摘要：Catalytic procedure for the preparation of an organic carbonate having generalformula (I): wherein R represents a C1-C10 alkyl radical, linear or branched, or a C5-C8cycloalkyl radical; or of a cyclic organic carbonate having general formula (II): wherein R'represents a C2-C5 alkylene radical, linear or branched; including the reacting of analiphatic or cyclo-aliphatic alcohol having general formula (III): or an aliphatic diol havinggeneral formula (IV): wherein R and R' have the meaning described above, with carbonmonoxide and oxygen, in the presence of a catalyst composed of a cobalt(II) or cobalt(III)ion and an organic binder containing at least one oxygen atom, characterized in that theprocess is carried out in the presence of at least one reaction coadjuvant selected fromthe following groups of linear or cyclic compounds: ureas, nitriles, amides,phosphoramides, sulphones, sulphoxides, carbamates.
