Zusatz zum Patente 106504 vom 21. OktoberAddendum to patent 106504 of October 21
Patentirt im Deutschen Reiche vom 15. Februar 1899 ab. Längste Dauer: 20. Oktober 1913.Patented in the German Empire on February 15, 1899. Longest duration: October 20, 1913.
Es wurde gefunden, dafs sich in dem Verfahren des Patentes 106504 das dort verwendete m-Kresol durch sein Homologes, das Thymol, ersetzen läfst. Man kann auf diese Weise das bisher schwer zugänglich gewesene Monojodthymol in einfacher Weise erhalten.It has been found that the process of patent 106504 is the one used there m-cresol can be replaced by its homologue, thymol. You can do it this way Obtain monoiodothymol previously difficult to access in a simple manner.
I. 75 kg Thymol werden in 60 kg Natronlauge (400 B.) und 1000 1 Wasser gelöst. Zu dieser Lösung läfst man unter Rühren eine solche von 127 kg Jod und 127 kg Jodkalium in 400 1 Wasser einfliefsen.I. 75 kg of thymol are dissolved in 60 kg of sodium hydroxide solution (40 0 B.) and 1000 1 of water. A solution of 127 kg of iodine and 127 kg of potassium iodide in 400 l of water is run into this solution with stirring.
Man kühlt hiernach die etwas warm gewordene Reactionsmasse ab, macht eventuell durch Zusatz von verdünnter Schwefelsäure schwach sauer und filtrirt das abgeschiedene Product von der Mutterlauge ab. Durch Umkrystallisiren aus Ligrom erhält man das Monojodthymol vom Schmelzpunkt 68 bis 69 °.The reaction mass, which has become somewhat warm, is then cooled down, possibly done weakly acidic by adding dilute sulfuric acid and filtering the separated Product from the mother liquor. Monoiodothymol is obtained by recrystallizing from ligrom from melting point 68 to 69 °.
II. Zu einer Lösung von 127 kg Jod in 600 kg Natronlauge und 2000 1 Wasser läfst man 75 kg Thymol zufliefsen. Beim Ansäuern dieser Lösung fällt das Monojodthymol aus und wird auf die gleiche Weise wie bei Beispiel I isolirt.II. Dissolves 127 kg of iodine in 600 kg of sodium hydroxide solution and 2000 l of water one inflow 75 kg of thymol. When this solution is acidified, the monoiodothymol precipitates and is isolated in the same way as in Example I.
