Lithium is presently being recovered from brines of Searles Lake, in California, and from those in Nevada. Large deposits of quadramene are found in North Carolina. The metal is produced electrolytically from the fused chloride. Lithium is silvery in appearance, much like Na and K, other members of the alkali metal series. It reacts with water, but not as vigorously as sodium. Lithium imparts a beautiful crimson color to a flame, but when the metal burns strongly, the flame is a dazzling white. 

Attributed to C. N. Reilley (1925-1981) on receipt of the 1965 Fisher Award in Analytical Chemistry. ReiUey, who was a professor of chemistry at the University of North Carolina at Chapel HiU, was one of the most influential analytical chemists of the last half of the twentieth century. 

Before beginning an academic career I was, of course, a student. My interest in chemistry and teaching was nurtured by many fine teachers at Westtown Friends School, Knox College, and the University of North Carolina at Chapel ITill their collective influence continues to bear fruit. In particular, I wish to recognize David Macinnes, Alan ITiebert, Robert Kooser, and Richard Linton. 

Pella r, Nia.cin Deficiency. It was 220 years after the first description of pellagra that nicotinic acid was discovered to be the cure for black tongue in dogs (14), a condition suggested by a veterinarian in North Carolina to be similar to human pellagra (15). 

Georgia, Idaho, North Carolina, and Oregon also have some reserves.

In 1990, North Carolina produced 60% of the total scrap mica the remainder was produced in Connecticut, Georgia, New Mexico, Pennsylvania, South Carolina, and South Dakota. In 1991, the five largest producers produced 67% of the nation s total output (Table 9) (15).

The Los Alamos water boiler served as a prototype for the first university training reactor, started in September 1953 at North Carolina State College. The cylindrical reactor core used uranyl sulfate [1314-64-3] UO2SO4, and cooling water tubes wound inside the stainless steel container. A thick graphite reflector surrounded the core. 

Launched ia 1959, N. A. Savannah operated very weU. Starting ia 1962, it made a goodwill voyage around the world. It was able to travel a distance of several times the earth s circumference on one fuel loading. However, the ship was not competitive economically with oil-powered merchant ships. The shielding was quite adequate, so that the reactor was safe. Nonetheless the vessel was opposed by antinuclear groups and the N.A. Savannah was eventually retired and put on display ia Charleston, South Carolina. In 1994, the ship was transferred to Norfolk, Virginia, to be held ia reserve. 

Pecans. Pecan is the most important horticultural crop native to North America (163). The United States is the only substantial producer of pecan, despite the fact that pecans have been introduced into AustraUa, Israel, South Africa, and Argentina. The principal producing states, from high to low, are Georgia, Texas, New Mexico, Louisiana, Alabama, Oklahoma, Mississippi, North Carolina, South Carolina, Florida, Arkansas, and California. Domestic production of 135,597 t/yr in 1990—1991 was valued at 308,954,500 (153). 

In a similar appHcation, Cape Industries has announced its intention to commission a solvent extraction plant to recover acetic acid from an effluent generated at its dimethyl terephthalate [120-61-6] faciHty (Wilmington, North Carolina) (44,45). The plant was commissioned in Eebmary 1995. In this case, the solvent will be CYANEX 923 extractant [100786-00-3], CYANEX 923 is also a phosphine oxide, but unlike TOPO is a Hquid and can be used without a diluent (46,47). This has the benefit of reducing plant size, capital, and operating costs. 

A second pressure on elemental production was the development of processes which remove impurities from phosphoric acid made by the wet process, to generate acid of equivalent purity to that obtained by the electric furnace route. Two such plants were brought on stream one at Aurora, North Carolina in 1990 by a joint venture of Albright Wilson, Texasgulf, and Olin, and another at Geismar, Louisiana, in 1991 by Rhc ne-Poulenc. These units have reported capacities of 47,600 and 31,700 t/yr elemental phosphoms equivalent, respectively (14).
