Description
Verfahren zur Herstellung von Fasern, Bändchen, Folien oder andern Flächengebilden aus stickstoffhaltigen Polykondensationsprodukten. Durch Kondensation von Diisocyanaten mit Glykolen entstehen hochmolekulare Poly- urethane, die bei genügend hohem Polymeri- sationsgrad als Ausgangsmaterial für ge formte Gebilde, z. B. Fasern, verwendbar sind. Verspinnbare Produkte dieser Art er hält man z. B. durch Umsetzen von Octa- methylendiisocyanat mit 1.4-Butandiol (franz. Patent Nr. 845917).
Ähnliche Produkte bilden sich, wenn man Diurethane, z. B. Hexamethylen-bis-carb- aminsäurediphenylester, mit Glykolen, z. B. Dekamethylenglykol, umsetzt (ital. Patent Nr. 382755).
Man hat auch schon Polyurethanverbin- dungeu hergestellt aus Komponenten, die neben den urethanbildenden Gruppen bereits Amidgruppen (mit der Carbonylgruppe an C gebundene Carbonamidgruppen, Harnstoff gruppen, Sulfonamidgruppen -NH-SO2-, Sulfamidgruppen -NH-SO2-NH-) in offener Kette oder in heterocyclischen Ringen enthalten (franz. Patent Nr. 879703).
Gegenstand der Erfindung ist ein Ver fahren zur Herstellung von Fasern, Bänd chen, Folien oder andern Flächengebilden aus stickstoffhaltigen Polykondensationspro dukten, das dadurch gekennzeichnet ist, dass man Kohlensäureverbindungen von Amino- alkoholen bezw. Aminomercaptanen mit an gesättigte C-Atome gebundenen Amino- und Hydroxyl- bezw. Sulfhydrylgruppen und mit mindestens vier kettenbildenden Atomen zwischen endständigem Aminostickstoff und Hydroxyl- bezw. Mercaptogruppe durch Er hitzen kondensiert und verformt.
Gegebenen falls kann in Gegenwart von Lösungs- oder Verdünnungsmitteln oder von Katalysatoren, die die Abspaltung von Ammoniak oder Al kohol begünstigen, insbesondere Stoffen von der Art der Umesterungskatalysatoren, z. B. Kaliumcarbonat, Magnesiumogyd, Magne- siummethylat, Halogenwasserstoff, Toluol- sulfosäure, Naphthalinsulfosäure, Campher- sulfosäure, Zinkchlorid, Zinn-2-chlorid, ge arbeitet werden.
Als Ausgangsstoffe für die Durchfüh rung des Verfahrens kommen in erster Linie Derivate von Aminoalkoholen, beispielsweise Carbamidsäureester-, Harnstoff- und O-Ester verbindungen von Aminoalkoholen, in Frage.
Es kommen nicht nur Derivate einfacher Amiuoalkohole, z. B. Derivate des 4-Amino- butanols, des 5-Aminopentanols, des 4-Amino- cyclohexanols, des 4-Aminobutylmercaptans (aus Benzoylaminobutylchlorid und Kalium sulfhydrat mit folgender Hydrolyse) in Be tracht, sondern auch kompliziertere Aminooxy- bezw. Aminomercaptoverbindungen, deren Kette durch Heteroatome oder Heterogruppen, wie O, S, SO2, unterbrochen sein können, z. B. Derivate des #-Aminobutyl-#'-oxypropyl- sulfids (aus Benzoyl-aminobutylmercaptan und 3-Brompropanol). Insbesondere sind auch solche Abkömmlinge von Aminooxy- bezw.
Aminomercaptoverbindungen eingeschlossen, deren Kette durch Amidgruppen, z. B. an Kohlenstoff gebundene Carbonamidgruppen, Harnstoffgruppen, Sulfonamidgruppen, Sulf- amidgruppen, unterbrochen ist. Diese Amid- gruppen können sowohl in offener Kette als auch in heterocyclischen, in die Kette ein gefügten Kernen oder in beiden zugleich enthalten sein (vergleiche franz. Patent Nr. 879703).
Eine Ausführungsform des Verfahrens besteht darin, dass man auf die Amino- alkohole oder deren Salze mit Halogenwasser stoffsäuren Phosgen einwirken lässt und dann die Zwischenprodukte zweckmässig in Gegen wart eines Verdünnungsmittels erhitzt, wobei die weitere Kondensation unter Abspaltung von Halogenwasserstoff vor sich geht. Es ist anzunehmen, dass sich bei den Salzen zu nächst Chlorameisensäureester bilden, worauf die Chloridgruppe mit dem durch Halogen wasserstoff abgesättigten Stickstoff unter Abspaltung von 2 Mol Halogenwasserstoff reagiert. Als Lösuugs- oder Verdünnungs mittel für die Reaktion eignen sich besonders Halogenkohlenwasserstoffe mit einem Siede punkt zwischen 110 und 170 C, z. B.
Tetra chloräthylen, Tetrachloräthan, Chlorbenzol, o-Dichlorbenzol. Bei den freien Aminen bilden sich wohl zunächst Carbaminsäure- chloride neben Aminsalz, welch letzteres se kundär mit Phosgen reagiert, während das primär gebildete Carbaminsäurechlorid rasch der intermolekularen Reaktion unterliegt. Beispiel 1: 5-Aminopentanol wird mit Chlorameisen säuremethylester in den Carbaminsäure- methylester übergeführt.
Man erhitzt dann dieses Urethan in Gegenwart von 1/200 Mol Kaliumcarbonat, bezogen auf 1 Mol Urethan, auf 140-200 C bis zum Nachlassen der Methanolabspaltung und hält die Temperatur schliesslich noch 6 Stunden im Vakuum von 0,5 mm auf 210 C, indem man gleichzeitig einen trockenen, vorgewärmten Stickstoff strom über die Schmelze hinwegstreichen lässt. Das Reaktionsprodukt wird aus der Schmelze zu Fäden ausgezogen.
Beispiel 2: N - Carboxymethylaminocapronsäurechlo- rid, hergestellt aus der Säure mit Thionyl- chlorid, lässt man in Benzollösung auf eine wässrige Lösung von 1.4-Aminabutanol in Ge genwart von Alkali unter guter Kühlung ein wirken. Das hierbei erhaltene Urethan der Formel CH3-O-CO-NH-(CH2)5-CO-NH-(CH2)4-OH kondensiert sich beim Erhitzen, insbesondere in- Gegenwart von Umesterungskatalysatoren, z.
B. 1/0o Mol Tolüolsulfosäure, bezogen auf ein Mol Urethan, mit weiteren Molekülen desselben Stoffes unter Abspaltung von Me thanol. Die Reaktion kann mit und ohne Lö sungsmittel durchgeführt werden. Ein ge eignetes Lösungsmittel ist o-Dichlorbenzol. Das Polyurethan wird nach dem Spritzguss verfahren zu Riemen oder Bändern ver arbeitet.
Beispiel 3: Trans - 4 - Aminocyclohexanol wird in Benzol mit der berechneten Menge Chlor ameisensäurephenylester zum Urethan acy- liert. Man destilliert dann das Benzol ab und erhitzt in Gegenwart einer Spur Natrium- phenolat in trockenem Phenol so lange auf l70 C, bis die Viskosität nicht mehr- zu nimmt. Das Reaktionsprodukt wird dann mit Aceton als Pulver gefällt. Es kann durch Wiederaufschmelzen und Erhitzen der Schmelze im Hochvakuum noch höher poly mer gemacht werden. Die erhaltenen Poly- urethane werden aus der Schmelze zu dicken Fäden (Borsten) versponnen.
Ein ähnliches Produkt erhält man, wenn man das 4-Aminocyclohexanol durch Ein tragen in überschüssigen Oxalester in Al kohol in den Oxaminsäureester überführt und diesen in Gegenwart von wenig Natrium- alkoholat im Stickstoffstrom erhitzt. Man kann auch durch Verseifen die entsprechende Oxaminsäure herstellen und diese kon densieren.
Process for the production of fibers, ribbons, foils or other flat structures from nitrogen-containing polycondensation products. The condensation of diisocyanates with glycols gives rise to high molecular weight polyurethanes which, when the degree of polymerisation is sufficiently high, can be used as the starting material for shaped structures, e.g. B. fibers can be used. Spinnable products of this type he keeps z. B. by reacting octamethylene diisocyanate with 1,4-butanediol (French. Patent No. 845917).
Similar products are formed when using diurethanes, e.g. B. hexamethylene-bis-carbaminsäurediphenylester, with glycols, z. B. decamethylene glycol, implemented (Italian Patent No. 382755).
Polyurethane compounds have already been produced from components which, in addition to the urethane-forming groups, already have amide groups (with the carbonyl group bonded to C carbonamide groups, urea groups, sulfonamide groups -NH-SO2-, sulfamide groups -NH-SO2-NH-) in open chain or contained in heterocyclic rings (French patent no. 879703).
The invention relates to a process for the production of fibers, tapes, films or other sheet-like structures from nitrogen-containing polycondensation products, which is characterized in that carbonic acid compounds of amino alcohols are used. Aminomercaptans with amino and hydroxyl or bonded to saturated carbon atoms. Sulfhydryl groups and with at least four chain-forming atoms between the terminal amino nitrogen and hydroxyl or. Mercapto group condenses and deforms by heating.
If appropriate, in the presence of solvents or diluents or catalysts that promote the elimination of ammonia or Al alcohol, in particular substances of the type of transesterification catalysts, eg. B. potassium carbonate, magnesium oxide, magnesium methylate, hydrogen halide, toluenesulfonic acid, naphthalenesulfonic acid, camphor sulfonic acid, zinc chloride, tin-2-chloride, can be used.
As starting materials for the implementation of the process, derivatives of amino alcohols, for example carbamic acid ester, urea and O-ester compounds of amino alcohols, are primarily suitable.
There are not only derivatives of simple Amiuoalkohole, z. B. derivatives of 4-aminobutanol, 5-aminopentanol, 4-aminocyclohexanol, 4-aminobutyl mercaptans (from benzoylaminobutyl chloride and potassium sulfhydrate with subsequent hydrolysis) in Be, but also more complicated Aminooxy- respectively. Aminomercapto compounds whose chain can be interrupted by heteroatoms or hetero groups, such as O, S, SO2, e.g. B. Derivatives of # -aminobutyl - # '- oxypropyl sulfide (from benzoyl-aminobutyl mercaptan and 3-bromopropanol). In particular, such derivatives of Aminooxy- respectively.
Aminomercapto compounds included, the chain of which is replaced by amide groups, e.g. B. carbon-bonded carbonamide groups, urea groups, sulfonamide groups, sulfamide groups, is interrupted. These amide groups can be contained in the open chain as well as in heterocyclic nuclei joined into the chain or in both at the same time (cf. French Patent No. 879703).
One embodiment of the process consists in that phosgene is allowed to act on the amino alcohols or salts thereof with hydrogen halide acids and then the intermediates are advantageously heated in the presence of a diluent, the further condensation taking place with elimination of hydrogen halide. It can be assumed that in the case of the salts, chloroformic acid esters are first formed, whereupon the chloride group reacts with the nitrogen, which has been saturated by hydrogen halide, with elimination of 2 moles of hydrogen halide. As a solvent or diluent for the reaction are particularly suitable halogenated hydrocarbons with a boiling point between 110 and 170 C, z. B.
Tetra chloroethylene, tetrachloroethane, chlorobenzene, o-dichlorobenzene. In the case of the free amines, carbamic acid chlorides are formed in addition to the amine salt, which latter reacts secondarily with phosgene, while the primarily formed carbamic acid chloride quickly undergoes the intermolecular reaction. Example 1: 5-aminopentanol is converted into the methyl carbamic acid ester with methyl chloroformate.
This urethane is then heated in the presence of 1/200 mol of potassium carbonate, based on 1 mol of urethane, to 140-200 ° C. until the elimination of methanol subsides and the temperature is finally maintained for 6 hours in a vacuum from 0.5 mm to 210 ° C. by at the same time a dry, preheated nitrogen stream is allowed to sweep over the melt. The reaction product is drawn out of the melt into threads.
Example 2: N-carboxymethylaminocaproic acid chloride, prepared from the acid with thionyl chloride, is allowed to act in benzene solution on an aqueous solution of 1,4-aminabutanol in the presence of alkali with good cooling. The urethane of the formula CH3-O-CO-NH- (CH2) 5-CO-NH- (CH2) 4-OH obtained here condenses on heating, especially in the presence of transesterification catalysts, e.g.
B. 1 / 0o mol of toluene sulfonic acid, based on one mole of urethane, with other molecules of the same substance with elimination of methanol. The reaction can be carried out with or without a solvent. A suitable solvent is o-dichlorobenzene. The polyurethane is processed into belts or bands after the injection molding process.
Example 3: Trans - 4 - aminocyclohexanol is acylated to urethane in benzene with the calculated amount of phenyl chloroformate. The benzene is then distilled off and heated to 170 ° C. in the presence of a trace of sodium phenolate in dry phenol until the viscosity no longer increases. The reaction product is then precipitated as a powder with acetone. It can be made even higher polymer by re-melting and heating the melt in a high vacuum. The resulting polyurethanes are spun from the melt into thick threads (bristles).
A similar product is obtained if the 4-aminocyclohexanol is converted into the oxamic acid ester by a carry in excess oxalate in alcohol and heated in the presence of a little sodium alcoholate in a stream of nitrogen. The corresponding oxamic acid can also be produced by saponification and condense this.
