The committee discussed the issues pertaining to restoration the customs duty on the import of
Phthalic Anhydride and directed to Federal Board of Revenue (FBR) to consider the said matter with stakeholders, chemical associations and report in this regard may be submitted to the Committee within seven days.

Stepan Company is a major manufacturer of specialty chemicals including surfactants, antimicrobials, fabric softening quaternaries,
phthalic anhydride and polyurethane polyols, as well as specialty ingredients for the food and nutraceutical markets.
This shows that the precursor ions and dominant fragmented ions of phthalates in EI ionization were typically m/z 149, corresponding to the protonated
phthalic anhydride ion [[[C.sub.8][H.sub.5][O.sub.3]].sup.+] [37].
So, we planned to synthesize the N-aryl phthalimides from
phthalic acid and aryl amines and evaluate them biologically to find out the novel lead candidates.
Additionally, the solution of soluble solid was found to contain 2,6-NDA and
phthalic acid by LC-MS.
The major components for this resin are
phthalic anhydride and 2-propenal (acrolein).
