PRODUCTION OF MIXTURES OF METHYLENEDIANILINE AND ITS HIGHER HOMOLOGUES USING CALCINED METAL OXIDE-SILICA CATALYSTS

The present disclosure relates to compositions, systems, and methods of forming an amine (e.g., methylenedianiline (MDA)) using an acid catalyst including, for example, a metal oxide-silica catalyst calcined at temperature(s) of about >=500° C. to form a solid acid silica-metal oxide catalyst.
