摘要： 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.

摘要： The present invention is a separation process for producing a methanol, ethanol and/or dimethyl ether stream from a first stream containing C3+ hydrocarbons. The first stream comprises C3+ hydrocarbons, methanol, ethanol and/or dimethyl ether. The process comprises the step of passing the first stream through an adsorbent bed having a crystalline microporous material that preferentially adsorbs methanol, ethanol and/or dimethyl ether over the C3+ hydrocarbons.

摘要： A process is disclosed for producing α-methylstyrene, acetone, and phenol wherein the amount of α-methylstyrene produced may be controlled by selectively converting a portion of the cumene hydroperoxide to dimethyl phenyl carbinol, the hydrated form of α-methylstyrene. The dimethyl phenyl carbinol thus produced will lead to increased production of α-methylstyrene upon dehydration in the acid cleavage unit of the phenol plant. By controlling the fraction of the cumene hydroperoxide reduced to dimethyl phenyl carbinol, the amount of α-methylstyrene produced in the plant can be continuously set to meet the demand of the market for α-methylstyrene. Also disclosed is a non-acidic catalyst for reduction of cumene hydroperoxide.
