Category: thiazole. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2,6-Dimethyl-3,5-heptanedione, is researched, Molecular C9H16O2, CAS is 18362-64-6, about A cyclic process on the recovery of copper from metal-sludge by solvent extraction.

Cu in sludge was leached with NH3 solution, and the leach solution was extracted with di-isobutyryl methane [18362-64-6] in toluene. The Cu in the organic solvent was stripped with H2SO4, and recovered by electrolysis of the saturated CuSO4 solution The leach solution, the extracting reagent, and H2SO4 were recycled. Recovery of Cu from sludge was 90% and recovery from leach solution was 99%.
