    Abstract: 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

    Abstract: The present invention relates to a process for purifying benzenepolycarboxylic esters and for preparing cyclohexanepolycarboxylic esters by hydrogenating the purified benzenepolycarboxylic esters. The invention further relates to benzenepolycarboxylic esters and cyclohexanepolycarboxylic esters having a small proportion of by-products, especially of dialkyl ethers, and especially to diisononyl cyclohexane-1,2-dicarboxylate having a small proportion of diisononyl ether. The invention also relates to the use of the cyclohexanepolycarboxylic esters as plasticizers, especially in products intended for human contact, such as children's toys, food packaging and medical articles.

    Abstract: A process for preparing C4 to C10 monohydroxy compounds from a bottom fraction arising in the distillation of a crude mixture of C4 to C10 oxo-process aldehydes from cobalt-catalyzed or rhodium-catalyzed hydroformylation, or in the distillation of a crude mixture of C4 to C10 oxo-process alcohols, which comprises contacting the bottom fraction in the presence of hydrogen with a catalyst comprising copper oxide and aluminum oxide, at a temperature of 150° C. to 300° C. and a pressure of 20 bar to 300 bar and subjecting the resulting crude hydrogenation product to distillation, and the amount of C4 to C10 monohydroxy compounds present in the crude hydrogenation product after the hydrogenation being greater than the amount of C4 to C10 monohydroxy compounds given stoichiometrically from the hydrogenation of the ester and aldehyde compounds present in the bottom fraction, including the C4 to C10 monohydroxy compounds still present in the bottom fraction before the hydrogenation.
