| Number | Title | Issue Date |
| 6906229 | Process for hydrolyzing di-isopropyl ether to isopropyl alcohol by catalytic distillation using a solid acid catalyst The invention relates to the production of isopropyl alcohol from di-isopropyl ether by catalytic distillation. The process solves, in particular, problems associated with the Sulfuric Acid Process. ... | 06/14/2005 |
| 5600024 | Enhanced recovery of alcohol from an ether containing stream A process for producing ethyl tertiary butyl ether and for the substantially complete recovery by fractional distillation of the unreacted ethanol contained in an etherification reaction zone product stream as a product along with the ethyl tertiary butyl... | 02/04/1997 |
| 5268515 | Process of preparing an isopropanol and diisopropyl ether oxgenate motor fuel additive Propene is reacted with water in a multi-stage, fluidized bed catalytic reactor to produce an oxygenate motor fuel additive containing a major proportion of isopropanol, a minor proportion of diisopropyl ether, and some water. The molar ratio of water to ... | 12/07/1993 |
| 5191129 | Method of preparing an isopropanol and diisopropyl ether oxygenate motor fuel additive Propene is reacted with water in a multi-stage, fluidized bed catalytic reactor to produce an oxygenate motor fuel additive containing a major proportion of isopropanol (IPA), some diisopropyl ether (IPE) and some water. The molar ratio of water to propen... | 03/02/1993 |
| 4471142 | Process for producing isopropyl alcohol and di-isopropyl ether An improved process for indirect hydration of propylene to form di-isopropyl ether and isopropyl alcohol is provided in which propylene is absorbed in sulfuric acid to form an extract which is withdrawn from the absorbing zone; water in carefully controll... | 09/11/1984 |
| 4267397 | Hydration of olefinic compounds with dilute sulfuric acid and cobalt sulfate Olefinic compounds, and particularly olefinic hydrocarbons, containing from 2 to about 4 carbon atoms may be subjected to a direct hydration process utilizing a dilute aqueous sulfuric acid to treat the olefin at reaction conditions which will include a t... | 05/12/1981 |
