TL;DR: In this article, a process for the production of aliphatic alcohol by the direct hydration of an olefinic hydrocarbon was described, and the process was directed to produce isopropyl alcohol from a water-rich hydration zone effluent stream.
Abstract: A process is disclosed for the production of aliphatic alcohol by the direct hydration of an olefinic hydrocarbon. The process is directed to the production of isopropyl alcohol. The process includes the recovery of the alcohol from a water-rich hydration zone effluent stream by countercurrent liquid-liquid extraction against a paraffinic solvent. The solvent is derived from paraffins originally admixed with the olefin-containing feed stream, and the raffinate stream comprises water which is recycled in the process. Expensive product fractionation is eliminated in the production of a fuel grade isopropyl alcohol.

30 Dec 1988TL;DR: In this article, a process for converting light olefin(s) to alcohol, ether, or a mixture of alcohol and ethers is described, which is applicable to the hydration of a propylene-containing feed, for example, a refinery FCC stream containing a substantial amount of propylene.
Abstract: A process is disclosed for converting light olefin(s) to alcohol(s), ether(s) or a mixture of alcohol(s) and ether(s) which comprises contacting a feed containing at least one light olefin with water in the vapour and/or liquid phase under olefin hydration conditions in the presence of acidic zeolite Beta as catalyst to produce said alcohol(s), ether(s) or mixture thereof. The process is especially applicable to the hydration of a propylene-containing feed, for example, a refinery FCC stream containing a substantial amount of propylene, to provide a mixture of isopropyl alcohol (IPA) and diisopropyl ether (DIPE) which is particularly useful as an octane improver for gasoline.

11 Aug 2011TL;DR: In this paper, an isopropyl alcohol-producing Escherichia coli, which comprises: a system that produces isoprol alcohol together with the deactivation of the transcription regulator GntR; and a coenzyme group having an enzymatic activity manifestation pattern that maintains or reinforces the isoprocessyl alcohol production that accompanies the activation of Gntr, is presented.
Abstract: Provided is an isopropyl alcohol-producing Escherichia coli, which comprises: a system that produces isopropyl alcohol together with the deactivation of the transcription regulator GntR; and a coenzyme group having an enzymatic activity manifestation pattern that maintains or reinforces the isopropyl alcohol production that accompanies the deactivation of GntR. Also provided is a method for producing isopropyl alcohol, which includes the production of isopropyl alcohol from a plant-derived starting material using this isopropyl alcohol-producing Escherichia coli. Further provided is a method for producing acetone, which includes bringing the isopropyl alcohol obtained by the above-mentioned production method into contact with a compound oxide that contains zinc oxide and at least one oxide of group 4 of the Periodic Table of Elements and that has been prepared by coprecipitation. Additionally provided is a method for producing propylene, which includes bringing the isopropyl alcohol and acetone obtained by the above-mentioned production methods into contact with a solid acid substance and a hydrogenation catalyst containing Cu as the catalysts.
