*Fast relief οί ïniesiinaî disorders with adsorpt ive At tapulgus Clays High potency, fast action, low-dosage requirement a r e built in Wyeth Laboratories* Polymagma" antidiarrheal preparations withM &C pharmaceutical-grade Attapulgus Clays (Pharmasorb*). With adsorbency five times that of previously-used materials, the Pharmasorb quickly adsorbs the diarrhea-causing factors in the intestines, distress stops, and recovery is fast.

Enormous surface area makes IVI & C At tapulgus CL*y products highly-sorptive toward liquids, gases, and odors . . . fits them for jobs where high surface activity will solve problems . . . check this starred item on the coupon to learn more.

UDEX* e x t r a c t i o n + p u r i f i c a t i o n by A t t a p u l g u s C l a y = u l t r a - p u r i t y a r o m a t i c s The Udex process, originated by Dow Chemical Company and developed and licensed by Uni­versal OU Products Company, uses glycol sol­vents in a liquid-phase extraction of high-purity aromatics from catalytic reformates, coke oven light oils, and other aromatic-rich hydrocarbon mixtures. Flexibility and economy of operation establish Udex popularity. Extreme puri ty a ro­matics a r e produced by liquid phase static bed percolation of the aromatics extract through Attapulgus Clay to remove traces of unsatura tes and other impurities which would limit t h e purity of the final products .

Because of basic reaction, low affinity for aromatics, and ability t o polymerize unsatu­rates, M & C's At tapulgus Clays are versatile adsorbents for purifying most hydrocarbon stocks. Contaminat ing trace elements remov­able from paraffin, cycloparaffin, aromatic hy­drocarbons b y these adsorbents a re non-cyclic unsaturates, arsenic and nitrogen compounds, strong acid esters, acidic and basic compounds, resins, polymers, and selective solvents.
