Phosphoms trichloride is also used in the manufacture of antifoam agents, catalysts, dyes and pigments, as well as pharmaceutical and quaternary compounds, and is commonly used as a chlorinating agent. Phosphoms trichloride is used to make phosphoms oxychloride, which is used in the manufacture of adsorbents for air filters, antifoam agents, dyes and pigments, mineral-processing materials, pharmaceuticals (qv), and solvents. These uses represented 32,000 t of PCl in 1988 and 30,000 t in 1994. 

Three West Virginia coals were supplied by the West Virgmia Geological Survey (WVGS). The particular coals were chosen on the basis of rank, petrographic composition, and mineral matter content The coals were limited to the bituminous rank since these coals are the most amenable to the NMP solvent extraction process and are mdigenous to the Appalachian region. Some of the coal characteristics are listed in Table 2.

Commonly used solvents inclnde liqnid carbon dioxide, propane, bntane, light oil, triethy-lamine, acetone, methanol, hexane, dimethyl ether, cmde oil, benzene, isopropyl ether, toluene, tricresyl phosphate, methyl isobutyl ketone, methyl chloride, and bntyl acetate. In addition to remediation uses, solvent extraction has been applied in a variety of indnstries, including food processing, pharmaceuticals, fine chemicals, and mining and minerals processing. 

The wood industry is the major consumer of technical chloro-phenols. In the United States and in Canada it has been assumed that more than Q0% of pentachlorophenol (PCP) is used for wood perservation and wood protection (38,5jJ. PCP dissolved in various solvents (mineral spirits, fuel oil, kerosene and methylene chloride), is the major compound used for wood perservation. This procedure involves the use of pressure and vacuum cycles to obtain deep and optimum retention of the perservative. This process is used to produce a product which will have a long period of service such as railway ties, pilings and hydropoles.

An anhydrous solvent extraction process for bitumen recovery has been attempted and usually involves the use of a low-boiling hydrocarbon. The process generally involves up to four steps. In the mixer step, fresh tar sand is mixed with recycle solvent that contains some bitumen and small amounts of water and mineral. Solvent-to-bitumen weight ratio is adjusted to approximately 0.5. The drain step consists of a three-stage countercurrent wash. Settling and draining time is approximately 30 min for each stage. 

Abstract Ionic liquids as green solvents have shown important application in extraction and separation of metals. In this chapter, the new application perspective and the important fundamental and applied studies of the extraction and separation of metals in ionic liquids which include metal oxide processing, mineral processing, electrodeposition of metals (especially reactive metals such as Al, Mg, and Ti), and extraction of metal ions are presented. 

Typical systems are unsaturated polyesters, usually filled with mineral fillers and/or fibres. Newer systems such as thermoset-thermoplastics using reactive solvents for processing high-performance engineering polymers are being researched.
