What is proposed is a continuous process for producing limonene which has the feature that beta-pinene or beta-pinene-containing starting materials are isomerized in a trickle-bed reactor in the presence of acid catalysts.

Process for preparing limonene and composition containing limonene

A process is proposed for preparing unsaturated macrocyclic monoketones, comprising the following steps:

Method for preparing unsaturated macrocyclic ketones (II)

The invention relates to a method for producing terpene aldehydes and terpene ketones by oxidatively dehydrogenating the corresponding terpene alcohols, comprising or consisting of the following steps: (a) providing terpene alcohols or terpene-alcohol-containing reactants; (b) bringing the starting substances from step (a) in contact with a heterogeneous ruthenium catalyst; (c) heating the mixture from step (b) to at least 150&#xb0; C. in the presence of oxygen; optionally (d) separating the terpene aldehydes or terpene ketones from the obtained reaction mixture.

Method for producing terpene aldehydes and terpene ketones

A method for producing unsaturated macrocyclic monoketones comprising the following steps: (a) preparing macrocyclic dienes with a ring size of at least 9 carbon atoms; (b) contacting the starting materials from step (a) with (b1) a palladium(II) salt and/or a palladium(II) complex; and (b2) an oxidant; and (b3) a solvent; and optionally (b4) a ligand; and optionally (b5) a co-catalyst; and optionally (b6) an acid.

Method for synthesising an unsaturated macrocyclic ketone

The invention relates to a process for producing 17-oxabicyclo[14.1.0]heptadec-8-ene comprising a reaction with the reactants cyclohexadeca-1,9-diene and hydrogen peroxide.

Process for the production of 17-oxabicyclo[14.1.0]heptadec-8-ene

A process for the preparation of 1,2-pentanediol by reaction of a starting material comprising one or both compounds from the group consisting of furfuryl alcohol and furfural with hydrogen in the presence of a first heterogeneous catalyst is described.

Method for producing 1,2-pentanediol

The invention relates to a method for the production of an aromatic carbonyl compound by the oxidation of a methyl group or methylene group bonded to the aromatic group in which the aromatic substance is reacted in the presence of an oxidizing agent and a sulphoxide, a sulphoxide being selected for the oxidation of a specific aromatic substance whose ionization potential, in terms of magnitude, differs from the ionization potential of the aromatic substance to be oxidized by a maximum of &#xb1;0.25 eV.

Method for the production of aromatic carbonyl compounds

The present invention relates to a process for preparing aldehydes or ketones using an alkali metal hypochlorite or an alkaline earth metal hypochlorite in the presence of a ruthenium catalysts.

Process for the ruthenium-catalysed oxidation of alcohols by means of hypochlorite
