Phosphorus-sulfur compounds have flame retardant activity in organic polymer systems. The phosphorus-sulfur compounds can be represented by the structure:
wherein X is oxygen or sulfur, T is a covalent bond, oxygen, sulfur or nitrogen, provided that at least one of X and T is sulfur, each X′ is independently oxygen or sulfur, each m is independently zero or 1 when X′ is oxygen and zero, 1 or 2 when X′ is sulfur, n is at least 1 and preferably at least 2, each R is independently an unsubstituted or inertly substituted hydrocarbyl group or the R groups together form an unsubstituted or inertly substituted divalent organic group and A is an organic linking group.

In a process for hydrogenating at least one organic compound, the organic compound or compounds is/are brought into contact with a hydrogen-containing gas in the presence of a catalyst which comprises, as active metal, ruthenium either alone or together with at least one further metal of transition group I, VII or VIII of the Periodic Table applied to a support material based on amorphons silicon dioxide and is obtainable by:
i) a single or multiple treatment of a support material based on amorphous silicon dioxide with a halogen-free aqueous solution of a low molecular weight ruthenium compound and subsequent drying of the treated support material at below 200° C.,
ii) reduction of the solid obtained in i) by means of hydrogen at from 100 to 350° C.,
with step ii) being carried out directly after step i).
