Description
Verfahren zur Herstellung eines Kondensationsproduktes.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden sationsproduktes der Formel
EMI1.1
dadureh gekennzeichnet, dass man 2-Chlor-5 trifluormethyl-anilin mit einem Halogenkoh- lensäurederivat reagieren lässt und das erhaltene reaktive Carbaminsäurederivat mit 2- amino-4, 4'-diehlor-1, 1'-diphenylthioäther-6'- sulfonsaurem Natrium umsetzt.
Eine Ausführungsform des erfindungsgemässen Verfahrens besteht darin, dass man 2-Chlor-5-trifluormethyl-anilin mit Phosgen reagieren lässt und das erhaltene 2-Chlor-5-tri fluormethylphenylearbaminsäurechlorid mit 2-amino-4, 4'-diehlor-1, 1'-diphenylthioäther-6'- sulfonsaurem Natrium umsetzt. Dabei arbeitet man vorzugsweise in Gegenwart einer tertiä- ren Base als Kondensationsmittel. Pyridin oder Chinolin sind für diesen Zweck vor allem geeignet.
Des weiteren kann man 2-Chlor-5-trifluor methyl-anilin mit Phosgen bei erhöhter Temperatur umsetzen und das erhaltene 2-Chlor5-trifluormethylphenylisocyanat mit 2-amino4, 4'-dichlor-1, 1'-diphenylthioäther-6'-sulfon- saurem Natrium zur Reaktion bringen, wobei man die Verbindung der obigen Formel in guter Ausbeute und vorzüglicher Reinheit erhält. Als Lösungsmittel eignet sieh für diese Art der Umsetzung vor allem Acetonitril.
Schliesslich besteht eine Ausführungsform darin, dass man 2-Chlor-5-trifluormethyl-anilin mit einem Halogenkohlensäureester reagieren lässt und den erhaltenen 2-Chlor-5-tri- fluormethylphenylcarbaminsäureester mit 2amino-4, 4'-dichlor-1, 1'-diphenylthioäther-6'- sulfonsaurem Natrium umsetzt.
Als Halogenkohlensäureester kommen hauptschlich niedere Alkyl-oder Arylester in Frage. Der Umsatz kann vorteilhaft in Was- ser vorgenommen werden.
Das neue Kondensationsprodukt bildet ein helles, in heissem Wasser klar lösliches Kri- stallpulver, das als Mottenschutzmittel verwendet werden kann.
Beispiel 1 : a) 300 Teile trockenes Benzol werden bei 70 mit Phosgen gesättigt ; dazu wird unter Rühren und Einleiten von Phosgen eine Lö- sung von 100 Teilen 2-Chlor-5-trifluormethylanilin in 300 Teilen trockenem Benzol bei 65 bis 70 zugetropft. Nach einiger Zeit erhitzt man bis zum Rückfluss und leitet so lange Phosgen ein, bis nur noch kleine Mengen des verwendeten Amins ungelöst sind. Die benzolische Lösung wird hierauf filtriert, das Benzol abdestilliert und das 2-Chlor-5-trifluor methylphenyl-isocyanat fraktioniert.
Kp75 : 122-124 ; Ausbeute : 90 Teile. b) 12, 4 Teile 2-amino-4, 4'-dichlor-1, 1'-di phenylthioäther-6'-sulfonsaures Natrium werden in 60 Teilen Acetonitril gelöst, mit 7, 38 Teilen 2-Chlor-5-trifluormethylphenyl-isocya- nat versetzt und sechs Stunden auf dem Wasserbad erwärmt. Die Reaktionslösung wird filtriert und das Lösungsmittel verdampft. Ausbeute : 15 Teile.
Das Kondensationsprodukt wird in 3500 Teilen Wasser von 80-85 gelöst, mit wenig Tierkohle versetzt und heiss filtriert. Nach Zugabe von 100 Teilen gesättigter Kochsalz- lösung scheidet sich das Kondensationspro- dukt aus.
Nach dem Erkalten wird es gesammelt und im Vakuum getrocknet. Um es von Kochsalz zu befreien, kann es aus absolutem Alkohol ausgezogen werden. Das neue Kondensationsprodukt bildet nach dem Trocknen und AIahlen ein helles, in heissem Wasser klar lösliches Pulver.
Beispiel 2 :
Das aus Phosgen und 2-Chlor-5-trifluor- methyl-anilin in einem trockenen inerten Lö sungsmittel hergestellte 2-Chlor-5-trifluor methylphenylcarbaminsäurechlorid ergibt unter Zusatz von Pyridin als Kondensationsmit- tel mit 2-amino-4, 4'-diehlor-1, 1'-diphenylthio äther-6'-sulfonsaurem Natrium den in Beispiel 1 b) beschriebenen Harnstoff in befriedigender Ausbeute.
Beispiel 3 :
Der aus Chlorkohlensäurephenylester und 2-Chlor-5-trifluormethylanilin in troekenem Pyridin hergestellte 2-Chlor-5-trifluormethyl- phenylearbaminsäurephenylester liefert durch Umsetzung mit 2-amino-4, 4'-dichlor-1, 1'-diphe nylthioäther-6'-sulfonsaurem Natrium in hei ssem Wasser den in Beispiel 1 b) beschrie- benen Harnstoff ; anstatt des 2-Chlor-5-tri fluormethylphenyl-earbaminsäurephenylesters kann auch der entsprechende Methylester verwendet werden.
Process for the production of a condensation product.
The present patent relates to a process for the preparation of a condensation product of the formula
EMI1.1
characterized by the fact that 2-chloro-5-trifluoromethyl-aniline is allowed to react with a halogenated carbonic acid derivative and the reactive carbamic acid derivative obtained is reacted with 2-amino-4, 4'-dichloro-1, 1'-diphenylthioether-6'-sulfonic acid sodium .
One embodiment of the process according to the invention is that 2-chloro-5-trifluoromethyl-aniline is allowed to react with phosgene and the 2-chloro-5-trifluoromethylphenylearbamic acid chloride obtained is treated with 2-amino-4, 4'-diehlor-1, 1 ' -diphenylthioether-6'-sulfonic acid sodium converts. The operation is preferably carried out in the presence of a tertiary base as the condensing agent. Pyridine or quinoline are particularly suitable for this purpose.
In addition, 2-chloro-5-trifluoro-methyl-aniline can be reacted with phosgene at elevated temperature and the 2-chloro-5-trifluoromethylphenyl isocyanate obtained with 2-amino4, 4'-dichloro-1, 1'-diphenylthioether-6'-sulfone bring acidic sodium to react to give the compound of the above formula in good yield and excellent purity. A particularly suitable solvent for this type of reaction is acetonitrile.
Finally, one embodiment consists in reacting 2-chloro-5-trifluoromethyl-aniline with a halocarbon acid ester and allowing the 2-chloro-5-trifluoromethylphenylcarbamic acid ester obtained to react with 2 amino-4, 4'-dichloro-1, 1'-diphenylthioether -6'- sulfonic acid sodium converts.
Mainly lower alkyl or aryl esters are suitable as halocarbonic acid esters. The conversion can advantageously be carried out in water.
The new condensation product forms a pale crystal powder which is clearly soluble in hot water and which can be used as a moth repellent.
Example 1: a) 300 parts of dry benzene are saturated at 70 with phosgene; to this end, a solution of 100 parts of 2-chloro-5-trifluoromethylaniline in 300 parts of dry benzene at 65 to 70 is added dropwise with stirring and introduction of phosgene. After some time, the mixture is heated to reflux and phosgene is passed in until only small amounts of the amine used are undissolved. The benzene solution is then filtered, the benzene is distilled off and the 2-chloro-5-trifluoro methylphenyl isocyanate is fractionated.
Bp75: 122-124; Yield: 90 parts. b) 12.4 parts of 2-amino-4, 4'-dichloro-1, 1'-di phenylthioether-6'-sulfonic acid sodium are dissolved in 60 parts of acetonitrile, with 7.38 parts of 2-chloro-5-trifluoromethylphenyl isocyanate was added and the mixture was heated on a water bath for six hours. The reaction solution is filtered and the solvent is evaporated. Yield: 15 parts.
The condensation product is dissolved in 3500 parts of 80-85 water, mixed with a little animal charcoal and filtered hot. After adding 100 parts of saturated sodium chloride solution, the condensation product separates out.
After cooling, it is collected and dried in vacuo. In order to rid it of table salt, it can be extracted from absolute alcohol. After drying and grinding, the new condensation product forms a pale powder that is clearly soluble in hot water.
Example 2:
The 2-chloro-5-trifluoromethylphenylcarbamic acid chloride prepared from phosgene and 2-chloro-5-trifluoromethyl-aniline in a dry, inert solvent yields methylphenylcarbamic acid chloride with the addition of pyridine as a condensing agent with 2-amino-4,4'-diehlor -1, 1'-diphenylthio ether-6'-sulfonic acid sodium, the urea described in Example 1 b) in a satisfactory yield.
Example 3:
The 2-chloro-5-trifluoromethylphenylearbamic acid phenyl ester prepared from chlorocarbonic acid phenyl ester and 2-chloro-5-trifluoromethylaniline in dry pyridine gives by reaction with 2-amino-4, 4'-dichloro-1, 1'-diphenylthioether-6'- Sodium sulfonic acid in hot water, the urea described in Example 1 b); instead of the 2-chloro-5-trifluoromethylphenyl-earbamic acid phenyl ester, the corresponding methyl ester can also be used.
