Carbon dioxide (CO(2)) is an easily available, renewable carbon resource, which has the advantages of being non-toxic, abundant and economical. CO(2) is also attractive as an environmentally friendly chemical reagent, and is especially useful as a phosgene substitute. CO(2) is an "anhydrous carbonic acid" that rapidly reacts with basic compounds. Nucleophilic attack at CO(2) conveniently produces carboxyl and carbamoyl groups. Further reactions of these species with electrophiles lead to the formation of organic carbonates and carbamates. The present article deals with the synthetic technologies leading to organic carbonates using CO(2) as a raw material.

“…(4), has been reported to adequately correlate the water-CO 2 [22], DEC-CO 2 [23], ethanol-CO 2 [24], ethanol-water [25], and CO 2 -ethanol-water [26] both at high and moderate pressures. Furthermore, Pineros et al [27] reported that PRSV describes adequately the binary and ternary subsystems of the DMC-methanol-H 2 O-CO 2 mixture and, thus, the authors used this equation of state to model the quaternary system. Therefore, considering the chemical similarity with the system in this work, PRSV was used to calculate the vapor-phase fugacity coefficient.…”

Enhanced Conversion in the Direct Synthesis of Diethyl Carbonate from Ethanol and CO₂ by Process Intensification

To overcome the low equilibrium conversion in the direct synthesis of diethyl carbonate from ethanol and CO 2 under moderate reaction conditions, the reaction was conducted in a membrane reactor packed with pelletized Cu-Ni:3-1 supported on activated carbon. A SiO 2 /g-Al 2 O 3 commercial membrane and zeolite A membranes synthesized on commercial Al 2 O 3 supports were evaluated in the membrane reactor. Although characterization of the membranes by X-ray diffraction confirmed the presence of a zeolite A layer on the supports, gas permeation and permselectivity tests of ethanol and water evidenced some defects of the synthesized membranes. An increase in conversion with respect to a conventional packed-bed reactor was observed in the membrane reactors prepared on Al 2 O 3 , but equilibrium conversion was not attained. However, with the commercial membrane, the ethanol conversion was higher than the equilibrium conversion.
