The present invention relates to a process for the production of carboxylic esters by reaction of carboxylic acids and/or carboxylic anhydrides with at least one alcohol selected from alkanols having at least 5 carbon atoms, cycloalkanols, and alkoxy-alkanols, in the presence of an acidic esterification catalyst. The invention further relates to the use of the resultant carboxylic esters as plasticizers or in a plasticizer composition for thermoplastic polymers and elastomers.

The combination of supportedrhodium metal catalysts and supercritical carbon dioxide solvent was effective for the stereoselective ring hydrogenations of aromatic compounds at low temperature. Higher solubility of hydrogen in supercritical carbon dioxide provides higher concentration of hydrogen on the rhodiumsurface, but lower that of the intermediate on rhodiumsurface, which suppresses the flipping

The invention relates to tetrahydrofuran derivatives of general formula (I), wherein X stands for *—(C═O)—O—, *—(CH2)n-O—, or *—(CH2)n-O—(C═O)—, wherein * represents the point of bonding to the tetrahydrofuran ring and n has the value 0, 1, or 2; and R1 and R2 are selected independently of each other from among C4-C5 alkyl and C5-C6 cycloalkyl, wherein the cycloalkyl groups are unsubstituted or can be substituted by at least one C1-C10 alkyl group, a plasticizer composition that contains said tetrahydrofuran derivatives, molding masses that contain a thermoplastic polymer or an elastomer and such a tetrahydrofuran derivative. The invention further relates to a method for producing said tetrahydrofuran derivatives, and to the use of said tetrahydrofuran derivatives
