First:

Then

Now:

Next? After being the first company

in the U.S. to produce a fiber grade TA (and still the only company that can supply both Dimethyl Terephthalate and Terephthalic Acid to polyester fiber and film manufacturers)...

After developing and becoming the major source of IPA (Isophthalic Acid) for polyesters, allcyds and plasticizers. . . .

And after introducing TMA (Trimellitic Anhydride), a unique intermediate for vinyl plasticizers and water-based surface coatings (that has met with such wide acceptance we are building a 50 million-lb.-a-year plant). . . .

Amoco now invites your evaluation of the newest structure in its Aromatic Acids Development Program: PID A.

Chemically, AMOCO PIDA is 1,1,3-trimethyl-S-carboxy-3-(p-carboxyphenyl) indan.

It differs from any other commercially produced aromatic di-acid because of its non-planarity, asymmetric carbon and separation of the aromatic portions of the molecule by an alicyclic structure.

But after PIDA what? We'll keep you informed.

In the meantime, let us know your aromatic acids requirements.

Contact your Amoco representative. Or write on your letterhead to: Amoco Chemicals Corporation, Department 9861, 130 East Randolph Drive, Chicago, Illinois 60601.
