<p>Polyepoxyalkyl ethers, esters and amines containing at least one cyclohexane or saturated heterocyclic ring are prepared by hydrogenation of polyepoxyalkyl ethers, esters and amines containing at least one aromatic or unsaturated heterocyclic ring at temperatures below 150 DEG C. in the presence of a catalyst which is Ru or Rh metal supported on a finely divided carrier which is carbon or alpha-alumina, the amount of Ru or Rh metal being 0.1 to 10% by weight of the epoxy compound. Some of the polyepoxy ethers so obtained are novel compounds. The starting materials may be epoxy resins containing benzene rings or polyepoxy compounds which can be cured to give resins. Numerous curing agents are specified. Examples III, IX, XII describe the hydrogenation of epoxy resins; Example XV relates to the hydrogenation of a copolymer of allyl glycidyl ether and styrene; Examples XXIII-XXVI describe the preparation of resins from hydrogenated epoxy monomers.ALSO:The invention comprises (A) ethers of the formula R-O-R1, wherein R is a radical containing a cyclohexane ring attached directly to the ether oxygen and containing no epoxy rings, and R1 is a C2- 12 acyclic vic-epoxy alkyl radical, (B) an epoxy ether of the formula <FORM:1094138/C2/1> where Y is a C2- 12 vic-epoxy alkyl radical, R1 is hydrogen or a hydrocarbon radical and X is a divalent radical, e.g. an ether or sulphone linkage, or an alkylene linkage which may be substituted, e.g. by ester groups, (C) a glycidyl ether of the formula <FORM:1094138/C2/2> where R is a divalent cyclohexyl radical and n is 1-10, (D) a polyglycidyl ether of a polyhydric alcohol of the formula <FORM:1094138/C2/3> where n is 0 or 1-25, and (E) a general process for preparing epoxyalkyl ethers, esters and amines containing a cyclohexane or a saturated heterocyclic ring, whereby an epoxyalkyl ether, ester or amine, containing at least one epoxy group and at least one aromatic or unsaturated heterocyclic ring, is reacted with hydrogen at a temperature below 150 DEG C. in the presence of a finely divided catalyst supported on an inert carrier which is non-reactive with epoxy groups, the catalyst containing Ru or Rh metal and the carrier being finely divided carbon or alpha-alumina, the amount of catalyst metal being 0.1-10% by wt. of epoxy compound. Numerous novel ethers and starting materials for the general process are specified. The polyepoxy compounds may be cured to give epoxy resins (see Division C3).</p> |
