Process for producing norbornene derivative having organosilyl group

A process for making cycloalkyldimethanol, includes hydrogenating at least one cycloalkyldicarboxylic acid and/or an alkyl ester thereof with a catalyst, to produce a cycloalkyldimethanol, where the catalyst contains ruthenium, tin and platinum. Also, a method for regenerating a used catalyst, includes contacting the used catalyst with a base, where the catalyst includes ruthenium, tin and platinum.

Process for the manufacture of cycloalkyldimethanol

An epoxy compound formula (1), and a hydrogenation process for preparing thereof;

Hydrogenated diglycidyl ethers of bipheny-4,4&prime;-diol

Disclosed is a process for producing a compound having at least one epoxy group, which comprises: subjecting a compound having at least one carbon--carbon unsaturated bond and at least one epoxy group to selective hydrogenation in the presence of a catalyst comprising at least one of rhodium and ruthenium supported on a carbonaceous support, the carbonaceous support having a specific surface area of from 5 to 600 m.sup.2 /g, to thereby selectively hydrogenate the at least one carbon--carbon unsaturated bond.
