Description: The subject of the invention is derivative of a new β-ketoimine, which is 4-(3-triethoxysilylpropylimino)-3-ethyl-pentan-2-one and also a method for obtaining this derivative. The invention described in the patent application P.442807 (2022) allows to use of a new derivative as compound that binds metal ions from solution.
The subject of the invention is also a method for obtaining 4-(3-triethoxysilylpropylimino)-3-ethyl-pentan-2-one. The synthesis procedure consisted of the addition of 3-ethyl-pentane-2,4-dione to 3-aminopropyltriethoxysilane in a 1:1 molar ratio of reagents and subsequent elimination of the water molecules by heating the mixture with constant stirring at a temperature from the boiling point of 3-ethyl-pentane-2,4-dione to 100°C for 1 - 2 hours. The obtained product was recrystallized by a known method. The essence of the invention is also the use of a new derivative as a compound that binds metal ions from solutions. The obtained complexes are characterized by high stability, which is why they are of great importance in many fields of technology, e.g. can be used as compounds binding metal ions from solutions in chemical analysis, ion exchange processes, membrane processes, adsorption, solvent extraction, metal separation in hydrometallurgy or catalysts used in industrial organic synthesis.
