Description
Verfahren zur Darstellung eines hochchlorierten, sticlistofhaltigen, hydroaromatischen Produktes. Es wurde gefunden, dass man beim Chlo rieren.des salzsauren Salzes von ss-Naphtyl- amin in einem indifferenten Suspensionsmittel, das keine Hydrolyse zustande kommen lässt, und bei völligem Ausschluss von Feuchtigkeit zu einem hochchlorierten Produkt kommt, das sich vom Tetrahydronaphtalin ableitet und das, was das Wichtigste ist, noch Stick stoff enthält. Weder diese Darstellungsmethode, noch der erhaltene Körper selbst waren bis heute bekannt.
Das Verfahren wird erläutert durch fol gendes Beispiel.
<I>Beispiel:</I> In eine Lösung von 100 gr ss-Naphtyl- amin in 800 cm' Benzol wird unter Rühren gasförmige Salzsäure eingeleitet, bis reichlich Salzsäure entweicht. Dann wird gekühlt und Chlorgas bis zur Sättigung eingeleitet, hier auf allmählich auf dem Wasserbad erwärmt, wobei Lösung eintritt. Diese Lösung wird im Vakuum eingeengt, das Benzol im Vakuum durch wiederholten Benzinzusatz vertrieben, wobei das Chloradditionsprodukt sich auszu scheiden beginnt, dann wird abgekühlt und abgesaugt. Man erhält so ungefähr 200 gr eines Produktes, das bei 115 o schmilzt, während der Schmelzpunkt des reinen Pro duktes bei 118,5 liegt.
Der erhaltene Körper, das Pentachlor-p- chlorlzetiminotetrahydronaphtalin der Formel:
EMI0001.0014
bildet prismatische Kristalle vom Schmelz punkt 118,5 0. Analyse: Chlor berechnet G0,48 %, gefunden<B>60,6</B> %. Er soll als neues Zwischenprodukt für die Farbstoffindustrie Verwendung finden.
Process for the preparation of a highly chlorinated, hydroaromatic product containing sticlistof. It has been found that chlorination of the hydrochloric acid salt of ß-naphthylamine in an inert suspending agent that does not allow hydrolysis to occur and, with the complete exclusion of moisture, results in a highly chlorinated product that is derived from tetrahydronaphthalene and that Most importantly, it still contains nitrogen. Neither this method of representation nor the body itself was known to this day.
The method is illustrated by the following example.
<I> Example: </I> Gaseous hydrochloric acid is introduced into a solution of 100 gr ss-naphthylamine in 800 cm 'benzene with stirring until a large amount of hydrochloric acid escapes. Then it is cooled and chlorine gas is introduced until it is saturated, here it is gradually warmed up on the water bath, whereby solution occurs. This solution is concentrated in vacuo, the benzene expelled in vacuo by repeated addition of gasoline, the chlorine addition product begins to separate out, then it is cooled and filtered off with suction. This gives about 200 g of a product that melts at 115 o, while the melting point of the pure product is 118.5.
The body obtained, the pentachloro-p-chlorlzetiminotetrahydronaphthalene of the formula:
EMI0001.0014
forms prismatic crystals with a melting point of 118.5 0. Analysis: Chlorine calculated G0.48%, found <B> 60.6 </B>%. It is to be used as a new intermediate product for the dye industry.
