The carbonaceous residue of the destructive distillation (carbonization) of bituminous coal, pe- troleum, and coal-tar pitch. The principal type is that produced by heating bituminous coal in chem- ical recovery or beehive coke ovens (metaliurgical coke), one ton of coal vielding about 0.7 ton of coke. ft is used chiefly for reduction of iron ore in blast furnaces, and as a source of synthesis gas. Petroleum yields coke during the cracking process. Coke de- rived from petroleum residues and coal-tar pitch is used for refractory furnace finings in the electro- refining of aluminum and other high-temperature service, also for electrodes if electrolytic reduction of alumina to aluminum, as well as in electrothermal production of phosphorus, silicon carbide, and cal- cium carbide. cola (kola; kola nuts; kola seeds; Soudan coffee; guru).

The permanent deformation of a material that occurs as a result of prolanged compression or extension at or near room temperature. Some plas- tics and vulcanized rubber exhibit this behavior; in metals it is known as creep. cold rubber, Synthetic rubber produced by polymer- ization at relatively Jow temperatures; specifically, SBR or butadiene-styrene- elastomers produced by o molurherizatinn af ahaut comnared with usual polymerization at about 40°F compared with usual temperature of about 120°F. A special catalyst sys- tem is required. colemanite. The ore of calcium borate (Ca.B,0,,- 5H20). Sp. gr. 2.26-2.48. Used to replace boric acid in the manufacture of glass fibers. Mined in Turkey, it began to be imported into the U.S. in large volume in 1965 and is cornpetiive with domestically pro- duced B,O,, derived from kernite. “Colex."! Trademack for a finely powdered bone glue used for adhesion in water paints. cotistin CasHasNisQis. Antibiatic produced by a soil “microorganism. Probably identical to polymyazin E and closcly related chemically to polymyain B, since it is @ polypeptide composed of amino acids and a fatty acid. See polymyxin. collagen. A fibrous protein comprising most of the white fiber in the connective tissues of animals and man, especially in the skin, muscles and tendons. The most abundant protein in the animal kingdom, it is rich in proline and hydroxyproline. The molecule is analogous to a three-strand rope, in which each strand is a polypeptide chain; it has a molecular weight of about 100,000. Glue made from the collagen of anima] hides and skins is still widely used as an adhesive. So-called “soluble” collagen is that first formed in the skin; upon aging it becomes increas- ingly crosslinked and less hygroscopie. “Soluble” collagen is being used in the cosmetic industry as the basis for face creams, lotions and hair-dressing preparations. Special forms of collagen have been developed for dialysis membranes. Microcrystalline collagen is being used in prosthetic devices and other medical and surgical applications. Regenerated col- lagen, used in sausage casings, is made by neutraliz- ing with acid collagen that has been purified by alkaline treatment. Collagen is converted ta ‘gelatin by boiling in water, which causes hydrolytic cleavage of the protein to a mixture of degradation products. See aiso gelatin. . 2,4,6-colidine (2,4,6-trimethylpyndine} (CH))sCs HN. Properties: Colorless liquid. B.p. 170.4°C; freezing oint —44.5°C: sp. gr. 0.913 (20/20°C), refractive index (n 20/D)} 1.4981.
