Abstract: Alkanols, alkylamines or hydroxylamines are reacted with a cycloalkene oxide in the presence of Fuller's earth as a catalyst to prepare, respectively, 2-cycloalkanol ethers, 2-alkylamino-cycloalkanols, or 2-hydroxylamino-cycloalkanols.

Abstract: It has been found that a sulphur containing resin which is the condensation product of (i) one or more mercaptoaldehydes and (ii) one or more meta-substituted phenols has good antioxidant properties. Mixtures of m/p-alkylphenols are used to particular advantage in the production of this resin. A small amount of the resin retards the oxidation of rubbers or polyolefins and the resin is particularly useful as a melt stabilizer during the extrusion of a polymer.

Abstract: A condensation product of a mercaptoaldehyde, e.g. butylmercaptopropionaldehyde, and phenol or a phenol having a substituent ortho or para to the hydroxyl group and being unsubstituted in a position ortho or para to the hydroxyl group, e.g. o-cresol, has free radical inhibiting and hydroperoxide decomposing properties. The condensate also has metal deactivating properties when the phenol has a halogen in an ortho or para position. The condensate which may be a bisphenol or a liquid or solid resinous material, is particularly useful as an antioxidant in liquid hydrocarbons.
