General Description 2,6-Dimethylnaphthalene (2,6-DMN) is a key intermediate in the production of poly(ethylene naphthalate) (PEN) and can be selectively synthesized through catalytic methylation of naphthalene or its derivatives. It exhibits high selectivity in shape-selective reactions, particularly when using modified molecular sieves such as SAPO-11 or composite core-shell structures (e.g., Hβ/SAPO-11 or ZSM-5/SAPO-11), which optimize pore size and acid site distribution for improved yield. Efficient synthetic routes, such as a two-step process from 4-bromotoluene and 3-methyl-3-buten-1-ol, can achieve high yields (66%) without forming undesired isomers. Hierarchical or acid-modified catalysts further enhance performance by introducing mesopores and tuning acidity.
