Scope
This standard applies to 1,2,4,5-tetrachlorobenzene, which is made from heavy aromatic hydrocarbons of carbon 9 and carbon 10 obtained by the reforming of petroleum fractions or the production of aromatic hydrocarbons from methanol, and is produced through the processes of distillation, isomerization, and crystalline separation. This product is mainly used as a raw material for the production of phthalic anhydride.
