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.

Abstract: Metallaphotoredox catalysis merges the powerful bond-forming abilities of transition metal catalysis with unique electron or energy transfer pathways accessible in photoexcited states, injecting new vitality into organic synthesis. However, most transition metal catalysts cannot be excited by visible light. Thus, prevalent metallaphotoredox catalytic systems require dual catalysts: a transition metal catalyst and a separate photosensitizer. This leads to inefficient electron transfer between the[...]
