    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: The invention relates to a method for producing adsorbates suitable for huma n or animal nutrition, or for cosmetic applications. According to said method, a component (A) that is to be adsorbed is applied to a supporting material (C) using at least one stabilising agent (B), whereby the average particle size of the supporting material (C) is at least 80 .mu.m, with the proviso that if t he component (A) to be adsorbed is vitamin E, the mixture of (A) and (B) has an HLB value of less than 7 and also with the proviso that if the component (A) to be adsorbed is a fat-soluble vitamin and the stabilising agent (B) is a glyceride, the solidification point of the mixture of (A) and (B) is less th an or equal to 80 ~C. The invention also relates to the use of the adsorbates obtained in such a manner.
