Selected cyclohexane-1,3- and -1,4-dicarboxylic acid esters are described, as is their use as plasticizers in plastics and their preparation by hydrogenation of the corresponding isophthalic or terephthalic esters by bringing one or more of these isophthalic or terephthalic esters into contact with a hydrogen-containing gas in the presence of a catalyst which comprises, as active metal, at least one metal of the 8th transition group of the Periodic Table on its own or together with at least one metal of the 1st or 7th transition group of the Periodic Table, applied to a support, which comprises using a support having micropores.

Selected cyclohexane -1,3-and -1,4-dicarboxylic acid esters

A process for producing plasticizers in which a phthalic acid having the CAS Nos. 111381-89-6, 111381-90-9, 111381-91-0, 68515-44-6, 68515-45-7 and 3648-20-7, the formed plasticizers and a method of increasing the plasticity of a plastic product.

Hydrogenation of benzenepolycarboxylic acids or derivatives thereof using a catalyst containing macropores

Method for producing monoisocyanates and oligoisocyanates

Mixture of diesters of adipic or phthalic acid with isomers of nonanols

Method for hydrogenating benzene polycarboxylic acids or derivatives thereof by using a catalyst containing macropores

Monoacetals of aromatic 1,2-diketones are manufactured by reacting the corresponding 1,2-diketones, in an organic solvent, with an acid ester (R.sup.1).sub.n X as alkylating agent and an alcoholate (R.sup.2 O).sub.m Me, where R.sup.1 and R.sup.2 are identical or different hydrocarbon radicals of 1 to 12 carbon atoms, which may or may not be substituted, n and m are integers from 1 to 3, X is a monobasic, dibasic or tribasic acid radical and Me is a metal of main groups 1 to 3 of the periodic table of the elements. The resulting diketone monoacetals are particularly suitable for use as photoinitiators in photopolymerizable compositions.
