Thanks go to Dr. Michael McKee at Auburn University and the Alabama Research and Education Network, both of which allowed software to be tested on their computers. Thanks are also due the Nichols Research Corporation and Computer Sciences Corporation and particularly Scott von Laven and David Ivey for being so tolerant of employees engaged in such job-related extracurricular activities.

Most of the voltage savings in the air cathode electrolyzer results from the change in the cathode reaction and a reduction in the solution ohmic drop as a result of the absence of the hydrogen bubble gas void fraction in the catholyte. The air cathode electrolyzer operates at 2.1 V at 3 kA/m or approximately 1450 d-c kW-h per ton of NaOH. The air cathode technology has been demonstrated in commercial sized equipment at Occidental Chemical s Muscle Shoals, Alabama plant. However, it is not presentiy being practiced because the technology is too expensive to commercialize at power costs of 20 to 30 mils (1 mil = 0.1 /kW). 

Direct Application Rock. Finely ground phosphate rock has had limited use as a direct-appHcation fertilizer for many years. There have been widely varying results. Direct appHcation of phosphate rock worldwide amounts to about 8% of total fertilizer phosphate used, primarily in the former Soviet Union, France, Brazil, Sri Lanka, Malaysia, and Indonesia. The agronomic effectiveness of an apatitic rock depends not only on the fineness of the grind but also strongly on the innate reactivity of the rock and the acidity of the sod performance is better on more acid sods. Probably more than half of the potentially productive tropical sods are acidic, some with pH as low as 3.5—4.5. Certain phosphate rocks may thus become increasingly important as fertilizer in those areas. The International Fertilizer Development Center at Muscle Shoals, Alabama is active in researching this field (30). 

TuU Chemical Co. (Oxford, Alabama) is the only producer of sodium fluoroacetate. It is sometimes colored with the black dye nigrosine. It is usually packed in 8 oz (227 g) or 5 kg cans and is almost exclusively exported. There is very limited use in the United States. 

The unconventional reserves of natural gas occur principally in the form of recoverable methane from coal beds. As of 1991, reserves of coal bed methane totaled 8.6 EJ (8.2 x 10 Btu), principally in the states of Alabama, Colorado, and New Mexico (16). 

Two pilot plants have been built and operated to demonstrate the feasibiHty of the SRC process. These iacluded a 6 t/d plant at Wdsonvihe, Alabama (p de infra) and a 50 t/d plant at Ft. Lewis, Washington which was operated from 1974 to 1981. 

Coal Liquefaction at Wilsonville. Starting ia 1974 the Advanced Coal Liquefaction R D Facihty at WilsonviUe, Alabama operated a 6 t/d pilot plant and studied various coal Hquefaction processiag schemes. The facihty, cosponsored by the DOE, the Electric Power Research Institute (EPRI) and Amoco Oil Co, was shut down ia early 1992. 

In the multistep production of IPDI, isophorone is first converted to 3-cyano-3,5,5-trknethylcyclohexanone (231—235), then hydrogenated and ammoniated to 3-aminomethyl-3,5,5-trknethyl-l-aminocyclohexane (1) (236,237), also known as isophorone diamine (IPDA). In the final step IPDA is phosgenated to yield IPDI (2) (238). Commercial production of IPDI began in the United States in 1992 with the startup of Olin s 7000 t/yr plant at Lake Charles, Louisiana (239), and the startup of Hbls integrated isophorone derivatives plant in Theodore, Alabama (240). Hbls has a worldwide capacity for IPDA of 40,000 t/yr. 

North America.. In the United States, lignite deposits are located in the northern Great Plains and in the Gulf states. Subbituminous coal is found along the Rocky Mountains. The western half of North Dakota has about 74% of the nation s resources, Montana 23%, Texas 2%, and Alabama and South Dakota about 0.5% each. The lignite resources to 914 m represent 28% of the total toimage of all coal deposits in the United States. The lower cost and low sulfur content have contributed to rapid growth in production. 

There were 113 commercial and captive lime plants in the United States as of 1993. Of these plants, the 10 largest produce about 35% of total lime output. Ohio is the largest lime producing state, followed by Peimsylvania, Missouri, Kentucky, Alabama, Texas, Illinois, Indiana, Virginia, and Arizona. 

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).

High alumina clays refer ia the ceramic iadustries to nodular clays, budey-flint clay, budey and diaspore, gibbsitic or bauxitic kaolins (clays), abrasive clays, and others. Siace the depletion of diaspore varieties ia Missouri and Pennsylvania, most bauxitic kaolin and clay is produced ia Alabama and Arkansas. 

Sulfur-coated urea is produced ki North America by a number of suppHers including ICl Canada (Courtright, Ontario), Lesco, Inc. (Martins Ferry, Ohio), PurseU Industries (Sylacauga, Alabama), and The O.M. Scott Sons Co. (Marysville, Ohio). All produce a number of fertilizer grades and particle sizes. Sulfur-coated ureas and compound (N—P—K) fertilizers also are produced by Mitsui Toatsu (Japan).
