Description
Verfahren zur Herstellung von Derivaten kernmercurierter Phenole. In weiterer Ausbildung des durch Patent 423 378 geschützten Verfahrens zur Herstellung von Derivaten kernmercurierter Phenole wurde gefunden, daß sowohl fertiggebildetes Quecksilberoxycyanid als auch Verbindungen, aus denen es entsteht, außerordentlich leicht mit Phenolen reagieren. Die Reaktion erfolgt nach der Gleichung mit großer Schnelligkeit schon bei Temperaturen von etwa 6o'. Es bilden sich dabei die Alkalisalze der in dem Hauptpatent beschriebenen Cyanmercuriphenole, die sich durch Beständigkeit und Leichtlöslichkeit auszeichnen.Process for the preparation of derivatives of nuclear mercured phenols. In a further development of the process for the preparation of derivatives of nuclear mercurated phenols, which is protected by patent 423,378, it was found that both ready-formed mercury oxycyanide and compounds from which it is formed react extremely easily with phenols. The reaction takes place according to the equation with great speed even at temperatures of about 6o '. The alkali salts of the cyano-mercuriphenols described in the main patent are formed, which are characterized by stability and easy solubility.
Aus diesen Alkalisalzen werden durch verdünnte Schwefelsäure oder Kohlensäure die freien Cyanmercuriphenole als inWasser schwer lösliche Verbindungen gefällt.These alkali salts are converted into dilute sulfuric acid or Carbonic acid the free cyano mercuric phenols as compounds that are sparingly soluble in water pleases.
Beispiele. i. 2,1 kg o-Kresol werden unter Zusatz von wenig Wasser mit 1,9 kg Natronlauge von 45' B6 in Lösung gebracht und in diese Lösung 4,68 kg Quecksilberoxycyanid unter Rühren in der Wärme eingetragen. Bei etwa 6o bis 7o° tritt Lösung ein. Die Lösung scheidet beim Neutralisieren mit verdünnter Schwefelsäure oder auf Zusatz von Natriumbicarbonat Cyanmercuri-o-kresol als eine farblose, kristallinische Masse ab, welche sich in Natronlauge völlig klar auflöst.Examples. i. 2.1 kg of o-cresol are added with a little water brought into solution with 1.9 kg of sodium hydroxide solution of 45 'B6 and in this solution 4.68 kg Mercury oxycyanide entered with stirring in the heat. At about 6o to 7o ° solution occurs. The solution separates when neutralized with dilute sulfuric acid or on the addition of sodium bicarbonate Cyanmercuri-o-cresol as a colorless, crystalline one Mass from, which dissolves completely clear in sodium hydroxide solution.
2. 2,1 kg o-Kresol werden mit 1,9 kg Natronlauge von 45' B6 unter Zusatz von wenig Wasser gelöst. Zu dieser Lösung läßt man ein Gemisch fließen, welches man durch Versetzen von 5,4 kg Quecksilberchlorid mit 9,8 kg Natriumcyanid in io kg Wasser erhalten hat, und erwärmt die Lösung unter weiterem Zusatz von 1,9 kg Natronlauge von 45' B6 auf 7o bis 8o°. Aus der Lösung wird durch verdünnte Säuren das Cyanmercuri-o-kresol als farblose, in Natronlauge leicht lösliche Masse abgeschieden.2. 2.1 kg of o-cresol are mixed with 1.9 kg of sodium hydroxide solution from 45 'B6 Dissolved a little water added. A mixture is allowed to flow into this solution, which by adding 5.4 kg of mercury chloride with 9.8 kg of sodium cyanide in io kg of water has been obtained, and the solution is heated with a further addition of 1.9 kg Caustic soda from 45 'B6 to 7o to 8o °. The solution becomes through dilute acids the Cyanmercuri-o-cresol deposited as a colorless, easily soluble in sodium hydroxide mass.
3. i,2 kg o-Chlorphenol werden in a 1 Wasser unter Zusatz von o,8 kg Natronlauge (von q.o Bfi) gelöst und in dieser Lösung 2,4 kg Quecksilberoxycyanid in der Wärme eingetragen. Das Oxycyanid geht sofort in Lösung, die Lösung wird nach einstündigem Erwärmen abfiltriert und aus ihr durch verdünnte Schwefelsäure oder Kohlensäure das Cyanmercuri-ochlorphenol als farblose, in Wasser lösliche Kristallmasse gefällt.3. 1.2 kg of o-chlorophenol are dissolved in a 1 of water with the addition of 0.8 kg of sodium hydroxide solution (from q.o Bfi) dissolved and 2.4 kg of mercury oxycyanide in this solution entered in the heat. The oxycyanide goes into solution immediately, the solution is after One hour of heating and filtered off from it by dilute sulfuric acid or Carbonic acid, the Cyanmercuri-ochlorphenol, as a colorless, water-soluble crystal mass pleases.
