    Abstract: The present application relates to an apparatus and process for producing dimethyl carbonate, in particular a system (apparatus or process) for DMC synthesis without the need of using a dehydrating agent. More particularly, the feed mixture for the process can be selected from the following options: a) carbon monoxide, methanol and flue gas from the process, b) synthesis gas without CO 2 and flue gas from the process, c) synthesis gas with CO 2 and added synthesis gas from purified flue gas from the process. The process uses a catalyst cluster comprising a specific combination of different groups of heterogeneous catalysts wherein each group has a different function. Also the invention relates to an apparatus comprising a specific combination of heterogeneous catalysts for applying different routes to produce dimethyl carbonate from each feed mixture option, on continuous basis.

    Abstract: A process for producing a carbonic ester which comprises the steps of: (1) reacting an organometallic compound having a metal-oxygen-carbon bond with carbon dioxide to obtain a reaction mixture containing a carbonic ester formed by the reaction; (2) separating the carbonic ester from the reaction mixture to obtain a liquid residue; and (3) reacting the liquid residue with an alcohol to form an organometallic compound having a metal-oxygen-carbon bond and water, removing the water from the organometallic compound, and recovering the organometallic compound obtained in the step (3) in order to recycle it to the step (1).

    Abstract: The present invention provides a process for producing : a compound represented by XOR 2 ; a dialkyl tin dialkoxide compound having one tin atom, two Sn-R 1 bonds and two Sn-OR 2 bonds; and/or a tetraalkyl dialkoxy distannoxane compound having one Sn-O-Sn bond, in which each tin atom of the tetraalkyl dialkoxy distannoxane compound has two Sn-R 1 bonds and one Sn-OR 2 bond, the process comprising reacting in the absence of a catalyst at least one alkyl tin compound selected from the group consisting of i) and ii) below:
    i) a dialkyl tin compound having one tin atom, two Sn-R 1 (wherein R 1 represents an alkyl group) bonds, and two Sn-OX bonds (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); and
    ii) a tetraalkyl distannoxane compound having one Sn-O-Sn bond, in which each tin atom of the tetraalkyl distannoxane compound has two Sn-R 1 bonds and one Sn-OX bond (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); and

    a carbonic acid ester represented by R 2 OCOOR 2 (wherein R 2 represents a linear or branched, saturated or unsaturated hydrocarbon group, a hydrocarbon group having a saturated or unsaturated cyclic hydrocarbon substituent, or a Y-CH 2 - group (wherein Y represents an alkyl polyalkylene group, an aromatic group or a cyclic saturated or unsaturated alkylene ether group)), and/or
    an alcohol represented by R 2 OH (wherein R 2 is the same as defined above).
