摘要： Transition metals may be recovered from a salt-containing mixture containing at least one transition metal compound, salts, and organic compounds by separating from the salt-containing mixture a mixture of the transition metal compound and the salts. This mixture, together with any organic impurities, is introduced into a combustion zone, and the flue gas/salt mixture leaving the combustion zone is quenched with water. The combustion residue, containing the transition metal, is separated from the resulting quench solution, dried, and converted to fresh catalyst.

摘要： A stable and high-solids aqueous dispersion of blocked isocyanates, containing auxiliary solvent, is prepared by (1) preparing a solution of a polyisocyanate mixture of from 20-70% by weight of a blocked, hydrophilically modified polyisocyanate (A) and from 30-80% by weight of a blocked, hydrophobic polyisocyanate (B) in an auxiliary solvent (G) and (2) adding water to this solution, with intensive mixing, in an amount which is such as to give a two-phase system comprising a disperse polyisocyanate phase and a continuous, aqueous phase containing auxiliary solvent. In a preferred embodiment of the invention dispersions are prepared which are virtually free from auxiliary solvent, by first adding a portion of water to the solution (1), substantially removing the auxiliary solvent with intensive mixing and then adding a second portion of water with intensive mixing to the mixture comprising the polyisocyanates (A) and (B) and the first portion of water.
