Definitions
- the invention relates to the use of N-alkyl-beta-alanine derivatives and their salts as anti-corrosion agents with simultaneous cleaning effect.
- Corrosion protection agents must be used to prevent the To suppress corrosion.
- a subsequent one Cleaning step can be worked with an aqueous surfactant solution become. It is usually about multicomponent mixtures of anionic and nonionic surfactants.
- N-alkyl-beta-alanine derivatives used in accordance with the invention are made by converting fatty amines with acrylic acid in inert solvents under known per se Reaction conditions. Depending on the selected stoichiometry of the educts, the mono- or diaddition products.
- the technical reaction mixtures are usually without further isolation of the neutralized the respective pure components with a base or adjusted to higher values in the pH value.
- the fatty amines used are prepared by known processes by reacting fatty acids with NH 3 in the presence of catalysts to give the nitrile and subsequent hydrogenation to give the primary or secondary amine.
- Fatty acids such as Caprylic acid, capric acid, 2-ethylhexanoic acid, lauric acid, Myristic acid, palmitic acid, palmitoleic acid, isostearic acid, Stearic acid, hydroxystearic acid (ricinoleic acid), Dihydroxystearic acid, oleic acid, linoleic acid, petroselinic acid, Elaidic acid, arachic acid, behenic acid and erucic acid, Gadoleic acid as well as those in the pressure splitting of natural fats and oils from technical mixtures such as oleic acid, Linoleic acid, linolenic acid, and in particular rapeseed oil fatty acid, Soybean oil fatty acid, sunflower oil fatty acid, tall oil fatty acid concomitantly. In principle, all fatty acids are also suitable similar chain distribution.
- the iodine number is the amount of iodine, which from 100 g Connection for the saturation of the double bonds added becomes.
- C 8/18 coconut or palm fatty acids Partially hardened C 8/18 coconut or palm fatty acids, rapeseed oil fatty acids, sunflower oil fatty acids, soybean oil fatty acids and tall oil fatty acids, with iodine numbers in the range from approximately 80 to 150 and in particular technical C 8/18 coconut fatty acids are used, where appropriate a selection of cis / trans Isomers such as C 16/18 fatty acid cuts rich in elaidic acid can be advantageous. They are commercially available products and are offered by various companies under their respective trade names.
- the degreasing / corrosion protection behavior can be adjusted by controlling the ratio of the compounds of the general formulas (I) and (II) used. With increased proportions of the compounds of the general formula (II) in which R d is an optionally branched alkyl radical or alkenyl radical with in particular 8 to 14 carbon atoms, optionally containing double bonds, formulations are obtained which, in addition to having sufficient degreasing capacity, provide excellent corrosion protection.
- R a , R b and R c (Na, K or the protonated residue of an amine, preferably a mono-, di- or trialkanolamine), such as, for example, monoethanolamine, diethanolamine, in particular triethanolamine, monoisopropanolamine, diisopropanolamine , Methyldiethanolamine, methylethanol isopropanolamine or mixtures thereof.
- the ratio of Na, K, ammonium to protonated residue an amine can and will fluctuate in wide ranges co-determined by the rest R and the quantitative ratio of Formulas (I) and (II). In any case, it is chosen that the water solubility of the compounds as well as sufficient Cleaning power and corrosion protection guaranteed is.
- the compounds of the general formulas (I) and / or (II) in amounts of approximately 0.1 to approximately 5% by weight, in particular 0.5 to 3 wt .-% used. All can continue on this Field of usual auxiliaries and additives in the known commonly used concentrations are also used such as emulsifiers, foam regulators, Biocides and antioxidants.
- Example 1 0.5 mol of a mixture of Octylamine and stearylamine (1: 2) with 1.0 mole of acrylic acid implemented. It was 0.2 mol in the first step Monoethanolamine and in the second step with 0.78 mol Triethanolamine diluted. After distilling off the Isopropanols the product was dissolved in water and with NaOH adjusted to a pH of 10.
- Example 1 0.5 mol of dodecylamine were used 1.0 mol of acrylic acid reacted. After dilution with 0.08 mol Monoethanolamine and then with 0.9 mol of triethanolamine, The isopropanol was distilled off in water dissolved product adjusted to a pH of 9.0 with KOH.
