    Abstract: PROBLEM TO BE SOLVED: To simplify reattachment of an existing partition wall column and assembly of a new partition wall column by detachably fitting a partition wall to the inside of the partition wall column. SOLUTION: Partition walls 3 are detachably fitted to the inside of a partition wall column. In other words, the partition walls 3 are fitted on one side of the respective packed beds 4 as a sheet of 0.1-3mm desirably about 1-2mm thickness and formed into a structural member integrated with the packed beds 4. In this case, the integrated partition wall 3 is formed longer than the packed bed 4 combined therewith in the edges of the head and the bottom by about 1-10mm and has an additional sheet strips 5 in the edge of the bottom. The sheet strip 5 has about 10-20mm width and about 0.1-2mm thickness. In the case of combining an individual packed bed 4, a roof type overlapped part is formed and thereby liquid is inhibited from infiltrating. The overlapped part is sealed sufficiently and strongly for infiltration of vapor.

    Abstract: PROBLEM TO BE SOLVED: To provide an improved method that enables to carry out, addition reaction between a Grignard compound and a carbonyl compound and the subsequent hydrolysis, without any trouble with respect to the plant-operation. SOLUTION: This method removes almost all the heat that is generated during exothermic reaction(s) of (a) an addition reaction between a halogenated organomagnesium compound shown by the formula RMgX (R is a 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl, or an aryl; X is Cl, Br, or I) and a carbonyl compound and/or (b) a hydrolysis of the resulting addition product, by carrying out at least one of these reactions in a solvent or a mixture of solvents and evaporating the solvent or the mixture of solvents.

    Abstract: Prodn. of 1,2,2-trimethyl- cyclopentylmethylketone derivs. of formula (I) comprises (A) (i) reacting a 2,2,6-tri- methyl-cyclohexane-1-one of formula (II) with a methylcarbanion of formula CH3 M (III) and converting the resulting 1,4-dihydroxy-1,2,2,6-tetramethylcyclohexane deriv. of formula (IV) into a mixt. of the corresp. cpds. (V) and (VI) by acid catalysed elimination of the tert. hydroxyl gp., or (A) (ii) the 2,2,6-trimethylcyclohexane-1-one cpd. (II) may be converted directly into the cpd. (VI) by a Wittig reaction with a triphenylmethylenephosphorane cpd. of formula (C6H5)3P=CH2 (VII); (B) converting the cpd. (VI) into the cpd. (V) by acid catalysed isomerisation of the double bond; (C) epoxidising the double bond in the cpd. (V) in the known way by reacting with peroxyacids, their salts or hydroperoxides to form the 7-oxa-bicycloÄ4.1.0Üheptane cpd. of formula (VIII) and (D) converting the cpd. (VIII) into the 1,2,2-tri- methyl-cyclopentylmethylketone cpd. (I) by reaction with Lewis acids and opt. splitting off the protective gp. from the O atom. R=H, alkyl, aryl, arylmethyl, trialkylsilyl, triarylsilyl, alkylarylsilyl, alkyloxyalkyl, tetrahydropyranyl, arylmethyloxycarbonyl, alkanoyl or benzoyl residue; M =Li, MgCl, MgBr or MgI.

    Abstract: Process for the production of stable dry powders which are insoluble in hot water and which contain fat-soluble vitamins and/or carotenoids, which comprises the following process steps: a) preparation of an aqueous dispersion containing essentially these fat-soluble active substances, film-forming colloids and reducing sugars, b)conversion of this dispersion into dry powders of vitamin and/or carotenoid products and c) thermal hardening of the powder at temperatures of 60 to 180 DEG C, and which is characterised in that gelatin in combination with one or more organic amino compounds which are free or bound as salts and which contain a basic primary amino group and additionally either another amino group, a hydroxyl group, an alkoxy group or a carboxyl group, and/or in combination with sufficient basic alkali metal or alkaline earth metal compound for the dispersion to have a pH of 7.5 to 10, is used as film-forming colloid, and the dry powders obtainable by this process are described.
