| titleOfInvention | Preparation of urethane and carbonate products |
| abstract | The present invention provides a process for preparing urethanes and carbonates from an amine or an alcohol, carbon dioxide and a hydrocarbyl halide. The amine or alcohol is reacted with carbon dioxide in a suitable solvent system and in the presence of a base selected from the group consisting of a phosphazene compound and a mixture of a phosphazene compound and an organic, nitrogenous base, to form the ammonium carbamate or carbonate salt which is then reacted in a polar aprotic solvent with a hydrocarbyl halide. Polymer products can also be prepared utilizing this process or utilizing the resulting urethanes and carbonates under standard polymerization conditions. |
