This highly reactive chemical can be used in a wide variety of industrial proc- esses. Despite its marked reactivity, it can he handled without difficulty and its reactions can be readily controlled. Sodium can also be converted into con- centrated (40-60%) dispersions in inert media. These dispersions can be handled in pipes as fluids at room temperature. They allow rapid but controlled sodium reactions. Industrial Uses and Applications DYESTUFFS. S y n t h e t i c indigo, certain selenium colors, and many dye inter- mediates require sodium in their manu- facture. Naphthalene used by the dye- stuffs industry is refined with sodium. PHARMACEUTICALS. Barbituric acid de- rivatives, such as Luminal, Veronal, and many other soporifics of similar type, are made with sodium. Sodium is also used to refine many organic liquids used bv the pharmaceutical industry. MISCELLANEOUS CHEMICALS. D e t e r g e n t s , wetting agents, piasticizers, resins and insecticides may be manufactured with sodium. The perfume industry uses sodi- um for synthesizing odori ferous materials and for refining organic liquids. PREPARATION OF SODIUM DERIVATIVES. Sodium hydride, sodamide, sodium al- koxides and sodium acetylide are made from sodium. PREPARATION OF SODIUM ALLOYS. Al- loys of sodium with mercury, lead, tin, zinc, cadmium and other non-ferrous metals can be easily prepared. In the chemical industry some of these alloys are used as convenient forms in which to feed specific amounts of sodium to a reaction. Pulverized sodium-lead is re- acted with ethyl chloride in the manu- facture of lead tetraethyl. The alloys are also used in metallurgy. METALLURGY. Sodium is used for the re- moval of antimony and arsenic from lead-tin alloys; it forms compounds with many other non- ferrous metals and may, in certain cases, be used as a refining re- agent to remove these metals as impuri- ties and to deoxidize metals. Sodium treated steel has greatly improved impact strength at sub-zero temperatures. The wetting power and fluidity of molten metals is increased by small additions of sodium—effects which are important in applying hot-clip coatings and in pro- ducing sound castings. Fused caustic soda baths containing small percentages of sodium hydride, formed in place by sodium and hydrogen additions, have remarkable reducing properties. One commercial application of caustic soda-sodium hydride baths includes descaling and desanding ferrous and non-ferrous alloys in producing and fabricating mills.
