A composition and processes for producing the composition are provided. The composition comprises titanium chelates having the formulae of TiXm(OR)4-m, TiXm(OR)(4-m)/2(OR1)(4-m)/2, and TiXm(OR1)4-m in which X is a radical derived from a chelating agent such as, for example, a diketone, a diester, a ketoester, or combinations of two or more thereof; m is a number from about 1.5 to about 2.5; each R and R1 is independently an alkyl group containing from 1 to about 10 carbon atoms per radical; and R1 differs from R. The process can comprise contacting at least one tetraalkyl titanates with a chelating agent to produce a product mixture comprising a titanium chelate and an alcohol, substantially removing the alcohol to produce an alcohol-reduced titanium chelate, optionally contacting the alcohol-reduced titanium chelate with a second, and further optionally reducing the alcohol content of the titanium.
