Abstract: Processes for reducing the amount of a gaseous iodide-containing impurity present in a recycle gas stream used in the production of ethylene oxide, in particular an alkyl iodide impurity, are provided. Processes for producing ethylene oxide, ethylene carbonate and/or ethylene glycol, and associated reaction systems are similarly provided.

Abstract: A process for the preparation of an alkylene glycol from an alkene is provided, along with an absorber apparatus. The process comprises: supplying a gas composition to an absorber comprising a column of vertically stacked trays, wherein each of the vertically stacked trays comprises: a perforated gas-liquid contacting member or members, a liquid inlet area, an outlet weir extending vertically above a surface of the tray at an opposite end of the tray from the liquid inlet area and having a height of at least 200 mm and at most 1500 mm, and a downcomer element which, in cooperation with an inner surface of a wall of the column, forms a downcomer for the passage of liquid downwardly to the liquid inlet area of an adjacent vertically stacked tray below, and allowing the gas composition to pass upwards through the alkylene oxide absorber.

Abstract: A method for producing acetophenone comprising: treating one or more alkylbenzenes comprising s-butylbenzene to produce a feed comprising phenol and acetophenone; separating a crude phenol stream from the feed under crude phenol separation conditions effective to produce a crude phenol heavies; and, separating an acetophenone stream directly from the crude phenol heavies under azeotropic distillation conditions.

Abstract: A process for cleaving an oxidation product comprising s-butyl benzene hydroperoxide and/or cumene hydroperoxide which reduces the production of non-recoverable by-products from dimethylbenzyl alcohol (DMBA) and ethyl methyl benzyl carbinol (EMBA).

Abstract: A process for producing phenol and methyl ethyl ketone (MEK).

Abstract: Improved processes for oxidizing alkylbenzene(s) to produce phenol and ketone product(s) using neutralizing base.

Abstract: A process for separating linear alpha olefins from a feedstock containing linear alpha olefins, saturated hydrocarbons, internal olefins, branched olefins, and alcohols, in particular, from a Fisher-Tropsch stream is provided.

Abstract: Improved hydrogenation catalysts consisting essentially of reduced or at least partially reduced ruthenium and tin on a refractory oxide support which is insoluble in aqueous acid. Such catalysts are very durable and exhibit high conversion rates in aqueous acidic solution hydrogenation of hydrogenatable precursors (e.g. maleic acid, succinic acid, gamma-butyrolactone etc.) and high selectivity for their conversion to 1,4-butanediol and gamma-butyrolactone and their mixtures.
