Chemicals from Propylene and Butylene, used by petroleum refineries internally to alkylate gasolines. This captive use is not reported. Of the propylene used for chemical manufacture, nearly 40% is polymerized to polypropylene, to be discussed in a later chapter. Of the remaining amount of propylene, seven chemicals from the top 50 are

The Second Fifty Industrial Chemicals, on a large scale, and an understanding and appreciation of these chemicals, their manufacture and uses, provides the student with a solid background in industrial chemicals. We might ask ourselves what comes next? What are some other important large-scale chemicals that, though not made quite at th

Basic Polymer Chemistry: Thermoplastics,ur discussions of this subject, which will be quite detailed. The polymer industry stands out above all others as a consumer of heavy organic chemicals. The U.S. polymer industry produces over 100 billion lb of polymers and 50% of industrial chemists work with polymers. Thus we can see the importanc

Fibers,. Probably the first synthetic fiber experiment came with the work of Christian Sch?nbein, who made cellulose trinitrate in 1846. After breaking a flask of nitric and sulfuric acids, he wiped up the mess with a cotton apron and hung it in front of the stove to dry. Cellulose trinitrate was developed

Elastomers, the first to describe the rubber balls used by Indians. Natural rubber was brought back to Europe from the Amazon in 1735 by Charles Condamine, a French mathematical geographer, but it remained only a curiosity. Michael Faraday made a rubber hose from it in 1824. But it was not until Charles Goodye

Coatings and Adhesives,esives. These are quite large areas of the chemical industry. The size of the coatings industry is best estimated by NAICS 325510, Paints and Coatings, which had 1998 U.S. shipments of $18.7 billion. The increase in this segment is graphed in Fig. 19.1 along with the three main subdivisions of the i
