French scientists at the Pasteur Institute, however, promptly dispelled some of Prontosil s mystery, splitting the molecule into a red dye component and an old chemical, sulfanilamide, its 1909 patent long since lapsed (2 ). The suspicion arose that Domagk, an I. G. Farbenindustrie researcher, had rediscovered sulfanilamide, and that the manufacturer had held it off the market until it could be presented in a new, complex, disguised, and patentable form (2, 3 ) Whether or not the suspicion was true, the French scientists, by showing that sulfanilamide was the therapeutically active fraction of Prontosil, shattered the gigantic Germany company s profitable plans.

Ma.nufa.cture. AU. manufacturers of butynediol use formaldehyde ethynylation processes. The earliest entrant was BASF, which, as successor to I. G. Farben, continued operations at Ludwigshafen, FRG, after World War II. Later BASF also set up a U.S. plant at Geismar, La. The first company to manufacture in the United States was GAF in 1956 at Calvert City, Ky., and later at Texas City, Tex., and Seadrift, Tex. The most recent U.S. manufacturer is Du Pont, which went on stream at La Porte, Tex., about 1969. Joint ventures of GAF and Hbls in Mad, Germany, and of Du Pont and Idemitsu in Chiba, Japan, are the newest producers. 

Historically, the development of the acrylates proceeded slowly they first received serious attention from Otto Rohm. AcryUc acid (propenoic acid) was first prepared by the air oxidation of acrolein in 1843 (1,2). Methyl and ethyl acrylate were prepared in 1873, but were not observed to polymerize at that time (3). In 1880 poly(methyl acrylate) was reported by G. W. A. Kahlbaum, who noted that on dry distillation up to 320°C the polymer did not depolymerize (4). Rohm observed the remarkable properties of acryUc polymers while preparing for his doctoral dissertation in 1901 however, a quarter of a century elapsed before he was able to translate his observations into commercial reaUty. He obtained a U.S. patent on the sulfur vulcanization of acrylates in 1912 (5). Based on the continuing work in Rohm s laboratory, the first limited production of acrylates began in 1927 by the Rohm and Haas Company in Darmstadt, Germany (6). Use of this class of compounds has grown from that time to a total U.S. consumption in 1989 of approximately 400,000 metric tons. Total worldwide consumption is probably twice that.

The Ziegler process, based on reactions discovered in the 1950s, produces predorninandy linear, primary alcohols having an even number of carbon atoms. The process was commercialized by Continental Oil Company in the United States in 1962, by Condea Petrochemie in West Germany (a joint venture of Continental Oil Company and Deutsche Erdid, A.G.) in 1964, by Ethyl Corporation in the United States in 1965, and by the USSR in 1983. 

The 0X0 or hydroformylation reaction was discovered in Germany in 1938 (10) and was first used on a commercial scale by the Enjay Chemical Company (now Exxon) in 1948. By 1990 the total world alcohol capacity based on this general technology was over four million metric tons per year (see Oxo... 

The world s largest producers are Perstorp AB (Sweden, United States, Italy), Hoechst Celanese Corporation (United States, Canada), Degussa (Germany), and Hercules (United States) with estimated 1989 plant capacities of 65,000, 59,000, 30,000, and 22,000 t/yr, respectively. Worldwide capacity for pentaerythritol production was 316,000 t in 1989, about half of which was from the big four companies. Most of the remainder was produced in Asia (Japan, China, India, Korea, and Taiwan), Europe (Italy, Spain), or South America (Brazil, Chile). The estimated rate of production for 1989 was about 253,000 t or about 80% of nameplate capacity. 

The acquisition of the rights to the viscose process became one of the most profitable investments of aU time. Interest in the new fiber was intense, and growth of production capacity was exponential. By 1907, the Courtauld company was selling aU the artificial sHk it could produce and proceeded to expand into the U.S. market. In 1910 they formed the American Viscose Co. and in 1911 started the first U.S. viscose factory at Marcus Hook. By 1939, Courtaulds had six factories in the United States, seven in the United Kingdom, one in Erance, one in Canada, and joint ventures in Germany and Italy. 

Erom 1920 to 1931, after the expiration of the viscose patents, world output increased from 14,000 to 225,000 t per year, as more than 100 companies entered the ceUulose fiber field. In Europe, Vereinigte Glanstoff Eabriken (VGE, Germany), Enka (HoUand), I. G. Earben (Germany), Snia Viscosa (Italy), Comptoir des Textiles Artificiels (CTA, Erance), Rhodiaceta (Erance), Tubize (Belgium), and ChatiUon (Italy) were among the new starters. 

Fine chemicals are produced by a wide spectmm of manufacturers, largely because the distinction between different kinds of chemicals is not sharp. There are specialty producers of fine chemicals. Many companies that manufacture dmgs also manufacture the chemical substances that are used in preparing the dosage forms. A number of companies manufacture dmg chemicals and food chemicals. Some fine chemicals are made by manufacturers of heavy chemicals, and either may be simply a segment of their regular production, or some of that production which has been subjected to additional purification steps. Many fine chemicals are imported into the United States from countries such as Japan, Germany, and the Netherlands.

In Western Europe, the CPC producers are equally varied. The following is a partial Hst of the larger companies with total CPC production capacity (10 t) at all sites shown in parentheses Atochem SA (148.5, Prance and Spain), Hoescht AG (102.0, Germany), KaH-Chemie AG (66.0, Germany and Spain), Montefluos SpA (100.0, Italy), and ICI Chemicals and Polymers Ltd. (>113.6, United Kingdom). These producers account for over 80% of the Western European CPC production. 

Until 1982, almost all methyl methacrylate produced woddwide was derived from the acetone cyanohydrin (C-3) process. In 1982, Nippon Shokubai Kagaku Kogyo Company introduced an isobutylene-based (C-4) process, which was quickly followed by Mitsubishi Rayon Company in 1983 (66). Japan Methacryhc Monomer Company, a joint venture of Nippon Shokubai and Sumitomo Chemical Company, introduced a C-4-based plant in 1984 (67). Isobutylene processes are less economically attractive in the United States where isobutylene finds use in the synthesis of methyl /i / butyl ether, a pollution-reducing gasoline additive. BASF began operation of an ethylene-based (C-2) plant in Ludwigshafen, Germany, in 1990, but favorable economics appear to be limited to conditions unique to that site. 

Other companies with early involvement in developing nonwovens as textile replacements include Avondale Mills, Kimberly-Clark, The Kendall Company, and the West Point Manufacturing Company. Freudenburg of Germany, a worldwide producer of nonwoven interlinings (another woven fabric replacement), began efforts in the 1930s to find a substitute for leather (qv) (7). 

The large candles used by the U.S. Navy have been produced ia the United States by three companies. Mine Safety AppHances Company, Puritan-Beimett Corporation, and Scott Aviation. These sell for 50— 60. Production is less than 10,000/yr. Smaller candles incorporated ia breathing apparatus are produced by equipment suppHers. Production quantities are tied to the number of complete units and the candles are a small percentage of the total price. Production for aircraft oxygen supply during a decompression incident is about 50,000 units per year. In the United States, Puritan-Beimett and Scott Aviation are the primary suppHers as is Draeger in Germany. 

Naphthalene (qv) from coal tar continued to be the feedstock of choice ia both the United States and Germany until the late 1950s, when a shortage of naphthalene coupled with the availabihty of xylenes from a burgeoning petrochemical industry forced many companies to use o-xylene [95-47-6] (8). Air oxidation of 90% pure o-xylene to phthaUc anhydride was commercialized ia 1946 (9,10). An advantage of o-xylene is the theoretical yield to phthaUc anhydride of 1.395 kg/kg. With naphthalene, two of the ten carbon atoms are lost to carbon oxide formation and at most a 1.157-kg/kg yield is possible. Although both are suitable feedstocks, o-xylene is overwhelmingly favored. Coal-tar naphthalene is used ia some cases, eg, where it is readily available from coke operations ia steel mills (see Steel). Naphthalene can be produced by hydrodealkylation of substituted naphthalenes from refinery operations (8), but no refinery-produced napthalene is used as feedstock. Alkyl naphthalenes can be converted directiy to phthaUc anhydride, but at low yields (11,12).
