Chemical process to manufacture branched-caprolactone

Synthesizing an alkyl-caprolactone includes hydrogenating an alkyl-phenol to yield a first mixture comprising an alkyl-cyclohexanone and an alkyl-cyclohexanol; separating the alkyl-cyclohexanone from the first mixture to yield a first portion of a purified alkyl-cyclohexanone; oxidizing the first portion of the purified alkyl-cyclohexanone to yield a second mixture comprising an alkyl-caprolactone, the alkyl-cyclohexanone, and the alkyl-cyclohexanol; separating the alkyl-caprolactone from the second mixture to yield a third mixture comprising the alkyl-cyclohexanone and the alkyl-cyclohexanol; combining the third mixture and the first mixture in to yield a fourth mixture; separating the alkyl-cyclohexanone from the fourth mixture to yield a second portion of the purified alkyl-cyclohexanone; oxidizing the second portion of the purified alkyl-cyclohexanone to yield a fifth mixture comprising the alkyl-caprolactone, the alkyl-cyclohexanone, and the alkyl-cyclohexanol; separating the alkyl-caprolactone from the fifth mixture; and combining the alkyl-caprolactone from the fifth mixture with the alkyl-caprolactone from the second mixture.
