Miscellaneous chemicals

Miscellaneous chemicals are used to modify the final properties of rigid polyurethane foams. Eor example, halogenated materials are used for flammabihty reduction, diols may be added for toughness or flexibiUty, and terephthalate-based polyester polyols may be used for decreased flammabiUty and smoke generation. Measurements of flammabihty and smoke characteristics are made with laboratory tests and do not necessarily reflect the effects of foams in actual fire situations. 

Another significant butadiene use is for manufacturing adiponittile, NC(CH2)4CN [111-69-3] a precursor for nylon-6,6 production. It accounted for about 13% of total U.S. butadiene consumption in 1989. Other miscellaneous chemical uses, such as for ENB (ethyHdene norhornene) production, account...

Benzene and many of its derivatives are manufactured on a large scale for use in high-octane gasolines and in the production of polymers, insecticides, detergents, dyes, and many miscellaneous chemicals. Prior to World War II, coal was the only important source of aromatic hydrocarbons, but during the war and thereafter, the demand for benzene, methylbenzene, and the dimethyl-benzenes rose so sharply that other sources had to be found. Today, most of tbe benzene and almost all of the methylbenzene and the dimethylbenzenes produced in the United States are derived from petroleum.

Uhe stockpile (the subject of the Amy s Chemical Stockpile Disposal Program) consists of (1) bulk containers of nerve and blister agents and (2) munitions, including rockets, mines, bombs, projectiles, and spray tanks, loaded with nerve or blister agents. Buried chemical warfare materiel, recovered chemical warfare materiel, binary weapons (in which two nonlethal components are mixed after firing to yield a lethal nerve agent), former production facilities, and miscellaneous chemical warfare materiel are not included in the stockpile. The disposition of these five classes of materials is the subject of a separate Non-Stockpile Chemical Materiel Pro-... 

In a typical 80,000 tons/year plant, capital costs were about 220 per metric ton in 1974. To produce 1000 kg of polymer, 1030 kg of monomer is needed, together with 1 kg of hydrogen and 25 kg of diluent. Catalyst and miscellaneous chemicals cost about 4 per 1000 kg of polyethylene pellets produced. For production, 300 kg of medium-pressure steam, 800 kg of low-pressure steam, 530 kWh of electrical energy, 200 m3 of water, 30 m3 of nitrogen, and 600 m3 of air are also required. To polymerize propylene in suspension, the same technology can be used. Catalysts now available [based on TiCl3 (see Table II)] make it unnecessary to separate isotactic from atactic materials.
