The changes, however, are both numerous and significant. First of all, there is a change in the organization of the subject matter. For example, material formerly contained in the section entitled Analytical Chemistry is now grouped by operational categories spectroscopy electrolytes, electromotive force, and chemical equilibrium and practical laboratory information. Polymers, rubbers, fats, oils, and waxes constitute a large independent section.

Uses Organic synthesis (vitamins and drugs) analytical chemistry (cyanide analysis) solvent for anhydrous mineral salts denaturant for alcohol antifreeze mixtures textile dyeing waterproofing fungicides rubber chemicals. 

Zinc oxide occurs in nature as mineral zincite. It is the most important zinc compound and has numerous industrial applications. Zinc oxide is the pigment in white paints. It is used to make enamels, white printing inks, white glue, opaque glasses, rubber products and floor tiles. It is used in cosmetics, soaps, pharmaceuticals, dental cements, storage batteries, electrical equipment, and piezoelectric devices. Other applications are as a flame retardant, as a UV absorber in plastics, and a reagent in analytical chemistry. A major application of zinc oxide is in the preparation of most zinc salts. In medicine, the compound is used as an antiseptic, an astringent and a topical protectant.

The development in 1940 of the first commercial ultraviolet-risible spectrometer, the Beckman DU, and its marketing in 1941 (see chapter 4) revolutionized analytical chemistry and had significant impact on biology. During the early years of World War II another laboratory workhouse, the infrared spectrometer was developed in order to help solve a strategic national problem rubber.
