Abstract: The common aromatic polyamide composite reverse osmosis(RO) membrane is easy to be oxidated. N,N'-Dimethyl-1,3-benzenediamine(DMMPD)as a key functional monomer can be used to prepare the chlorine resistance RO membrane by interfacial polymerization technology.  In this work, the DMMPD was synthesized by reduction method with composite reductant NaBH4-I2. The m-phenylenediamine as substrate was first reacted with the acylating agent of formic acid to get the intermediate N,N'-diformyl-m-phenylenediamine, then the resulting intermediate was reduced by NaBH4-I2 to obtain the final product DMMPD, the synthetic technology was further optimized through orthogonal test, and the proposed mechanism of reduction was discussed. The chemical structures of all products were identified via infrared spectra(IR), hydrogen nuclear magnetic resonance(1H  NMR) and mass spectragraph(MS). This current method for preparing the DMMPD has several advantages, including accessible substrate, mild reaction condition, relatively low cost and high yield.
