Epoxidized C -C cyclohydrocarbon compounds, for example, epoxidized C -C cycloalkanes, cycloalkenes and/or cycloalkadienes are converted to cycloalkanols, cycloalkanones and cycloalkanes by hydrogenating the epoxidized C -C cyclohydrocarbon compounds with hydrogen under a pressure of 0.1 to 5.4 MPa at a temperature of 100 to 280&deg; C. in the presence of a catalyst containing at least one platinum group metal, for example, Pd or Ru.

Method of hydrogenating epoxidized C6&mdash;C12 cyclohydrocarbon compounds

A dehydration catalyst useful for producing a monoalkylether of dihydric phenolic compound by a dehydration reaction of a dihydric phenolic compound with a lower alkyl alcohol with a high conversion at a high selectivity, comprises at least one inorganic substance of the empirical formula (I):
