MONO-tert-BUTYL-meta-CRESOL
Koppers Mono-6-tertiary-butyl-meta-cresol is a clear, liquid, alkylated tar acid which melts at a temperature slightly below room temperature. In this disubstituted phenol, two of the three normally reactive nuclear positions are unsubstituted and are subject to reactions such as acylation, sulfurization, nitration, alkylation, and condensation with aldehydes. This compound is a powerful germicide for the formulation of disinfectants. It is used in the production of perfume fixatives such as musk ambrette, for rubber and petroleum chemicals, modified phenolic resins, and fine chemicals. The compound is described in detail in Bulletin C-9-130. Bulletin C-9-130-1 describes the preparation of some typical Mono-tert-butylmeta-cresol disinfectants.
PHTHALIC ANHYDRIDE Koppers Phthalic Anhydride is a flaked, white solid with a minimum freezing point of 130.7°C. This highly-refined compound possesses excellent color stability and is free of colorproducing impurities. Phthalic Anhydride is used in large quantities for the production of alkyd resins, ester-type plasticizers, dye intermediates, insect repellents, pharmaceuticals, and miscellaneous organic chemicals such as tetrachlorophthalic anhydride, phthalide, and phthalonitrile. o C-B-CM^CHj

H NONYL PHENOL
Koppers Nonyl Phenol is a clear yellow liquid possessing a slight phenolic odor. This compound undergoes the reactions typical of mono-alkylated phenols. Nonyl Phenol is useful for the production of synthetic detergents and other surface-active agents, for the preparation of lubricating-oil additives, and oil soluble resins. It is also of interest as an intermediate for the production of plasticizers, agricultural chemicals, antioxidants, pharmaceuticals, and corrosion inhibitors. Detailed discussion of the compound is given in Bulletin No. C-9-125.
PENACOLiTE® ADHESIVES Penacolite® Adhesives are resorcinol-aldehyde resin products developed for the bonding of wood and other cellulosic materials, laminated phenolics, plastics, and rubber goods. These resin adhesives are unusual because they cure at room temperature without the use of strong-acid catalysts, and form good bonds at low pressures. The neutral, cured bond is infusible, fungus-resistant, waterproof, boilproof, and weatherproof. These adhesives are available in a number of forms and grades to meet various requirements. Special bulletins are available describing their uses and methods of application.
PHENOLSULFONIC ACID SO,H
Koppers Phenolsulfonic Acid is available as an aqueous solution assaying 65-68% sulfonic acid, in which the para-isomer predominates. This compound undergoes many of the reactions typical of a phenol and a sulfonic acid such as alkylation, aldehyde condensations, acylation, and esterification. The material is suggested for use in the production of synthetic ionexchange resins, as an electrolyte additive for the electrodeposition of metals, as a catalyst, and as a chemical intermediate.
Koppers Propiophenone (phenyl ethyl ketone) is a clear liquid possessing a strong, pleasant odor. Its chemical reactions are typical of an aromatic ketone and are similar to those of acetophenone. This material finds application in the production of pharmaceuticals and dyestuffs, and as a perfume fixative. The product is discussed in detail in Bulletin No. C-9-133. COOH
beta-RESORCYUC ACID Koppers beta-Resorcylic Acid (2,4-dihydroxybenzoic acid) is a white, crystalline, high-melting solid which is slightly soluble in water. This compound, combining many of the chemical properties of resorcinol and benzoic acid, is used in the production of specialty dyestuffs and as an intermediate for the preparation of fine chemicals.

RESORCINOL
Koppers Resorcinol (meta-dihydroxybenzene) is a watersoluble, crystalline, dihydric phenol. This highly reactive compound undergoes most of the typical reactions of phenols including nitration, alkylation, condensation with aldehydes, etherification, and oxidation. It is widely used for the preparation of low-pressure, room-temperature setting resorcinolformaldehyde resin-adhesives. The compound is also used to modify phenol-formaldehyde, urea-formaldehyde, caseinformaldehyde, and analogous resins. It finds application as a chemical intermediate for dyestuffs, medicinals, textile and leather chemicals, explosives, and compasitions giving increased adhesion of rubber to fabric. The chemistry and uses of Resorcinol are covered in Bulletin No. C-9-124.

SODIUM SULFIH
Koppers technical Sodium Sulfite is available as a free-flowing, light-brown anhydrous, water-soluble salt. In aqueous solutions it acts as a reducing agent and yields sulfur dioxide when acidified. It is used as an oxygen-removal agent in treating boiler-feed water, as an antichlor in textile manufacture, as a bleaching agent, in the semi-chemical pulping of wood, and as a chemical intermediate. This grade is not suitable for photographic purposes.

POLYSTYRENE STYRENE MONOMER Koppers Styrene Monomer is a clear, colorless, liquid, aromatic hydrocarbon available in tank-car quantities with a purity of at least 99.3 %. This reactive compound polymerizes with itself to form polystyrene molding products, and with other active olefinic compounds to produce synthetic rubbers, polyester laminating and casting resins, ion-exchange resins, and specialty synthetic elastomers. Its copolymers with drying oils and with a Ik yd resins are finding increasing use in protective coatings. Styrene Monomer is also a versatile chemical raw material, yielding organic intermediates useful for further chemical synthesis. Bulletin C-8-119 gives the properties of Koppers Styrene Monomer. Bulletin C-9-119-1 describes storage conditions for Styrene Monomer.
Koppers Polystyrene is an outstanding thermoplastic molding material which merits the consideration of all molders of thermoplastic products. Polystyrene is the lightest of the modern rigid plastics, and is the least expensive of the thermoplastics. It is outstanding for its ease of molding and for its adaptability to various fabricating techniques. Koppers Polystyrene, produced by Koppers from its own Styrene Monomer, is held within rigid product specifications. It is available as a crystalclear, colorless plastic, in black and white, and in a wide range of transparent, translucent, and opaque colors. The high quality of this material, its excellent heat resistance and dimensional stability, and its low specific gravity favor the large-scale use of this thermoplastic. Bulletin C-9-137 describes Koppers Polystyrenes in detail.
