Description
Die Erfindung betrifft ein Verfahren zur Verhinderung der Korrosion von Kupfer durch Essigsäure.The invention relates to a method for preventing the corrosion of copper by acetic acid.
Aus der US-PS 3231507 ist bekannt, korrodierenden Hüssigkeiten Propargylalkohol bzw. Propinol als Korrosionsinhibitor zuzusetzen.From US-PS 3231507 it is known to use corrosive liquids as propargyl alcohol or propynol Add corrosion inhibitor.
Die Korrosion von Kupfer in Essigsäure kann so jedoch nicht verhindert werden.However, this cannot prevent the corrosion of copper in acetic acid.
Gegenstand der Erfindung ist ein Verfahren zur Verhinderung der Korrosion von Kupfer durch Essigsäure, welches dadurch gekennzeichnet ist, daß man der Essigsäure 0,01 bis 10 Gew.-%, vorzugsweise 0,1 bis 1,0 Gew.-% Acetol bzw. Acetolester organischer Carbonsäuren zusetzt.The invention relates to a method for preventing the corrosion of copper by acetic acid, which is characterized in that the acetic acid 0.01 to 10 wt .-%, preferably 0.1 adds up to 1.0% by weight of acetol or acetol ester of organic carboxylic acids.
Die Essigsäure liegt in wäßriger Lösung in beliebiger Verdünnung vor.The acetic acid is in an aqueous solution in any dilution.
Acetol kann durch Hydratation von Propargylalkohol nach Reppe in Gegenwart von Hg SO4Zh2SO4 oder Jurch Reaktion an einem mit Hg-Salzen beladenen Ionenaustauscher hergestellt werden.Acetol can be produced by hydration of propargyl alcohol according to Reppe in the presence of Hg SO 4 Zh 2 SO 4 or by reaction on an ion exchanger loaded with Hg salts.
Eine weitere bekannte Herstellungsmethode ist die Addition von Methanol an Propargylalkohol, wobei zunächst 2,5-Dimethyl-2,5-dimethoxy-dioxan-l,4 entsteht, welches dann mit Wasser zu Acetol und Methanol gespalten werden kann. (Vgl. UUmann's Enzyklopädie der technischen Chemie, 14. Band, 3. Auflage, 1963.)Another known production method is the addition of methanol to propargyl alcohol, wherein initially 2,5-dimethyl-2,5-dimethoxy-dioxane-1,4 is formed, which then with water to acetol and methanol can be split. (See UUmann's Encyclopedia of Technical Chemistry, Volume 14, 3rd Edition, 1963.)
Als Acetolester organischer Carbonsäuren kann man in dem erfindungsgemäßen Verfahren Ester aliphatischer
Carbonsäure, welche 2, 3, 4, 5, 6 bzw. 7 Kohlenstoffatome aufweisen, zusetzen. Dabei können
sowohl die Ester von unverzweigten als auch verzweigten Carbonsäuren verwendet werden.
Derartige Ester können demnach beispielsweise mit Essigsäure, Propionsäure, n-Buttersäure, i-Buttersäure,
n-Valriansäure bzw. n-Capronsäure gebildet werden.In the process according to the invention, esters of aliphatic carboxylic acids which have 2, 3, 4, 5, 6 or 7 carbon atoms can be added as acetol esters of organic carboxylic acids. Both the esters of unbranched and branched carboxylic acids can be used here.
Such esters can accordingly be formed, for example, with acetic acid, propionic acid, n-butyric acid, i-butyric acid, n-valric acid or n-caproic acid.
In einer bevorzugten Ausführungsform können Acetolester der organischen Säuren Propionsäure, n-Buttersäure, i-Buttersäure oder Capronsäore eingesetzt werden.In a preferred embodiment, acetol esters of the organic acids propionic acid, n-butyric acid, i-Butyric acid or Caproic acid can be used.
Auch ein Gemisch dieser verschiedenen Acetolester untereinander oder/und mit Acetol kcan verwendet werden.A mixture of these different acetol esters with one another and / or with acetol can also be used will.
Das erfindungsgemäße Verfahren wird anhand der folgenden Beispiele näher erläutert und beschrieben:The method according to the invention is explained and described in more detail using the following examples:
Ein Kupferblech wird in 80% Essigsäure am Rückfluß gekocht. Die zu untersuchenden Zusätze werden in einer Menge von 0,6 Gew.-% der Essigsäure zugesetzt. A copper sheet is refluxed in 80% acetic acid. The additives to be investigated are added in an amount of 0.6% by weight of the acetic acid.
