Low corrosive integrated process for preparing dialkyl carbonates |
| abstract |
An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a halogen-free carbonation catalyst to provide a corresponding cyclic carbonate and the cyclic carbonate is then reacted with an aliphatic monohydric alcohol in the presence of the carbonation catalyst and/or a transesterification catalyst and recycling the carbonation catalyst to provide a corresponding dialkyl carbonate and diol, wherein the dialkyl carbonate product exhibits a halogen concentration of about 5 ppm or less. |
