Description

Verfahren zur Darstellung von barzartigen Kondensationsprodukten aus Phenolderivaten und Aldehyden Die bisher bekannt gewordenen harzartigen Kondensationsprodukte aus Phenolen und Aldehyden besitzen alle zwei wesentliche 'Nachteile, die ihre Einführung in die Technik erschweren. Es sind dies erstens die geringe Lichtechtheit ihrer Lackanstriche und Poli- turen, zweitens der ihnen mehr oder weniger stark anhaftende, nie ganz zu vermeidende Phenolgeruch. Es wurde nun gefunden, daß man durch Be- handeln von Dioxydiarylsulfonen mit Al- dehyden oder aldehydabspaltenden 1\Etteln in Gegenwart katalytisch wirkender Stoffe, wie z. B. Chlorwasserstoffsäure, harzartige Pro- dukte erhält, welche die obengenannten schlechten Eigenschaften nicht besitzen. Sie zeichnen sieh durch Lichtechtheit und son- stige gute Harzeigenschaften aus, so daß sie einen wertvollen Ersatz für die besten Natur- harze, wie Schellack und Kopal, bilden. Sie lassen sich mit Erfolg mit Naturharzen selbst, z. B. mit Kolophonium, vereinigen. Die überführung - von Dioxydiarylsulfoneii in harzartige Kondensationsprodukte durch Elinwirkung von Aldehyd ist von technischer Bedeutung, indem dadurch die Lichtechtheit der hergestellten Harze in hervorragender Weise verbessert wird, während bisher be- kannte Phenolaldehydbarze schon nach kurzer Zeit, sofern sie dem Licht ausgesetzt sind, eine erhebliche Verfärbung erleiden. Ferner sind sie vollkommen geruchlos. Die beson- dere, mit den Dioxydiary1sulfonen erreichte Wirkung war in keiner Weise vorauszusehen, namentlicb deswe07en, weil die so erhaltenen Produkte auch den nach dem Verfahren der österreichischen Patentschrift 65 893 erhält- licben bedeutend überlegen sind. B e i s p i el e. 1. I25Teilepl.,p,-Dioxydiphenylsulfon(v,-,1. Ann. 172, S. 36, Ber. 9 [18, 61, S. 1149')' werden mit ioo Teilen Wasser und 6- Teilen Formaldebyd (3oprozentig) vermischt, der Mischung noch 3o Teile Eisessig zugesetzt, unter Rückflußkühlung gekocht und langsam 15 Teile konzentrierte Salzsäure hinzugefügt. Die -Masse wird etwa 5 Stunden im Sieden ge- halten. bzw. so lange, bis nur noch Spuren Formaldehyd nachweisbar sind. Das über dem entstandenen Harz stehende Wasser wird abgegossen und die flüchtigen Bestandteile durch Vakuumdestillation entfernt. Nach Er- kalten hinterbleibt ein hellgelb bis rötlichgelb gefärbtes Harz von sehr hohem Klebepunkt, das vollkommen frei ist von irgendeinem stö- renden Geruch. Es lößt sich sehr leicht in Alkohol, Aceton, Alkalien, nicht in Denzol, Terpentinöl und Leinöl. Der mit ihm herge- stellte Lack ist von auffallender Lichtechtheit. --. i 5o Gewichtsteile p, p'-Dioxydikresylsul- fon, erhalten aus m-Kresol (in ähnlicher Weise wie das in Beispiel i genannte Sulfon), werden mit 5oo Teilen Wasser und Mit 7oGe-wichtsteilen-konzentrierter Natronlauge vermischt, so daß vollkommene Lösung des Sulfons in der Kälte eintritt. Der Lösung werden 5oTeile Formaldehyd (3oprozentig) zugefügt und die Lösung mehrere Tage (etwa vier Tage) stehengelassen. Dann wird unter gutem Durchrühren so viel verdünnte Salzsäure zugegeben, wie der angewandten Menge Alkali entspricht oder ein sehr geringer Überschuß. Das entstandeneHarz fällt als körnige Masse aus. Sie wird abgesaugt, gut ausgewaschenundgetrocknet. Man erhält ein geruchloses, hellrötlich gefärbtesHarzpulver, welches sich glatt inAlkohol und in Alkalien löst. Man erhält mit ihm Polituren von sehr hoher Lichtechtheit und gutem Glanz. 'Man kann natürlich beim Polieren bekannte porenfüllende und glanzerhöhende Mittel zusetzen, wie Wachs, Celluloseester usw.Process for the preparation of bar-like condensation products from phenol derivatives and aldehydes The resinous ones known so far Condensation products from phenols and Aldehydes all have two major ones 'Disadvantages of their introduction to technology make more difficult. First of all, these are the minor ones Lightfastness of your paint coats and poli- tures, secondly, of them more or less strongly adherent, never entirely avoidable Phenol odor. It has now been found that by loading deal with Dioxydiarylsulfonen with Al- dehydrating or aldehyde-releasing 1 \ Etteln in Presence of catalytically active substances, such as z. B. hydrochloric acid, resinous products products containing the above do not have bad qualities. she distinguish you through lightfastness and always have good resin properties so that they a valuable substitute for the best natural form resins such as shellac and copal. she can be successfully used with natural resins themselves, z. B. with rosin, combine. The transfer - from Dioxydiarylsulfoneii into resinous condensation products The action of aldehyde is more technical Significance by thereby ensuring the lightfastness of the resins produced in excellent Way is improved, while previously knew phenol aldehyde after a short time Time, provided they are exposed to light, suffer significant discoloration. Further they are completely odorless. The special which reached with the dioxydiary sulfones Effect could not be foreseen in any way, Namely deswe07en because the so received Products also made after the process of Austrian patent specification 65 893 received- licben are significantly superior. Example p i el e. 1. I25Partepl., P, -Dioxydiphenylsulfon (v, -, 1. Ann. 172, p. 36, Ber. 9 [18, 61, p. 1149 ')' are with 100 parts water and 6 parts Formaldebyd (3%) mixed, the 3o parts of glacial acetic acid added to the mixture, refluxed and slowly 1 5 parts of concentrated hydrochloric acid were added. The mass is boiled for about 5 hours. keep. or until there are only traces left Formaldehyde are detectable. The above the resulting resin becomes stagnant water poured off and the volatile components removed by vacuum distillation. After he- cold leaves a light yellow to reddish yellow colored resin with a very high adhesive point, that is completely free from any odor. It dissolves in very easily Alcohol, acetone, alkalis, not in denzene, Turpentine oil and linseed oil. Who came with him The paint is strikingly lightfast. -. i 50 parts by weight of p, p'-Dioxydikresylsul- fon, obtained from m-cresol (in a similar Like the sulfone mentioned in Example i), are mixed with 500 parts of water and 7o parts by weight of concentrated sodium hydroxide solution, so that the sulfone is completely dissolved in the cold. 50 parts of formaldehyde (3%) are added to the solution and the solution is left to stand for several days (about four days). Then, with thorough stirring, add as much dilute hydrochloric acid as corresponds to the amount of alkali used or a very small excess. The resulting resin precipitates as a granular mass. It is vacuumed, washed well and dried. An odorless, light reddish colored resin powder is obtained, which dissolves smoothly in alcohol and in alkalis. It is used to obtain polishes of very high lightfastness and good gloss. 'You can of course add pore-filling and gloss-increasing agents to polishing, such as wax, cellulose esters, etc.
