Separation of Vapor Crude Alcohol Product

Номер: US20120010436A1

Автор: Adam OROSCO, David Lee, Lincoln Sarager, Radmila Jevtic, Trinity Horton, Victor J. Johnston

Принадлежит: Celanese International Corp

Recovery of alcohol, in particular ethanol, by separating a vapor crude alcohol product obtained from the hydrogenation of acetic acid using a low energy process. The vapor crude ethanol product is separated in a column to produce a distillate stream comprising ethanol and at least one non-condensable gas. The vapor crude ethanol product may pass through a membrane before the first distillation column to separate the at least one non-condensable gas from the ethanol. The ethanol product is subsequently recovered from the distillate stream.

This invention provides an integrated two stage economical process for the production of vinyl acetate monomer (VAM) from acetic acid in the vapor phase. First, acetic acid is selectively hydrogenated over a hydrogenating catalyst composition to form ethylene either in a single reactor zone or in a dual rector zone wherein the intermediate hydrogenated products are either dehydrated and/or cracked to form ethylene. In a subsequent second stage so formed ethylene is reacted with molecular oxygen and acetic acid over a suitable catalyst to form VAM. In an embodiment of this invention reaction of acetic acid and hydrogen over a hydrogenation catalyst and subsequent reaction over a dehydration catalyst selectively produces ethylene, which is further mixed with acetic acid and molecular oxygen and reacted over a supported palladium/gold/potassium catalyst.

Also disclosed is a process for preparing an unsaturated alcohol composition, where a metathesis derived hydrocarbyl carbonyl compound is reacted in the presence of a silane compound, an organic solvent, and a catalyst system prepared from a metallic complex and a reducing agent. This mixture is then hydrolyzed with a metallic base, and then mixed with organic solvent. The resultant mixture is then separated, washed, dried, and/or purified to produce the unsaturated alcohol composition. The unsaturated alcohol derivatives are useful in many end-use applications, including, for example, lubricants, functional fluids, fuels, functional additives for such lubricants, functional fluids and fuels, plasticizers, asphalt additives, friction reducing agents, plastics, and adhesives.

Method For Producing Beta-Fluoroalcohol

Номер: US20130303774A1

Автор: Akihiro Ishii, Mari Imamura, Takashi Ootsuka, Takehisa Ishimaru

Принадлежит: Central Glass Co Ltd

A production method of a β-fluoroalcohol includes performing a reaction of an α-fluoroester with hydrogen gas (H 2 ) in the presence of a specific ruthenium complex (i.e. a ruthenium complex of the general formula [2], preferably a ruthenium complex of the general formula [4]). This production method can employ a suitable hydrogen pressure of 1 MPa or less by the use of such a specific ruthenium complex and does not require a high-pressure gas production facility when put in industrial practice. In addition, this production method can remarkably reduce the amount of catalyst used therein (to e.g. a substrate/catalyst ratio of 20,000) in comparison to the substrate/catalyst ratio conventional reduction of α-fluoroalcohol. It is possible by these reduction in hydrogen pressure and catalyst amount to largely reduce the production cost of the β-fluoroalcohol.
