Aldehydes are produced by unmodified rhodium catalyzed hydroformylation process in a homogeneous organic phase using a solution of unmodified rhodium catalyst and an organic acid in a total amount, calculated as acid equivalent, of from greater than 3 moles to 3000 moles of acid per mole of rhodium. The organic acid is selected from: saturated aliphatic monocarboxylic acids having from 5 to 13 carbon atoms in the molecule; saturated aliphatic dicarboxylic acids having from 5 to 13 carbon atoms in the molecule; sulphonic acids having from 1 to 12 carbon atoms in the molecule; and combinations thereof. Use of the process can lead to either a significant increase in conversion without reducing selectivity for the desired aldehyde or a reduction in the specific use of rhodium.

Method for the production of aldehydes

The present invention relates to a process for preparing 3(4),8(9)-dihydroxymethyltricyclo[5.2.10]decane by hydrogenating the hyd roformylation products of d icyclopentad lene. The process comprises carrying out the hydrogenation in the presence of water, optionally after addition of water.

Process for preparing TCD-alcohol DM

A process for purifying alicyclic alcohols by distillation, wherein the alicyclic alcohols are distilled in the presence of from 1 to 550 ppm of acidic compounds.
