ABSTRACT:
A process for separating inorganic and organometallic by-products from a mixture comprising at least one organometallic transition metal compound as product and at least one organometallic by-product and at least one inorganic by-product as by-products comprises the stepsA) admixing the mixture comprising the product, the organometallic by-product and the inorganic by-product with a mixture comprising at least one polar organic extractant and water and separating off the undissolved residue,B) washing the residue from step A) with a nonpolar organic extractant or a mixture comprising at least one nonpolar organic extractant and at least one aprotic polar organic solvent andC) drying the residue which has been washed in step B) and comprises the organometallic transition metal compound.
