Red Phosphorus. This aHotropic form of phosphoms is relatively nontoxic and, unlike white phosphoms, is not spontaneously flammable. Red phosphoms is, however, easily ignited. It is a polymeric form of phosphoms having thermal stabiUty up to ca 450°C. In finely divided form it has been found to be a powerful flame-retardant additive (26,45—47). In Europe, it has found commercial use ia molded nylon electrical parts ia a coated and stabilized form. Handling hazards and color have deterred broad usage. The development of a series of masterbatches by Albright Wilson should facihtate further use. 

Bis(2-Chloroethyl) 2-Chloroethylphosphonate. The commercial product, Albright Wilson s Antiblaze 78, is a mixture having various related higher boiling diphosphonates. This product is made by the Arbuzov rearrangement of tris(2-chloroethyl) phosphite [140-08-9] ...

Albright Wilson s Vircol 82 is a diol mixture obtained by the reaction of propylene oxide and dibutyl acid pyrophosphate (112). The neutral Hquid has an OH number of 205 mg KOH/g and contains 11.3% phosphoms corresponding to the formula shown where x y = 3.4. The product is a mixture of isomers. 

Tetrakis(hydroxymethyl)phosphonium Salts. The reaction of formaldehyde (qv) and phosphine in aqueous hydrochloric or sulfuric acid yields tetrakis-(hydroxymethyl)phosphonium chloride [124-62-1/, Albright Wilson s Retardol C, or the sulfate [55566-30-8] (Retardol S), (C4H 2C4P)2SO [55566-30-8]. 

These are water-soluble crystalline compounds sold as concentrated aqueous solutions. The methylol groups are highly reactive (118—122) and capable of being cured on the fabric by reaction with ammonia or amino compounds to form durable cross-linked finishes, probably having phosphine oxide stmctures after post-oxidizing. This finishing process, as developed by Albright Wilson, is known as the Proban process. 

This provides a durable finish which, unlike many other flame retardants, can withstand repeated (50—100) launderiags without a loss of efficiency. An added advantage is that the feel of the cloth (hand) is Htde effected. Principal markets are ia the treatment of iadustrial protective clothing, military uniforms, and, ia Europe, for furnishings. These products are available from Albright Wilson Ltd. and Cytec Industries Inc. 

Beginning in approximately 1975, both IMG and Ereeport Minerals operated large uranium recovery plants in the United States using this technology. Several plants continue to mn but a number have been closed because of the depressed uranium prices that resulted when uranium from the former Soviet Union flooded Western markets. A relatively small plant is operated by Prayon in Belgium (40). TOPO is available from Cytec Industries Inc. as CYANEX 921 extractant. D2EHPA is available from Albright Wilson Ltd. and is also sold by Daihachi as DP-8R. 

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).

An explosion and fire at an Albright Wilson Americas phosphorus chemicals plant in Charleston, SC (June 17, 1991) killed six and injured 33. The damaged unit lost part of its walls and roof Eight other units on the 200 employee site, sustained minor or no damage, but were shutdown for a few days. At the time of the accident, plant workers were mixing chemicals in the No. 2 reactor in the special products unit when an explosion and fire occurred. Five of the people killed were contract employees not directly involved with the reactor, but were installing insulation nearby.
