Description
Verfahren zur Darstellung eines Gerbstoffes. Es ist bis dahin nicht bekannt gewesen, dass f-Chlormethylensalicylsäure, beziehungs weise deren Derivate und Substitutionspro- dukte, mit den Salzen von aromatischen Oxysulfosäuren zu Verbindungen zusammen treten, die als Gerbstoffe von besonderer Bedeutung sind.
Das den Gegenstand des vorliegenden Patentes bildende Verfahren ist dadurch ge kennzeichnet, dass die D-Chlormethylensalicyl- säure der Formel
EMI0001.0007
in verdünnt saurer Lösung mit pheriol-p-sulfo- saurem Natrium kondensiert wird.
Das Produkt bat in schwach saurer Lö sung stark leimfällende Eigenschaften und verwandelt die tierische Blösse in ein wert volles, weisses und volles Leder.
<I>Beispiel</I> 184 Teile SZ-Chlor-methylensalicylsäure werden in 400 Teilen 30 o@'oiger Essigsäure mit<B>197</B> Teilen pheriolsulfosaurem Natrium während 6 Stunden am Rückflusskühler ge kocht. Rühren ist von x7orteil. Den Kolben inhalt giesst man in Eiswasser, wobei sich das neue Kondensationsprodukt als dickes Harz ausscheidet, das langsam hart wird. Dasselbe wird nach dem Auswaschen mit Hilfe von Natriumacetat mit wenig Wasser iri Lösung gebracht, essigsauer gestellt und ist nun als Gerbstoff ohne weiteres verwendbar.
Process for the preparation of a tanning agent. Up until then it was not known that f-chloromethylene salicylic acid, or its derivatives and substitution products, combine with the salts of aromatic oxysulfonic acids to form compounds which are of particular importance as tannins.
The method forming the subject of the present patent is characterized in that the D-chloromethylene salicylic acid of the formula
EMI0001.0007
is condensed in dilute acidic solution with pheriol-p-sulphonic acid sodium.
In a weakly acidic solution, the product has strong glue-precipitating properties and transforms the animal nakedness into valuable, white and full leather.
<I> Example </I> 184 parts of SZ-chloromethylene salicylic acid are boiled in 400 parts of 30% acetic acid with 197 parts of sodium pheriolsulfonate for 6 hours on a reflux condenser. Stirring is of the essence. The contents of the flask are poured into ice water, the new condensation product separating out as a thick resin that slowly hardens. After washing it out with the help of sodium acetate, it is brought into solution with a little water, acidified with acetic acid and can now be used as a tanning agent without further ado.
