Description
Verfahren zur Herstellung eines Lösungsmittels für hochmolekulare Verbindungen. Es wurde gefunden, dass man zu wert vollen Lösungsmitteln für hochmolekulare Verbindungen gelangt, wenn man Dihalogen- verbindungen der allgemeinen Formel
EMI0001.0005
worin R den Rest -CH2-CHZ-CH2- oder CH"- C112- bedeutet,
mit $upfercyanür umsetzt und die entstandenen 3-Halogen-2-cyan-tetra- hydropyrane bezw. 3-Halogen-2-cyan-tetra- hydrofurane gegebenenfalls durch Behand lung mit Halogenwasserstoff abspaltenden Mitteln in 2-Cyandihydropyrane bezw. 2- Cyandihydrofurane überführt.
Die genannten Verbindungen sind sämt lich bisher unbekannte Körper und eignen sich vorzüglich als Lösungsmittel für thermo plastische hochmolekulare Verbindungen. Vorliegendes Patent bezieht sich nun auf ein Verfahren zur Herstellung eines Lösungs mittels für hochmolekulare Verbindungen, dadurch gekennzeichnet, dass man 2.3-Di- chlortetrahydropyran mit Kupfercyanür um setzt.
Das so erhaltene 2-Cyan-3-chlortetrahy- dropyran der Formel
EMI0001.0024
ist eine farblose Flüssigkeit vom Kpa 98 bis 100 und ist vorzüglich geeignet als Lösungs mittel für thermoplastische hochmolekulare Verbindungen.
<I>Beispiel:</I> Ein Gemisch von 155 Teilen 2.3-Dichlor- tetrahydropyran, etwa 150 Teilen Toluol und <B>100</B> Teilen Kupfercyanür wird mehrere Stun den unter Rühren auf 80-90 erwärmt. Hier auf wird von Kupfersalzen abfiltriert und das Filtrat fraktioniert. Das 2-Cyan-3-chlor- tctrahydropyran geht bei 8 mm Druck bei 98-l00 als farblose Flüssigkeit über.
Process for the preparation of a solvent for high molecular compounds. It has been found that valuable solvents for high molecular weight compounds can be obtained if dihalogen compounds of the general formula are used
EMI0001.0005
where R is the radical -CH2-CHZ-CH2- or CH "- C112-,
with $ upfercyanür reacts and the resulting 3-halo-2-cyano-tetrahydropyrane respectively. 3-halo-2-cyano-tetrahydrofurans, if appropriate by treatment with agents which split off hydrogen halide, respectively, in 2-cyandihydropyrans. 2- Cyandihydrofurane transferred.
The compounds mentioned are all previously unknown bodies and are ideally suited as solvents for thermoplastic high-molecular compounds. The present patent now relates to a method for producing a solvent for high molecular weight compounds, characterized in that 2,3-dichlorotetrahydropyran is reacted with copper cyanuric.
The 2-cyano-3-chlorotetrahydropyran of the formula obtained in this way
EMI0001.0024
is a colorless liquid from Kpa 98 to 100 and is particularly suitable as a solvent for thermoplastic high-molecular compounds.
<I> Example: </I> A mixture of 155 parts of 2,3-dichlorotetrahydropyran, about 150 parts of toluene and <B> 100 </B> parts of copper cyanide is heated to 80-90 for several hours while stirring. Here, copper salts are filtered off and the filtrate is fractionated. The 2-cyano-3-chlorotrahydropyran passes over as a colorless liquid at 8 mm pressure at 98-100.
