    Abstract: Continuous production of 5-alken-2-one or 3,5-alkadien-2-one derivatives (I) by reacting a 1-alken-3-ol or 1-alkyn-3-ol derivative (II) with an alkyl acetoacetate (III) in a fractionation column to form an acetoacetate and alcohol involves (i) removing the alcohol and (ii) contacting the acetoacetate with catalyst in the lower part or bottom of the column to form (I). Continuous production of unsaturated ketones of formula (I) by reacting an unsaturated alcohol of formula (II) with an alkyl acetoacetate of formula (III) in the presence of an organoaluminum catalyst is carried out by: (a) reacting (II) with (III) on the plates of a fractionation column to form the acetoacetate of (II) and an alcohol of formula R OH; (b) removing the alcohol in the overhead stream from the column; (c) contacting the acetoacetate of (II) with the catalyst in the lower part or bottom of the column to form (I) and CO2; (d) removing the CO2 in the overhead stream from the column; and (e) withdrawing (I) in the bottoms stream from the column. R = 1-4C alkyl; R = 1-37C (un)saturated aliphatic hydrocarbyl (optionally substituted by methoxy groups), 4-12C cycloalkyl or 5-30C cycloalkylalkyl; and R = 1-5C alkyl.

    Abstract: Preparation of unsaturated methyl ketones(I), from an unsaturated alcohol(II) and alkyl acetoacetate(III) in the presence of an organo-aluminum catalyst(IV) comprises: (a) supplying (II) and (IV) to a reactor with a distillation column, (b) making temperature to be 170-250 degrees C under elevated pressure, (c) dosing the mixture with (III) and (d) maintaining a constant (III) content of 0.1-10 wt.% during the reaction. Preparation of unsaturated ketones of formula (I) involves reaction of an unsaturated alcohol of formula (II) with an alkyl acetoacetate of formula (III), in presence of 0.1-5 mol. % (based on (II)) of an organo-aluminum compound catalyst (IV), with elimination and distillative separation of the alcohol R3OH formed in the reaction, in a reactor system provided with a distillation column. Reaction is carried out by: (a) supplying (I (which boils at less than 140 degrees C), without a solvent, and (IV) to the reaction vessel, (b) adjusting the temperature to a value as constant as possible in the range 170-250 degrees C under elevated pressure, (c) dosing the mixture with (III) and (d) maintaining a (III) content as constant as possible in the range 0.1-10 wt. % during the reaction. Dotted line = optional bond; R1 = Me or Et; R2, R3 = 1-4C alkyl.

    Abstract: An assembly to make a liquid made of ingredients including gas which may react with each other. The mixing chamber (1) is formed of a symmetrical outer mantle and two end walls (3, 5). Mixer paddles rotate within the chamber, driven by a motor. The novelty is that the mantle has a separate inlet (8, 9) for each ingredient and an outlet (10) for the mixing product; further that there is a flowpath between the two ends walls (3, 5) formed by a circular passage (17). USE/ADVANTAGE - The unit mixes ingredients including gas which may react together. The mixer is of simple construction and makes a very homogenous and stable produce with steady output.

    Abstract: A process for the purification of crude terephthalic acid comprises catalytic hydrogenation using a catalyst material (I) comprising a ca bon supported hydrogenation metal whereby the carbon support comprises carbon fibers. Independent claims are included for: (1) the catalyst material (I) whereby the carbon support has a BET surface area of less than 500 Micro 2>/g; (2) a reactor (II) containing a flat catalyst material in the form of cloth, textile and/or felt comprising a hydrogenation metal applied to carbon fibers and having at least two edges opposite to each other to which the catalyst material is stably affixed or containing the catalyst material in the form of parallel fibers or bands; and (3) a process for the selective hydrogenation of carbon-carbon double or triple bonds and/or hydrogenatable functional groups using the catalyst material (I) or reactor (II).
