| titleOfInvention | Method of making trimethylene carbonate |
| abstract | The present invention comprises the steps of reacting phosgene with 1,3-propanediol in vapor form, providing a combination of temperature and pressure where trimethylene carbonate is present in the vapor phase, reacting 1,3-propanediol with phosgene Providing a residence time sufficient to produce trimethylene carbonate, condensing the trimethylene carbonate vapor, and isolating the condensed trimethylene carbonate. The method has the advantage that it does not require the use of catalysts and the associated recovery and / or regeneration or treatment of catalyst residues. |
