SDS of cas: 18362-64-6. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2,6-Dimethyl-3,5-heptanedione, is researched, Molecular C9H16O2, CAS is 18362-64-6, about Effect of substituents on the distribution coefficients of alkyl-substituted β-diketones and their copper and iron chelates. Author is Koshimura, Hideo; Okubo, Teiji.
A series of alkyl-substituted β-diketones consisting of acetylacetone, dipropionylmethane, diisobutyrylmethane, dipivaloylmethane, dibutyrylmethane, divalerylmethane, dicaproylmethane and diisovalerylmethane was studied to establish the effect of substituents on the extraction constants and the acid dissociation constants The logarithm of the distribution coefficients of the β-diketones and of their Cu(II) and Fe(III) chelates was a linear function of the number of C atoms in the mol. The distribution coefficient increased by a factor of 4 for each addnl. C atom.
