Description

Verfahren zur Herstellung von Polykondensationsprodukten Im Patent goi 592 ist ein Verfahren zur Kündensation von Aminoasäuren 'bzw. von Diaminen und Dicarbonsäuren mit ausreichend langen Ketten zu Polyamiden beschrieben worden, welches dadurch gekennzeichnet ist, daß man die Ausgangsmaterialien in feiner Verteilung bzw. in dünnen Schichten höheren Temperaturen aussetzt oder die Schmelzen der genannten Ausgangsmateriahen in dünnen Schichten, vorzugsweise in fortlaufendem Arbeitsgang, über beheizte Flächen laufen läßt. Die Schmelzen können auch durch senkrecht stehende beheizte Rohre oder Türme, die mit großoberflächigem Material gefällt sind, von oben nach untien hindurchgeleitet oder auch durch heiße poröse Wändie oder Schichten gepneßtoder gesaugt werden. In allen. Fällten kann die Beheizung des Reaktionsraumes vermittels durchströmender heißer inerter Gase oder Dämpfe erfolgen, auch können Lösungen oder Schmelzen der Awsgangsmatieralien in heißen inerten Gasen oder Dämpfen zerstäubt zur Einwirkung gebracht werden.Process for the production of polycondensation products The patent goi 592 describes a process for the termination of amino acids' resp. of diamines and dicarboxylic acids with sufficiently long chains to form polyamides, which is characterized in that the starting materials are exposed to higher temperatures in fine distribution or in thin layers or the melts of the starting materials mentioned are overheated in thin layers, preferably in a continuous operation Runs surfaces. The melts can also be passed through vertical heated pipes or towers, which are precipitated with large-surface material, from top to bottom, or they can also be pressed or sucked through hot, porous walls or layers. In all. Precipitations can be used to heat the reaction space by means of hot inert gases or vapors flowing through them; solutions or melts of the starting materials in hot inert gases or vapors can also be atomized to act.

Es wurde nun gefunden, daß, diese Maßnahmen vorteilhaft auch auf die Herstellung anderer Polykondensationsprodukte aus anderen. bifwnktionellen organischen Verbindungen, die untrer Austritt von Wasser, Alkohol usw. verlaufen, übertragen werden können. Es können auf :diese Weise Polyamide, Polyharnsboffe, Polyunethame, Polyester und Mischkondensationspinodukte derselben hergestellt werden.It has now been found that these measures are also beneficial to the Manufacture of other polycondensation products from others. bifunctional organic Compounds that leak water, alcohol, etc., are transferred will can. In this way, polyamides, polyureas, Polyunethame, polyester and mixed condensation products of the same are produced.

Als Ausgangsmaterialien kommen alle an sich hierfür bekannten Substanzen in Frage, wie z. B. Dioarbonsäuren und deren funktionelle Derivate, wie Alkyl- und Arylester, Chloride, ferner Diamine, Glykole, Duretharne, Dih arn@stoffe sowie hhiifunktioryelle Verbindungen, welche zwei verschiedene solcher Gruppen besitzen, also etwa Amnosäuren, Amnoalkohole, Aminourethane, Aminoharustoffe, Urethancarbonsäuren, Harnsboffoarbonsäur:en, Oxysäuren, sowie die homologen Verbindungen, die an Stelle des. Sauerstoffs Schwefelenthalten, ferner z. B. die Harnstoffgruppa enthaltende Dica.rbonsäuren, die unter Aufspaltung der H.arnstoffgruppe und unter Austritt von Kohlendioxyd und Wasser mit sich selbst zu Polyamiden kondensieren.All substances known per se for this are used as starting materials in question, such as B. dioarboxylic acids and their functional derivatives, such as alkyl and Aryl esters, chlorides, also diamines, glycols, Duretharne, Dih arn @ stoffe and hhiifunktioryelle Compounds that have two different such groups, such as amino acids, Amno alcohols, aminourethanes, amino ureas, urethane carboxylic acids, uric acid carboxylic acids, Oxy acids, as well as the homologous compounds which contain sulfur instead of oxygen, further z. B. the urea group containing dicarboxylic acids, with splitting of the urea group and with the escape of carbon dioxide and water with itself condense to polyamides.

Die Vorteile des vorliegenden Verfahrens sind insbesondere in der ganz wesentlichen Beschleunigung der Reaktion, mithin. also in einer bedeutenden Abkürzung der Reaktionszeit, zu erblicken. Beispielsweise lassen sich die sonst üblichen Reaktionsseiten vorn etwa i1/2 his a1/2 Stunden aufwärts bis unter Umständen 6 bis 8 Stunden auf 5 bis 15 Minuten und noch weniger abkürzen.The advantages of the present process are, in particular, the very substantial acceleration of the reaction. thus to be seen in a significant shortening of the reaction time. For example, the otherwise usual reaction pages can be shortened at the front from about 1/2 to 1/2 hours up to possibly 6 to 8 hours to 5 to 15 minutes and even less.

Au-s f ührungsbei s p iel i Mol Tetramethylenäiurethylan und i Mol Sebacinsäure werden gut gemischt und in feiner Aufteilung bzw. in dünner Schicht 5 bis 6 Minuten auf etwa z 5o bis 300° erhitzt. Man erhält ein Polyamid mit einer F,igenviskosität von i, 12.Example of one mole of tetramethylene acid ethylane and one mole Sebacic acid are mixed well and in fine division or in a thin layer Heated for 5 to 6 minutes to about z 50 to 300 °. A polyamide is obtained with a F, intrinsic viscosity of i, 12.
