    摘要: Hindered hydroxybenzylcyclopentadienes and derivatives thereof, useful as antioxidants, are prepared by reacting cyclopentadiene, an alkali metal, and a hindered p-methylphenol having a displaceable group attached to the methyl group in the presence of a non-protic solvent; or in one step, by reacting cyclopentadiene, hindered phenol that is devoid of a group in the para position, formaldehyde, an amine, water, and an alkali metal hydroxide in the presence of a phase transfer catalyst; or in one step, by reacting cyclopentadiene and a hindered substituted p-methyl-phenol containing a displaceable group, in the presence of a non-protic solvent, water, an alkali metal hydroxide and a phase transfer catalyst. These compounds readily dimerize whereas the bis compounds are prepared in presence of an excess amount of the substituted p-methylphenol.

    摘要: Disclosed herein are tricyclic and pentacyclic polyamines having a secondary or tertiary amine group on an amine functional substituent and at least one primary amine group on each of two amine functional substituents in the molecule. These compounds function excellently as non-visably carbonating epoxy curing agents and in addition unlike most other amines exhibit a mild amine odor.
