Description
Verfahren zur Herstellung einer organischen Chlor-verbindung. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer organi schen Chlorverbindung, das dadurch gekenn zeichnet ist, dass man auf ein Metallsalz eines Hexadecandisäure-1.16-monoesters elemen tares Chlor einwirken lässt und den entstan denen 15-Chlorpentadecansäure-l-ester mit einem verseifenden Mittel in die freie, chlo rierte Monocarbonsäure überführt. Die neue Verbindung schmilzt bei 59 bis 60 . Sie stellt ein wichtiges Zwischenprodukt für die Her stellung von Riechstoffen und Arzneimitteln dar.
Als besonders geeignet erwiesen sich das Silbersalz, die Mercuro- und Mercurisalze, sowie das Thallosalz der halbseitig verester- ten Dicarbonsäure.
Vorteilhaft arbeitet man in Gegenwart von indifferenten Lösungs- oder Verdün nungsmitteln, wie Luft, CC14, CHC13 oder Äther.
. Zur Verseifung des chlorierten Monocar- bonsäureesters verwendet man mit Vorteil eine Eisessig-Bromwasserstofflösung. Beispiel: In eine Aufschlämmung von 421 g Sil bersalz des Hexadecandisäuremonoesters und 800 g Tetrachlorkohlenstoff leitet man unter gelegentlichem Kühlen so lange Chlor ein, bis die CO=-Entwicklung beendet ist und der Rückstand von AgCl rein weiss erscheint.
Die Lösung wird vom AgCl abfiltriert, das AgCl am Soxhlet mit Tetrachlorkohlenstoff extra hiert und die vereinigten Filtrate destilliert. Nach dem Entfernen des Tetrachlorkohlen- stoffes wird der Rückstand in bekannter Weise mittels Eisessigchlorwasserstoff ver seift.
Man erhält schliesslich 210 g 15-Chlor- pentadecans@äure-1, das sind <B>76%</B> der Theo rie (Smp. 59 bis<B>60').</B>
Process for the production of an organic chlorine compound. The subject of the present patent is a process for the production of an organic chlorine compound, which is characterized in that elementary chlorine is allowed to act on a metal salt of a hexadecanedioic acid 1.16-monoester and the 15-chloropentadecanoic acid-l-ester formed with a saponifying agent Agent converted into the free, chlorinated monocarboxylic acid. The new compound melts at 59 to 60. It is an important intermediate for the manufacture of fragrances and drugs.
The silver salt, the mercurous and mercuric salts, and the thallo salt of the half-esterified dicarboxylic acid have proven to be particularly suitable.
It is advantageous to work in the presence of inert solvents or diluents such as air, CC14, CHC13 or ether.
. A glacial acetic acid / hydrogen bromide solution is advantageously used to saponify the chlorinated monocarboxylic acid ester. Example: Chlorine is introduced into a slurry of 421 g of the silver salt of hexadecanedioic acid monoester and 800 g of carbon tetrachloride with occasional cooling until the evolution of CO = has ended and the AgCl residue appears pure white.
The solution is filtered off from the AgCl, the AgCl is extracted on the Soxhlet with carbon tetrachloride and the combined filtrates are distilled. After the carbon tetrachloride has been removed, the residue is soaped off in a known manner using hydrochloric acetic acid.
Finally, 210 g of 15-chloropentadecane 1-acid are obtained, that is <B> 76% </B> of the theory (melting point 59 to <B> 60 '). </B>
