Patentiert im Deutschen Reiche vom 5. Februar 1907 ab. Patented in the German Empire on February 5 , 1907.
Durch Kondensation von Phenolen mit Formaldehyd unter Anwendung von neutralen oder alkalisch reagierenden Salzen als Kondensationsmittel können harzartige Produkte erhalten werden, die sich in den gebräuchlichen organischen Lösungsmitteln, wie Alkohol, Aceton usw., lösen und als Ersatzmittel der natürlichen Harze bei der Herstellung von Lacken, Polituren usw. Verwendung finden können. Es brat sich nunBy condensation of phenols with formaldehyde using neutral or Alkaline salts as condensation agents can result in resin-like products which are found in common organic solvents such as alcohol, acetone, etc., and as a substitute for natural resins in the manufacture of paints, polishes, etc. Can be used. It is now frying
ίο gezeigt, daß man aus Phenolen und Formaldehyd unter Anwendung von neutralen oder alkalisch reagierenden Salzen als Kondensationsmittel auch in allen gebräuchlichen Lösungsmitteln ganz unlösliche und auch unschmelzbare Produkte erhalten kann. Diese entstehen, wenn die Kondensation zwischen Phenolen und Formaldelvyd in Gegenwart von mehr Formaldehyd oder von mehr kondensierend wirkendem Salz oder von mehr Fonnaldehyd und Salz durchgeführt wird, als zur Bildung der löslichen harzartigen Produkte erforderlich ist. Als Kondensationsmittel kommen unter anderem neutrale oder alkalisch reagierende Salze, wie Kaliumchromat, neutrales Natriumsulfit, Ammoniumsulfit, Natriumthiosulfat, Trinatriumphosphat, Natriumbicarbonat, Natrium-, Kalium- und Ammoniumcarbonat oder Natriumacetat, zur Anwendung.ίο shown that one can make phenols and formaldehyde using neutral or alkaline salts as condensation agents, also in all common solvents can obtain completely insoluble and also infusible products. These arise when the condensation between phenols and Formaldehyde in the presence of more formaldehyde or of more condensing Salt or more formaldehyde and salt is carried out than to form the soluble resinous products is required. The condensing agents include neutral or alkaline reacting salts such as potassium chromate, neutral sodium sulfite, Ammonium sulfite, sodium thiosulfate, trisodium phosphate, sodium bicarbonate, sodium, Potassium and ammonium carbonate or sodium acetate, for use.
100 Teile Phenol werden mit 100 Teilen 40 prozentiger Formaldehydlösung und 30 Teilen neutralem Natriumsulfit in einem offenen Gefäß bei Wasserbadtemperatur erhitzt. Sowie eine Verdickung der hellgelben Masse eintritt, wird die Temperatur langsam bis auf etwa 130 ° C. gesteigert, wobei das Ganze zu einer harten glasigen Masse erstarrt, welche die Form des einschließenden Gefäßes hat, aus dem sie leicht zu entfernen ist. Die Masse ist unlöslieh und unschmelzbar, läßt sich auf der Drehbank bearbeiten, schleifen, polieren und mit Farbstoffen anfärben.100 parts of phenol are mixed with 100 parts 40 percent formaldehyde solution and 30 parts of neutral sodium sulfite in an open Vessel heated to water bath temperature. As soon as a thickening of the light yellow mass occurs, the temperature is slowly increased to about 130 ° C., whereby the whole thing becomes one hard glassy mass solidifies, which has the shape of the enclosing vessel from which it is easy to remove. The mass is insoluble and infusible, can be turned on the lathe edit, grind, polish and color with dyes.
Mit Säuren als Kondensationsmittel sind bereits früher unlösliche Produkte aus Phenol und Formaldehyd erhalten worden (vgl. Liebigs Annalen, Bd. 263 [1891], S. 284); diese sind indes für gewerbliche Zwecke unbrauchbar bzw. minderwertig, weil sie blasig, spröde und undurchsichtig ausfallen. ■With acids as condensation agents are already earlier insoluble products from phenol and Formaldehyde has been obtained (cf. Liebigs Annalen, Vol. 263 [1891], p. 284); these are however, unusable or inferior for commercial purposes because they are blistered, brittle and opaque fail. ■
Den Reaktionsgemischen können vor, während und nach der Kondensation Kieselgur, Talk, Stärke, Kasein, Farbstoffe und andere Stoffe je nach den zu erzielenden Eigenschaften der Endprodukte zugefügt werden.Before, during and after the condensation, kieselguhr, Talc, starch, casein, dyes and other substances depending on the properties to be achieved of the end products are added.
Die nach vorliegendem Verfahren aus Phenolen und Formaldehyd erhaltenen unlöslichen Kondensationsprodukte eignen sich vorzüglich für kunstgewerbliche und elektrische Zwecke, z. B. für die Knopfindustrie und für andere Zwecke.The insoluble ones obtained from phenols and formaldehyde by the present process Condensation products are ideally suited for arts and crafts and electrical purposes, z. B. for the button industry and for other purposes.
