Patent number: 5276192Abstract: 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.Type: GrantFiled: April 22, 1991Date of Patent: January 4, 1994Assignee: Texaco Chemical CompanyInventors: Wei-Yang Su, George P.
