Abstract: A process for preparing phenoxyethanamines from phenols and 2-oxazolines in quantitative yields was discovered. Phosphoric acid hydrolyzes the amide intermediate from the phenol/2-oxazoline reaction without cleaving the amide at the ether linkage and without undesired aromatic ring substitution. Thus, yield to the desired phenoxyethanamines is often 98% or better, requiring no subsequent purification. In contrast, sulfuric and hydrochloric acids give these undesired side reactions. Phenoxyethanamines are useful in thermosetting resins, pharmaceuticals and as surfactants.

Abstract: An epoxy resin composition comprises the cured reaction product of an epoxy resin and a lactone-imidazole complex. For example, complexes of butyrolactone and caprolactone with 1-isopropyl-2-methyl imidazole were formed wherein the mole ratio of lactone:imidazole ranged from 1:1 to 2:1. The complexes are less reactive than the imidazole alone, giving them an extended pot life. The compositions are useful for making filament windings where an extended working time is required. Other applications include those in which it would be impractical to use the more reactive unmodified imidazole as the sole curing agent.
