Description
Verfahren zur Darstellung eines Bis-(halogen-oxyaryl)-oxyds. Es wurde gefunden, dass durch Umwand lung von Bis-(oxyaryl)-oxyden bezw. ihren Substitutionsprodukten in Bis-(halogen-oxy- aryl)-oxyde bezw. ihre Substitutionsprodukte nach an sich üblichen Arbeitsweisen wert volle Verbindungen erhalten werden, die sich besonders durch ihre Desinfektionskraft, z. B. als Harndesinfieientia, auszeichnen.
Zur Darstellung der Bis-(halogen-oxyaryl)- oxyde bezw. ihrer Substitutionsprodukte kann man in der Weise verfahren, dass man auf Bis-(oxyaryl)-oxyde bezw. deren Substitutions- produkte Halogen oder halogenierende Mittel zur Einwirkung bringt.
In der genannten Weise kann man ein oder mehrere Halogenatome in die als Aus gangsmaterial gewählte Verbindung einführen.
Anstatt dier Halogenatome unmittelbar einzuführen, kann man auch so vorgehen, dass man in Bis-(oxyaryl)-oxyden vorhandene Substituenten, die wie zum Beispiel die Aminogruppe in bekannter Weise durch Halogenatome ersetzt werden. können, gegen Halogen austauscht.
Als Arylreste können in den Verbindungen isozyklische aromatische Ringsysteme, z. B. Phenyl-, Naphthyl-, Tetrahydronaphthyl und ähnliche Reste enthalten sein. Je nach der Wahl der Ausgangsmaterialien erhält man symmetrisch oder unsymmetrisch zubstituierte Bis-(halogen-oxyaryl)-oxyde.
Cregenstand vorliegender Erfindung ist nun ein Verfahren zur Darstellung von Bis-(2-oxy- 6-bi,omphenyl)-oxyd, dadurch gekennzeichnet, dass man auf Bis-(2-oxyplienyl)-oxyd ein bro- mierendes Mittel einwirken lässt. Die neue Verbindung soll als Desinfektionsmittel Ver wendung finden. <I>Beispiel:</I> <B>10</B> Gewichtsteile Bis-(2-oxyphenyl)-oxyd (hergestellt nach Berichte<B>39 [1906], S.</B> 624) werden in der Wärme in<B>50</B> Gewichtsteilen Eisessig gelöst.
Bei Wasserbadtemperatur tropft man hierzu eine Lösung von<B>16</B> Ge wichtsteilen Brom in 20 Gewichtsteilen Eis essig und erwärmt bis zum Aufhören der Bromwasserstoffentwicklung. Die erhaltene Lösung.wird filtriert und im Vakuum zur Kristallisation eingeengt. Das Bis-(2-oxy-5- bromphenyl)-oxyd kristallisiert dann in zu Rosetten angeordneten Nädelchen aus. Aus viel Wasser kristallisiert es in weissen Na deln vom Schmelzpunkt<B>126 0.</B>
Process for the preparation of a bis (halo-oxyaryl) oxide. It has been found that by converting bis (oxyaryl) oxides BEZW. their substitution products in bis (halogen-oxy-aryl) oxides respectively. their substitution products are obtained according to usual working methods valuable compounds that are particularly characterized by their disinfectant power, eg. B. as Urndisinfieientia distinguish.
To represent the bis (halogen-oxyaryl) - oxides respectively. their substitution products can be proceeded in such a way that one BEZW on bis (oxyaryl) oxides. whose substitution products cause halogen or halogenating agents to act.
In the manner mentioned, one or more halogen atoms can be introduced into the compound selected as the starting material.
Instead of introducing the halogen atoms directly, one can also proceed in such a way that substituents present in bis (oxyaryl) oxides which, such as the amino group, are replaced by halogen atoms in a known manner. can be exchanged for halogen.
Isocyclic aromatic ring systems such. B. phenyl, naphthyl, tetrahydronaphthyl and similar radicals. Depending on the choice of starting materials, symmetrically or asymmetrically substituted bis (halo-oxyaryl) oxides are obtained.
Cregenstand of the present invention is a process for the preparation of bis (2-oxy-6-bi, omphenyl) oxide, characterized in that a brominating agent is allowed to act on bis (2-oxyplienyl) oxide. The new compound is to be used as a disinfectant. <I> Example: </I> <B> 10 </B> parts by weight of bis (2-oxyphenyl) oxide (produced according to reports <B> 39 [1906], p. </B> 624) are in the Heat dissolved in <B> 50 </B> parts by weight of glacial acetic acid.
At the water bath temperature, a solution of 16 parts by weight of bromine in 20 parts by weight of glacial acetic acid is added dropwise and the mixture is heated until the evolution of hydrogen bromide ceases. The solution obtained is filtered and concentrated in vacuo to crystallize. The bis (2-oxy-5-bromophenyl) oxide then crystallizes out in needles arranged in rosettes. From a lot of water it crystallizes in white needles with a melting point of <B> 126 0. </B>
