A method is provided for fabricating a diol containing a bis-cycloaliphate. The diol is hydrogenated with hydrogen and a catalyst. Therein, the diol has a bis-aromatic. The catalyst comprises an active metal and a catalyst carrier. The active metal is a VIII-B-group transition element. The catalyst carrier is an oxide of IV-B-group element. Thus, the diol containing the bis-cycloaliphate is generated.

Method of fabricating diol containing bis-cycloaliphate

The present invention discloses a process for making alicyclic polycarboxylic acids or their derivatives, referring to a process for hydrogenating aromatic polycarboxylic acids or their derivatives in the presence of hydrogen and a catalyst to form alicyclic polycarboxylic acids or their derivatives, and the catalyst comprises at least one active metal of group VIIIB transition elements of the periodic table of elements, and a catalyst support comprising group IIA and group IIIA elements in a specific weight ratio.

Process for making alicyclic polycarboxylic acids or their derivatives

This invention discloses the process for hydrogenation of aromatic polycarboxylic acids or derivatives thereof, hydrogenation of aromatic polycarboxylic acids or derivatives thereof can be achieved in the present of the catalyst, which consist at least one metal of the eighth transition group of the Periodic Table as the active metal while group IIA and group IVA elements are included as the catalyst support.

Process for hydrogenation of aromatic polycarboxylic acids or derivatives thereof to the corresponding alicyclic polycarboxylic acids or derivatives thereof
