| titleOfInvention | Preparation of Methylenedianiline and Mixtures of Higher Homologs thereof Using Calcined Metal Oxide-Silica Catalyst |
| abstract | The present disclosure discloses amines (eg, methylenedianiline (MDA) with acid catalysts, including, for example, metal oxide-silica catalysts calcined at temperatures above about 500 ° C. to form solid acid silica-metal oxide catalysts. A composition, system, and method for the formation of)). The metal oxide of the solid acid silica-metal oxide catalyst may comprise alumina. The process for preparing the solid acid silica-metal oxide catalyst may include calcining the amorphous alumina-silica material at a temperature of about 500 ° C. or higher and / or under anhydrous and / or inert atmosphere. The rearrangement reaction of the condensation product of aniline with formaldehyde in the presence of a solid acid silica-metal oxide catalyst is more preferred of more MDA and / or MDA than the reaction carried out using the corresponding catalyst calcined at temperatures below 500 ° C. Isomer (s) can be generated. |
