摘要: 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.
