Résumé : |
This work focuses on the synthesis of di amino diphenyl methane (DDM) using heterogeneous zeolite catalyst and evaluating its suitability in the wire enamel resins. The study consists of optimization of reaction conditions for making DDM isomer mixture containing at least 75 % of 4,4'-DDM isomer. Out of the three catalysts studied (H ZSM 5, H Beta and CBV 720), CBV 720 was found to perform well. CBV 720 was furthermodified with boric acid, phosphoric acid and tetra ethyl ortho silicate to prepare new catalysts with comparable efficacy. The DDM mixture made with boron modified CBV 720 was found suitable for preparing a polyester imide wire enamel resin. |
