<p>Sodium aluminate is presented as a highly active heterogeneous
catalyst able to convert a range of alcohols into the corresponding mixed
carbonate esters, in high yield and under green conditions. The reaction is
carried out using dimethyl carbonate both as a reactant and solvent, at 90°C.
Allylic, aliphatic and aromatic alcohols are converted in good yields. The solid
catalyst is shown to be truly heterogeneous, resistant to leaching, and
