possesses little toxicity,high boiling point,poweful solvency,good
selectivity and stability properties.The product is widely applied
to aromatic hydrocarbons extracting,acetylene,and diolefine purification.It
can be also used as polymer solvents and pulymerization process
medium,such as polyamides,polyimides amd polyphenyl thioether(pps),etc.which
are called engineering plastics.Besides these,it can be used as
aromatic fibre,pesticide,insulate pigment and detergent,etc.
