This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.

The invention describes single-site metal catalysts such as Pt single-site centers on powdered oxide supports with a 1,10-phenanthroline-5,6-dione (PDO) or bis-pyrimidyltetrazine (BMTZ) ligand on powdered MgO, Al.sub.2O.sub.3, or CeO.sub.2.

The present disclosure relates to an ionic liquid composition and a process for its preparation. The process of the present disclosure is simple, single pot and efficient process for preparing the ionic liquid composition which is effective in a Friedel Craft reaction like, alkylation reaction, trans-alkylation, and acylation. The present disclosure envisages an ionic liquid composition comprising at least one metal hydroxide; at least one metal halide; and at least one solvent. Also envisaged is a process for preparing an ionic liquid composition. The process comprises mixing in a reaction vessel, at least one metal hydroxide and at least one metal halide in the presence of at least one solvent under a nitrogen atmosphere and continuous stirring followed by cooling under continuous stirring to obtain the ionic liquid composition.
