Abstract: A process for oxidizing a starting material with an oxidizing agent to obtain a product, which comprises carrying out the oxidation in a reaction apparatus which has a bottom region at the lower end, a top region at the upper end and a reaction zone between the top region and the bottom region, maintaining the reaction mixture in the boiling state in the reaction zone, and introducing oxidizing agent into the reaction zone in at least two substreams.

Abstract: Production of saturated carbonyl compounds (I) by selective liquid-phase hydrogenation of alpha , beta -unsaturated carbonyl compounds (II) is carried out in a packed bubble column with the product recycled and by circulating hydrogen gas. Production of saturated carbonyl compounds of formula R1-CH(R2)-CH(R3)-C(R4)=O (I) by selective liquid-phase hydrogenation of alpha , beta -unsaturated carbonyl compounds of formula R1-C(R2)=C(R3)-C(R4)=O (II) in the presence of a particulate palladium and/or rhodium catalyst and a base is carried out in a packed bubble column with the product recycled and by circulating hydrogen gas. R1 = H or an organic group; R2-R4 = H or 1-4C alkyl.

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: A process for carrying out exothermic reactions comprises (a) addition reaction of an organomagnesium halide of formula RMgX with a carbonyl compound; and (b) hydrolysis of the addition product in a solvent or solvent mixture, in which much of the heat liberated in the reaction is removed by evaporation of the solvent. R = 1-6C alkyl, alkenyl or alkynyl, or aryl; X = Cl, Br or I.
