Description

Verfahren zur Herstellung von Kunstmassen Im Patent 487 654 ist ein Verfahren zur Herstellung von Kunstmassen beschrieben, dadurch gekennzeichnet, daß man aromatische Amine oder deren Salze mit Formaldehyd in (mineral-) saurem Medium bis zur Bildung fester Gallerten reagieren läßt, letztere hernach mit solchen Mitteln behandelt, welche geeignet sind, die Wirkung der Säure aufzuheben, und die erhaltenen Produkte trocknet.Process for the production of synthetic masses In the patent 487,654 is a Process for the production of synthetic compositions described, characterized in that aromatic amines or their salts with formaldehyde in (mineral) acidic medium lets react until solid jelly is formed, the latter afterwards with such means treated, which are suitable to neutralize the effect of the acid, and the obtained Products dries.

Als Stoffe, welche dem Zweck der Aufhebung der Wirkung der Säure dienen sollen, sind in obigem Patent u. a. anorganische oder organische Basen oder basische Salze angegeben worden.As substances which serve the purpose of neutralizing the effect of the acid are in the above patent inter alia. inorganic or organic bases or basic Salts have been specified.

Es wurde nun gefunden, daß diese Nachbehandlung abgekürzt oder ganz weggelassen werden kann, wenn der Kondensationsmischung von Anfang an bzw. vor Bildung der Gallerte wasser- oder alkohollösliche Salze, wie z. B. Natriumchlorid, Ammoniumchlorid, Calciumchlorid, Ammoniumnitrat, Natriumsulfat, Magnesiumsulfat, Natriumlaktat u. dgl., zugefügt werden. Beispiel ro Teile Anilin werden mit xo Teilen Salzsäure und 15 Teilen Wasser, worin 2 Teile eines Salzes, wie z. B. Natriumchlorid, Ammoniumchlorid, Calciumchlorid, Ammoniumnitrat usw., gelöst sind, gemischt, worauf die Lösung mit 15 Teilen 4o °/9iger Formaldehydlösung kondensiert wird. Die Reaktion verläuft wie üblich. Die erhaltene rote Gallerte wird mit kaltem, dann mit heißem Wasser gewaschen, wobei dieselben, fast weißen horn- bzw. knochenartigen Produkte erhalten werden, wie sie in dem Patent 487 654 beschrieben sind.It has now been found that this aftertreatment can be shortened or entirely can be omitted if the condensation mixture is started from the start or before formation the jelly water- or alcohol-soluble salts, such as. B. sodium chloride, ammonium chloride, Calcium chloride, ammonium nitrate, sodium sulfate, magnesium sulfate, sodium lactate and the like Like., are added. Example ro parts of aniline are mixed with xo parts of hydrochloric acid and 15 parts of water, wherein 2 parts of a salt, such as. B. sodium chloride, ammonium chloride, Calcium chloride, ammonium nitrate, etc., are dissolved, mixed, followed by the solution with 15 parts of 4o% formaldehyde solution is condensed. The reaction goes like this common. The resulting red jelly is washed with cold, then with hot water, the same, almost white horn-like or bone-like products being obtained, as described in patent 487,654.
