Many primary fatty amides which are available from various manufacturers are Hsted in Table 3. In 1986 approximately 55,000 metric tons of amides and bisamides were produced world wide (58), the majority of which are bisamides, followed in volume by primary amides. Most of these products are shipped in sohd form in bag or dmm quantities. Major producers of primary fatty amides are Akzo, Glyco, Humko, and Sherex. Bisamides are produced by Akzo, Milacron, and Syntex. There are over 100 producers of alkanolamides in the world, most of which are small specialized manufacturers to a specific industry. GAP, Henkel, Sherex, and Witco are among the principal producers. The most widely used alkanolamides are the Ai,Ai-bis(2-hydroxyethyl) fatty amides, mostly produced from middle-cut coco fatty acids (6% capryflc, 7% capric, 51% lauric, 19% myristic, 9% palmitic, and 2% stearic acids). An estimated 77,000 metric tons of alkanolamide was produced worldwide in 1986 (59).

The synthesis of triethoxysilane (28) and trimethoxysilane (29) has also been achieved by direct process. In 1980 there were no direct processes for the production of alkoxysilanes. In 1995 Silbond in Weston, Michigan, and Carboline in St. Louis, Missouri, operated processes for the production of tetraethoxysilane in the United States, and OSi/Witco announced start-up of a process to produce triethoxysilane and tetraethoxysilane in TermoH, Italy. 

Shell is the sole principal U.S. manufacturer of petroleum sulfonate having an estimated aimual plant capacity of ca 27,000 metric tons Witco and Peimrico-Morco are beheved to supply a total of ca 7,000 metric tons aimuaHy. 

Economic Aspects. Ammonium thiocyanate capacity in the United States is well in excess of 9000 t/yr on a 100% soHds basis, but production in the 1990s is substantially less than this capacity. In the United States only Witco produces ammonium thiocyanate. Production growth is small. The price of ammonium thiocyanate in mid-1995 was 2.02/kg.

Lanolin alcohols are obtained by saponification of purified wool grease, a mixture of high molecular esters that is recovered in wool (qv) scouring. Ethoxylation of purified lanolin alcohols yields a full series of lipophilic and hydrophilic nonionic emulsifiers whose largest use is in cosmetic preparations. Manufacturers include Amerchol, Croda, ICI, Henkel Corporation, Westbrook Lanolin, Witco, and Pulcra, SA.

Manufacturing plants for thioglycolic acid and derivatives are found in Europe, the United States, and Asia. Producers in Europe are B. Bock (Germany), Elf Atochem (Erance), and Merck (Germany) in the United States Elf Atochem, Hampshire, and Witco and in Japan, Daicel. Production capacity is expected to be sufficient to supply world demand for five years. 

Commercially available tin compounds having aimual production or gross sales of >2.3 metric tons or 5,000.00 are Hsted in References 194 and 195. Principal U.S. producers of inorganic tin compounds include M T Chemicals, Inc., Vulcan Materials Company, and Allied Corporation. M T Chemicals, Inc., is the largest U.S. producer of organotin compounds, followed by Carstab Corporation, Witco Chemical Corporation, and Cardinal Chemical Company minor producers are Interstab, Synthetic Products Company, Tenneco Chemicals Company, and Ferro Chemical Company...

The shrinkage in demand has resulted in a restmcturing of the carbon black-industry. Several of the principal multinational oil companies have left the business including Ashland, Cities Service Co., Phillips, and Conoco. Some plants have changed ownership. In the United States this has increased the production capacities of Degussa, Sid Richardson, and Huber. Today s U.S. industry consists of six principal producers. Rated capacities of the six U.S. manufacturers is shown in Table 13. Cabot Corp. and Columbian Chemicals are the leading producers, followed by Degussa, Sid Richardson, J. M. Huber Corp., and Witco. A survey of the future markets and present stmcture of the carbon black industry has been presented (1).
