bekannten Kondensationsprodukte aus Phenol bzw. Kresol mit Aldehyden, insbesondere Formaldehyd, zu verstehen, die infolge ihrer Herstellungsweise die Eigenschaft besitzen, dauernd schmelzbar zu bleiben.Process for increasing the melting point of novolaks and those from them Oil-soluble compounds prepared with natural resin acids It has been found that the melting point of novolaks by heating these resins at 22j to 300 ° can be increased with small amounts of boric anhydride. Thereby are under Novolaks the well-known condensation products of phenol or cresol with aldehydes, in particular formaldehyde, to understand which, as a result of their production method, the Have the property of remaining permanently fusible.
Dieser wertvolle technische Effekt ist aber nicht nur auf die Novolake allein beschränkt, sondern kommt erst dann zur vollen Geltung, wenn man Esterharze in geeigneter Weise mit dem Borsäureanhydrid zur Reaktion bringt. Unter diesen Esterharzen sind diejenigen Verbindungen zu verstehen, die man in öllöslicher Form .durch längeres Erhitzen von \Tovolaken mit Harzsäuren, insbesondere mit Kolophonium, erhält. Diese Produkte weisen sonst durchschnittlich, wenn sie bei 25o bis 300° bereitet werden, einen Schmelzpunkt von nur 8o bis go° auf.This valuable technical effect is not only due to the novolak only limited, but only comes into its own when you use ester resins reacts with the boric anhydride in a suitable manner. Among these ester resins those compounds are to be understood, which one in oil-soluble form .by longer Heating \ tovolaks with resin acids, especially rosin, is preserved. These Otherwise, products show average, if they are prepared at 25o to 300 °, a melting point of only 8o to go °.
Die Reaktion dieser Körper mit dem Borsäureanhydrid kann auf zweierlei Art stattfinden. Entweder trägt man eine geeignete Menge von Borsäureanhydrid (o,5 bis 6 °/a) in die heiße flüssige Schmelze des Novolaks oder des Esterharzes ein und erhitzt nun kurze Zeit, etwa 3o bis 6o Minuten, auf 25o bis 300°, oder man bringt gleich ein Gemisch der Ausgangsstoffe, also Novolak, Kolophonium und Borsäureanhydrid, in genügend zerkleinerter Form bei 25o bis 300° zur Reaktion. Diese letztere Arbeitsweise ist der ersteren vorzuziehen, weil infolge der besseren Durchmischung die Wirkung der Borsäure mehr zur Geltung kommt.The reaction of this body with the boric anhydride can go in two ways Kind of take place. Either you carry a suitable amount of boric anhydride (0.5 up to 6 ° / a) into the hot liquid melt of the novolak or the ester resin and now heat for a short time, about 30 to 60 minutes, to 25o to 300 °, or one brings a mixture of the starting materials, i.e. novolak, rosin and boric anhydride, in sufficiently crushed form at 25o to 300 ° for reaction. This latter way of working is preferable to the former because the effect is due to the better mixing boric acid comes into its own.
Während des Erhitzens verflüchtigt sich die Borsäure größtenteils aus dem Reaktionsgemisch und setzt sich an den kälteren Stellen des Reaktionsgefäßes wieder an. Die Dauer des Erhitzens schwankt bei der Bereitung eines gehärteten Esterharzes zwischen 6 und 16 Stunden, je nachdem man die Löslichkeitsverhältnisse des Esterharzes beeinflussen will, die bei längerem Erhitzen sich verbessern. Geht man dagegen vom fertigen Esterharz bzw. vom Novolak allein aus, so genügt durchschnittlich bereits eine 1@2 Stunde bis r Stunde Erhitzung, um den gewünschten Effekt der Schmelzpunkterhöhung hervorzurufen.Most of the boric acid evaporates during heating from the reaction mixture and settles in the colder parts of the reaction vessel back to. The duration of the heating varies in the preparation of a cured ester resin between 6 and 16 hours, depending on the solubility ratios of the ester resin want to influence, which improve with prolonged heating. On the other hand, if you go from made from ester resin or from novolak alone, on average it is sufficient a 1 @ 2 hour to r hour heating to get the desired effect of melting point elevation to evoke.
Beispiel z Ein sauer kondensiertes Phenol- oder Kresolformaldehydharz mit einem Schmelzpunkt von 115' wird mit o,6"/, Borsäureanhydrid, beide Stoffe in fein gepulverter Form und innig verrieben, z Stunde auf 225° erhitzt. Der Schmelzpunkt des Novolaks ist um zo° gestiegen. Mit 5 °/o Borsäure verrieben und auf 225° erhitzt, wird der Schmelzpunkt um mehr als 2o° heraufgesetzt. Beispiele Ein aus 2 Teilen Novolak und 5-Teilen Kolophonium hergestelltes öllösliches Esterharz, das einen Schmelzpunkt von 9o° besitzt, wird mit 5 °/o Borsäureanhydrid 30 Minuten auf etwa 25o bis 265° erhitzt. Der Schmelzpunkt ist nach dieser Behandlung auf r23° gestiegen. Eine- Änderung in den Löslichkeitsverhältnissen ist nicht eingetreten.Example z An acidic condensed phenol or cresol-formaldehyde resin with a melting point of 115 'is thoroughly triturated with 0.6 "/, boric anhydride, both substances in finely powdered form, heated to 225 ° for an hour. The melting point of the novolak is zo ° Triturated with 5% boric acid and heated to 225 °, the melting point is increased by more than 20 ° 5 % boric anhydride was heated for 30 minutes to about 25 ° to 265 ° C. After this treatment, the melting point rose to about 23 ° C. There was no change in the solubility ratios.
Beispiel 3 Ein aus 2 Teilen Novolak, 5 Teilen Kolophonium und o,35 Teilen Borsäureanhydrid bestehendes Gemisch wird 16 Stunden auf 25o bis 265° erhitzt. Der Schmelzpunkt des entstehenden öllöslichen Harzes beträgt i28°. In einem Blindversuch wurden die Komponenten ohne das Borsäureanhydrid für sich allein 16 Stunden auf 25o bis 265° erhitzt. Der Schmelzpunkt des entstehenden öllöslichen Harzes betrug dann nur 790.Example 3 A made from 2 parts of novolak, 5 parts of rosin and o.35 Parts of boric anhydride existing mixture is heated to 25o to 265 ° for 16 hours. The melting point of the resulting oil-soluble resin is i28 °. In a blind experiment the components without the boric anhydride were on for 16 hours on their own Heated between 25o and 265 °. The melting point of the resulting oil-soluble resin was then only 790.
