    Abstract: Preparation of unsaturated ketones by reaction of the corresponding alpha , beta -unsaturated alcohol with an alkyl acetoacetate compound in the presence an organo-aluminum catalyst at constant temperature, with separation and continuous removal of CO2 and alcohol formed. Preparation of unsaturated ketones of formula (I) by reaction of the corresponding alpha , beta -unsaturated alcohol of formula (II) with an alkyl acetoacetate compound of formula (III) in the presence of 0.1-5 mole% (based on (III)) of an organo-aluminum catalyst with separation and continuous distillative removal of CO2 and alcohol of formula R3OH formed during reaction, in a reactor containing a fractionation column, where: (A) (II) is added to the reaction mixture together with the organic catalyst without additional solvent and (III) is then added to this mixture; (B) the reaction temperature is kept constant between 175-220 degrees C; (C) the content of (III) is kept at a constant level between 0.1-10 wt.% during the reaction. R1, R3 = 1-4C alkyl; R2 = 4-30C aliphatic, cycloaliphatic or cycloaliphatic-aliphatic; a, b = optional additional bonds.

    Abstract: Preparation of propene and optionally 1-butene comprises converting butene isomers to propene isomers using metathesis catalyst and converting formed 2-pentene to propene and 1-butene, isolating and recycling the 2-butene fraction. Preparation of propene and optionally 1-butene comprises: (a) converting 1-butene and 2-butene in the presence of a metathesis catalyst containing group VIb, VIIb or VIII metals; (b) removing propene and 2-pentene formed; (c) converting the 2-pentene using ethene to propene and 1-butene in the presence of the metathesis catalyst in (a); (d) removing propene and 1-butene formed; and (e) discharging the 1-butene and partially isomerizing 1-butene to 2-butene in the presence of a catalyst and recycling the 1-butene and 2-butene with a part of the unreacted 4C-fraction from (a) to (a). An Independent claim is also included for the apparatus for carrying out the preparation of propene and 1-butene comprising a metathesis reactor (R01) connected to a distillation column (K101) for removing 2/3C low boiling, 4C middle boiling and 5C+ high boiling phases; column (K301) for removing ethene and propene; and reactor (R02) for reacting 2-pentene with ethene.

    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.
