Method for producing unsymmetrical diphenylamines. |
摘要 |
<p>There is disclosed a process for the production of unsymmetrical, substituted diarylamines by the reaction of a primary aromatic amine and a substituted phenol wherein the phenol is held in excess of the primary aromatic amine thereby minimizing by-product formation as a result of self-condensation of the primary arylamine. The desired secondary amine is produced in high yield and purity by recycling the unreated phenol.</p> |
