The present invention discloses a newly high-efficiency method for co-production of carboxylic acid and ε-caprolactone based on the aerobic oxidation, that is, under the developed catalytic system, the aldehyde is oxidized to corresponding carboxylic acid while cyclohexanone is oxidized to ε-caprolactone, realizes the co-production of carboxylic acid and ε-caprolactone. The salient features of this method include the use of cheap and readily available substrates, mild reaction conditions, environmentally friendly, and easy operation. It can realize the co-production of carboxylic acid and high value-added ε-caprolactone.

A calcium carboxylate is prepared by reacting water, calcium oxide, and a compound of formula (I):

##STR00001##

wherein R is a C.sub.1-C.sub.3 alkyl and R.sub.1 is a C.sub.1 or C.sub.2 alkyl. The reaction solution is heated to remove an amount of a co-product from the reaction solution. The calcium carboxylate may be recovered in a solid form from the reaction solution.

Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.

Disclosed herein are methods for the recovery of target bio-base carboxylic acid products using a sorption-based technology with a mixed elution solvent optimized for minimized downstream distillation energy input. The sorption-based technology includes absorbing the targeted bio-base carboxylic acid products onto a non-ionic resin and eluting the targeted bio-base carboxylic acid products with a mixed elution solvent. The mixed elution solvent includes a first solvent and a second solvent. The first solvent has a boiling point that is lower than the targeted bio-base carboxylic acid products and the second solvent is selected from the group consisting of a phosphine oxide or tertiary amine.
