Highly efficient two-step selective synthesis of 2,6-dimethylnaphthalene

2,6-Dimethylnaphthalene (2,6-DMN), a key raw material for poly(ethylene naphthalate) (PEN), was selectively synthesized via a two-step process in an overall 66% yield from commercially available 4-bromotoluene and 3-methyl-3-buten-1-ol. The ligand-free Heck reaction of the starting materials produced γ-(p-tolyl)-substituted aldehyde that was cyclized with an acid to give 2,6-DMN after in situ oxidation. No other isomers of 2,6-DMN were found.

Controllable synthesis of chainlike hierarchical ZSM-5 templated by sucrose and its catalytic performance

Hierarchical ZSM-5 with controllable chainlike structure was hydrothermally synthesized with sucrose as template, characterized by XRD, FT-IR, N2 adsorption, SEM and TEM, and used for methylation of 2-methylnaphthalene. Hierarchical ZSM-5 can be rapidly synthesized, and chainlike morphology is stacked with several submicron crystals. With increasing sucrose amount in the precursor, the chain structure became more obvious, and the surface area and pore volume of mesopores increased. Narrow mesoporous distribution was centered at about 7 nm. It is thought that the formation of mesopores is related to the template role of sucrose. Chainlike hierarchical ZSM-5 exhibited high 2-methylnaphthalene conversion and 2,6-dimethylnaphthalene yield.

Method for preparing 2, 6-dimethylnaphthalene

The invention relates to a method for preparing a bicyclic aromatic chemical 2, 6-dimethylnaphthalene (2, 6-DMN) from isoprene and 3-cyclohexene formaldehyde. The method comprises the following steps:heating the isoprene and the 3-cyclohexene formaldehyde or heating the isoprene and the 3-cyclohexene formaldehyde under a Lewis acid heating condition to carry out Diels-Alder reaction at the temperature of 200-350 DEG C to generate an organic matter A with the structure shown in the specification, and carrying out dehydrogenation and hydrodeoxygenation reaction on the organic matter A at the temperature of 300-450 DEG C at the same time to generate the 2, 6-dimethylnaphthalene. The process is simple in reaction procedure and high in target product selectivity, and a new route for preparingthe bicyclic aromatic compound from biomass resources is provided.
