Organic carbonates are used in the manufacture of a large number of other industrially important products, minly polyurethanes and polycarbonates. Tey are employed in the manufacture of pharmaceutical products, hrbicides, psticides, eectrolytic fluids, plyimide films, ec., in addition to being used as solvents and fuel additives (3). Tey are environmentally benign, tey are replacing toxic organic solvents, mthylating agents and carbonating agents such as methyl halides, dmethyl sulphate and phosgene (3). Other variations of organic carbonates also exist. Fr instance, aiphatic polycarbonates are biodegradable and hence are medically Tey are also used as matrix materials, termoplastic additives and films in addition to being used for the production of industrially important materials such as specialty polyurethanes (4).
Gycerol based carbonate polymers also have a wide range of industrial, parmaceutical and chemical applications. Plycarbonate esters and other carbonate polymers are used as antibacterial compounds and fluorescent tags in the biomedical field (5). Posgenation technique, oidative carbonylation of phenols and alcohols, raction of urea with phenols and alcohols, raction of carbon dioxide and oxiranes, ad transformation of inorganic metal carbonates of the most commonly used methods for synthesis of organic carbonates.
Te aim of this paper is to study the development of catalysts in the synthesis of organic carbonates. Terefore, tis paper will mainly focus on the types of catalysts used and the yield of organic carbonates while briefly discussing the various synthesis procedures. Hwever, i will be difficult to outline the development of catalysts for all organic carbonates over time. Terefore, t narrow down the research, te paper focuses on the catalysts used in the synthesis of carbonate DC is the simplest organic carbonate and is one of the most industrially useful carbonates (2).
I is also used for the synthesis of many other organic carbonates, aart from being used as an organic solvent and fuel additive. I is not ecotoxic and hence, i an environmentally benign compound. Te report first provides a brief summary of catalysts used in the synthesis of various organic carbonates and the synthesis procedures. I then goes on to explain the development of catalysts for DMC. ..
