Description

Es ist bekannt Benzin/Alkohol-Gemische als Treibstoffe für Otto­ motoren, insbesondere Automobile, zu verwenden. Solche Treibstoffe können z.B. aus 85-99 Volumenanteilen Benzin (Kohlenwasserstoffen) und 15-1 Volumenanteilen Alkohol, wie Methanol und/oder Aethanol, bestehen. Weiter ist es möglich, Alkohol oder eine Mischung, die vor­ wiegend aus Alkohol, z.B. Methanol, besteht, oder der z.B. bis zu 40 Volumenanteile an Kohlenwasserstoffen beigemischt sind, als Treibstoffe zu verwenden. Solche Mischungen enthalten nur wenig Wasser (1,5-4%). Trotzdem verursachen solche Alkohole oder deren Mischungen mit Kohlenwasserstoffen Korrosionsprobleme, z.B. an Eisen-, Zink-, Magnesium und Aluminiumteilen und Buntmetallen, insbesondere an Bau­ teilen, z.B. Armaturen, von Automobilen, Zapfsäulen und Treibstoff­ tanks. Dies ist u.a. bedingt durch den Gehalt des Alkohols an Ameisensäure und Essigsäure, bedingt durch deren technische Her­ stellung.It is known gasoline / alcohol mixtures as fuels for Otto motors, especially automobiles. Such fuels can e.g. from 85-99 parts by volume of gasoline (hydrocarbons) and 15-1 parts by volume of alcohol, such as methanol and / or ethanol, consist. It is also possible to use alcohol or a mixture before predominantly from alcohol, e.g. Methanol, or e.g. up to 40 parts by volume of hydrocarbons are added as To use fuels. Such mixtures contain little water (1.5-4%). Nevertheless such alcohols or their mixtures cause with hydrocarbon corrosion problems, e.g. on iron, zinc, Magnesium and aluminum parts and non-ferrous metals, especially in construction share, e.g. Faucets, from automobiles, petrol pumps and fuel tanks. This includes due to the alcohol content Formic acid and acetic acid, due to their technical origin position.

Aus der DE-OS 34 33 554 ist es bekannt, diese Korrosion durch Verwendung von bestimmten Phosphorsäureestern zu verringern. Solche Phosphor­ säureester können jedoch nicht bei Treibstoffen eingesetzt werden, die für Automobile benutzt werden, die mit Katalysatoren ausgerüstet sind. Es besteht daher weiterhin Bedarf für phosphorfreie Korrosions­ inhibitoren, welche die in Alkohol enthaltenden Treibstoffen auf­ tretende Korrosion verhindern.From DE-OS 34 33 554 it is known to use this corrosion of certain phosphoric acid esters. Such phosphorus However, acid esters cannot be used in fuels used for automobiles equipped with catalytic converters are. There is therefore still a need for phosphorus-free corrosion inhibitors, which the fuels contained in alcohol Prevent emerging corrosion.

Die Erfindung betrifft phosphorfreie Korrosionsinhibitoren für Treib­ stoffe, enthaltend eine Mischung von Benzotriazol und Tolyltriazol, Natriumboroheptonat, ein Aethylenoxydanlagerungsprodukt von primären oder sekundären Aminen, Aethylenglykol und Methanol oder Aethanol. The invention relates to phosphorus-free corrosion inhibitors for propellants substances containing a mixture of benzotriazole and tolyltriazole, Sodium boroheptonate, an ethylene oxide addition product of primary or secondary amines, ethylene glycol and methanol or ethanol.  

Als Amin wird vorzugsweise Talgaminopropylamin eingesetzt und mit 25-30 Mol Aethylenoxyd umgesetzt.Talgaminopropylamine is preferably used as the amine and with 25-30 moles of ethylene oxide reacted.

Diese Korrosionsinhibitoren lassen sich einwandfrei in Treibstoffen lösen und haben eine korrosionsverhindernde Wirkung, die denen der phosphorhaltigen Inhibitoren vergleichbar ist. Sie können insbeson­ dere eingesetzt werden bei Treibstoffen, die für Automobile ver­ kauft werden, welche mit Katalysatoren ausgerüstet sind. Solche Treibstoffe sind auch als "Euro-Super" bekannt und enthalten etwa 90% Kohlenwasserstoffe, 5% Aethanol, 3% Methanol und 2% tert. Butanol. In solchen Treibstoffen werden die Korrosionsinhibitoren in Mengen von 50-300 ppm (bezogen auf den Alkoholanteil), bevorzugt in Mengen von 60-120 ppm eingesetzt.These corrosion inhibitors can be perfectly used in fuels dissolve and have a corrosion-preventing effect that those of phosphorus-containing inhibitors is comparable. You can in particular are used for fuels used for automobiles be bought, which are equipped with catalysts. Such Fuels are also known as "Euro Super" and contain about 90% hydrocarbons, 5% ethanol, 3% methanol and 2% tert. Butanol. In such fuels, the corrosion inhibitors are in quantities from 50-300 ppm (based on the alcohol content), preferably in quantities of 60-120 ppm used.

Die Korrosionsinhibitoren enthalten die verschiedenen Wirkstoffe vorzugsweise in folgenden Anteilen: eine synergistische Mischung von Benzotriazol und Tolyltriazol in einer Menge von 10-15 Gew.-%, Natriumboroheptonat in einer Menge von 5-6 Gew.-%, ein Anlagerungsprodukt von Aethylenoxyd an Talgamino­ propylamin (25-30 Mol Aethylenoxyd pro Mol Amin), das auch eine dispergierende Wirkung hat, in einer Menge von 3 bis 12 Gew.-% und Aethylenglykol, das auch als Lösungsmittel dient, in einer Menge von 35 bis 45 Gew.-%. Alle in Methanol bzw. Aethanol gelösten Wirkstoffe machen zusammen eine Menge von 60 bis 65 Gew.-% aus.The corrosion inhibitors contain the various active ingredients preferably in the following proportions: a synergistic blend of benzotriazole and tolyltriazole in an amount of 10-15% by weight, sodium boroheptonate in an amount of 5-6 wt .-%, an adduct of ethylene oxide with Talgamino propylamine (25-30 moles of ethylene oxide per mole of amine), which is also a has a dispersing effect in an amount of 3 to 12 wt .-% and Ethylene glycol, which also serves as a solvent, in an amount of 35 to 45% by weight. All active ingredients dissolved in methanol or ethanol together make up an amount of 60 to 65% by weight.

Die verschiedenen Bestandteile der Korrosionsinhibitoren können ein­ fach miteinander vermischt werden. Um eine klare Lösung der Wirk­ stoffe in möglichst wenig Methanol oder Aethanol zu erhalten, empfiehlt es sich, zunächst nur einen Teil der Mischung von Benzotriazol und Tolyltriazol (z.B. 8 Teile und 2 Teile), von Natriumboroheptonat (4 Teile) und Aethylenglykol (30 Teile) in wasserfreiem Methanol oder Aethanol (30 Teile) zu lösen, das Aethylenoxydanlagerungsprodukt von Talgaminopropylamin zu dieser Grundmischung zu geben und weitere Anteile der vorher genannten Wirkstoffe sowie Methanol oder Aethanol bis zur gewünschten Konzentration dazuzugeben.The various components of the corrosion inhibitors can to be mixed together. To a clear solution of the active Preserving substances in as little methanol or ethanol as possible is recommended it, initially only part of the mixture of benzotriazole and Tolyltriazole (e.g. 8 parts and 2 parts) from sodium boroheptonate (4 parts) and ethylene glycol (30 parts) in anhydrous methanol or Dissolve ethanol (30 parts), the ethylene oxide addition product of  Add tallow aminopropylamine to this base mix and more Proportions of the previously mentioned active ingredients as well as methanol or ethanol add to the desired concentration.
