Description
Verfahren zur Darstellung eines Harnstoifderivates. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Harn stoffderivates der Formel
EMI0001.0002
dadurch gekennzeichnet, dass man 2-Amino- 4'-chlor -3'-methyl-1,1'-diphenyl äther-4-sulfon- säure mit Phosgen umsetzt. Das neue Harn atoffderivat bildet als Natriumsalz ein helles, gut wasserlösliches Pulver, das sieh zur Ver wendung als Mottenschutzmittel eignet.
<I>Beispiel:</I> 18 Teile 2-Amino-4'-chlor-3'-methyl-1,1'- diphenyläther-4-sulforisäure werden in 250 Teilen Wasser mit der nötigen Menge 10 %- iger Sodalösung in Lösung gebracht. Zu dieser Lösung gibt man 25 Teile kristallisiertes Natriumacetat hinzu und leitet bei 40 bis <B>50' 0</B> Phosgen ein, bis eine Probe kein freies Amin mehr anzeigt. Hierauf wird die Lösung mittels Soda genau neutralisiert und das Natriumsalz des neuen Harnstoffderivates durch Zusatz von Kochsalz abgeschieden.
Es wird nach dem Abtrennen, Trocknen und Mahlen als helles, gut wasserlösliches Pulver erhalten. Die Ausbeute ist quantitativ.
Method for the preparation of a urea derivative. The subject of the present patent is a process for the preparation of a urea derivative of the formula
EMI0001.0002
characterized in that 2-amino-4'-chloro -3'-methyl-1,1'-diphenyl ether-4-sulfonic acid is reacted with phosgene. The new urea derivative forms a pale, water-soluble powder as a sodium salt, which is suitable for use as a moth repellent.
<I> Example: </I> 18 parts of 2-amino-4'-chloro-3'-methyl-1,1'-diphenylether-4-sulforic acid are dissolved in 250 parts of water with the necessary amount of 10% soda solution Solution brought. 25 parts of crystallized sodium acetate are added to this solution and phosgene is passed in at 40 to 50 0 until a sample no longer shows any free amine. The solution is then precisely neutralized using soda and the sodium salt of the new urea derivative is deposited by adding sodium chloride.
It is obtained as a pale, readily water-soluble powder after it has been separated off, dried and ground. The yield is quantitative.
