Method for making methylene dianiline and polymethylene polyanilines using sapo-18 molecular sieve
Patent published on the 2026-06-18 in WO under Ref WO2026128799 by DOW GLOBAL TECH LLC [US] (Steelman David Keith [us], Barton David G [us], Wang Hongyi [us], Chojecki Adam [nl])
Abstract: Mixtures of methylene dianiline isomers and polymethylene polyanilines are made with controllable methylene dianiline isomer ratios. Aniline and formaldehyde are reacted to produce N,N -diphenylmethylene diamine (aminal), which is then partially rearranged to a mixture of aminobenzyl aniline isomers and methylene dianiline isomers in the presence of a SAPO-18 molecular sieve. Further rearrangement may be performed in the presence of a homogeneous catalyst to convert the remaining aminobenzyl ani[...]
Our summary: The method involves producing methylene dianiline and polymethylene polyanilines using a SAPO-18 molecular sieve. Methylene dianiline isomer ratios can be controlled through the reaction of aniline and formaldehyde. Further rearrangement with a homogeneous catalyst converts remaining isomers to the desired products.
