Chemicals in Processing

T O D A Y a compound of tin is doing a remarkable job as an anti-wormant in veterinary medicine. A few years ago D r . Salsbury's Laboratories, pioneers in poultry pharmaceuticals, were looking for a chemical that would be non-toxic for poultry, but effective against the deadly poultry tapeworm, Raillietina cesticillixs. F o r experimental purposes hundreds of compounds of tin were s u p ­ plied b y Metal & Thermit. M & Τ Dibutyltin Dilaurate is now c o n ­ tained in two patented formulations of D r . Salsbury's " W o r m a l / * one of the most effective poultry tapewormers ever developed.

The array of metal parts, from screws and bolts to bumpers and frames, which g o into an assembled automobile repre­ sent yet another large market for chemi­ cals. Each part must b e chemically cleaned and degreased at least once during production; many are plated or have their surface protected and finished by other chemical means. For instance, last year's estimates put t h e amount of materials needed for preparing passenger cars JEor painting at 300,000 pounds of cleaner, 7 . 5 mil­ lion pounds of zinc phosphating chemi­ cals, and 120,000 pounds of chromic acid, as well as 2 million, pounds of water wash paint booth compound and 2 . 4 million pounds of alkali paint re­ mover. Plated surfaces average about 6 0 square feet per car for anodized alumi­ num and stainless steel, about 1 9 square feet for zinc and cadmium plated areas. For bumpers alone plating requires in t h e neighborhood of 4 million pounds of cleaner, 12.8 million of sulfuric acid, and 0.8 million pounds of sodium cya­ nide i n precleaning. J u s t to remove the sand from each automatic trans­ mission casting requires one p o u n d of caustic soda.
