摘要： 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.

摘要： A method for producing secondary amines, particularly fatty secondary amines such as ditallowamine from fatty nitriles, such as tallow nitrile over a reduction, hydrogenation catalyst, such as nickel or cobalt, in two steps has been discovered. The reaction gives high selectivity of secondary amine over the coproduced primary and tertiary amines. The first step of the reaction is conducted continuously in the presence of ammonia and hydrogen. The secondary amine proportion is increased by a second stage using the same catalyst as the first stage, but in the absence of ammonia.
