Molecule Structure Image



1,4-Dimethylbenzene is an aromatic hydrocarbon, based on benzene with two methyl substituents. It is an isomer of xylene. It is used on a large scale for the manufacture of terephthalic acid for polyester. Its polymer is known as Parylene. 1,4-Dimethylbenzene is produced by catalytic reforming of naptha and separated in a series of distillation, adsorbtion or crystallization and reaction processes from m-xylene, o-xylene and ethylbenzene.
