- Abstract
Syntheses of methylenedianilines over zeolites with various structures were studied. It was found out that the most selective catalyst for the synthesis of 4,4'-methylenedianiline isomer was zeolite Y. Further, the kinetic data showed that initial N,N'-diphenylmethylenediamine reacted over zeolite catalysts by even one order of magnitude faster that the intermediate product 4-amino-N benzylaniline. The most suitable temperature range for the synthesis of 4,4'-methylenedianiline isomer was further identified as a range of 100 to 120°C.
