Addition of (trimethylsilyl)acetylides to chiral a-aminoalkyl- (413) and a-alkoxyalkyl-(BIGN) (292) nitrones proceeds stereoselectively. Successive desi-lylation (BU4NF, THF) and transformation of the ethynyl group into carboxyl (RuCl3-NaIC>4) led to the synthesis of diastereomerically pure /V-hydroxy-a-amino acids (414) and a-amino acids (415) (Scheme 2.185) (199, 202, 652, 660).

Broaden the application to cover reactive hazards resulting from process-specific conditions and combinations of chemicals. Additionally, broaden coverage of hazards from self-reactive chemicals. In expanding PSM coverage, use objective criteria. Consider criteria such as the North American Industry Classification System (NAICS), a reactive hazard classification system (e.g., based on heat of reaction or toxic gas evolution), incident history, or catastrophic potential. 

A performance-based system-rather than a list of reactive chemicals -is suggested as another alternative for extending regulatory coverage of reactive hazards. Such a system would consider the risk of reactive chemicals, site-specific (extrinsic) factors such as siting and proximity, and conditions that create potentially reactive situations. Objective criteria such as the North American Industry Classification System (NAICS) codes, accident history, or number of employees could be used to establish coverage. 

A safety case approach along the lines of the Seveso63 requirements is another possible alternative for determining regulatory coverage. The safety case requires a detailed explanation of why a process is safe to operate. Again, objective criteria such as NAICS codes, thermodynamic properties, or some combination of those criteria previously discussed are used to establish coverage.

Referring back to Fig. 16.1, we see that the value of U.S. shipments for cellulosic and noncellulosic fibers, though quite small compared to plastics, is still a big industry. While Plastics Materials and Resins (NAICS 325211) in 1998 was 44.9 billion, Noncellulosic Fibers (NAICS 325222) was 10.5 billion and Cellulosic Fibers (NAICS 325221) was 1.5 billion. These two fibers together have a 12.0 billion value, which is 3% of Chemical Manufacturing. We must also remember that many of these fibers are sold outside the chemical industry, such as in Textile Mill Products, Apparel, and Furniture, all large segments of the economy. The importance of fibers is obvious. In 1920 U.S. per capita use was 30 Ib/yr, whereas in 1990 it was 66 Ib/yr. From 1920 to 1970 the most important fiber by far was cotton. 

Today both natural mbber, an agricultural crop, and synthetic elastomers are multi-billion dollar businesses. Looking back at Fig. 16.1, we see that Synthetic Rubber (NAICS 325212) totals 5.7 billion. It is a large area of polymer use and is 1% of Chemical Manufacturing. But in the related industry covering final end products called Plastics and Rubber Products... 

Manufacturing (NAICS 326), Rubber Products (NAICS 3262) totals 35.3 billion, of which Tires (NAICS 32621) makes up 15.4 billion, showing the dominance of the automobile tire market in this sector of the chemical industry. The top polymer production summary in Table 1.16 gives a numerical list of important synthetic elastomers. Styrene-butadiene rubber (SBR) dominates the list at 1.93 billion lb for U.S. production. All other synthetic elastomers are much smaller. While elastomers had a slight increase in production from 1980-1990, only 0.5% annually, SBR was down 2.3% per year. From 1990-2000 it was up 1.0% per year. The fastest growing elastomer is ethylene-propylene, up 5.2% annually for 1990-2000. Table 18.1 gives a breakdown in percent production of synthetic elastomers and consumption of natural rubber in the U.S. 

In Chemical Manufacturing there is a subsector entitled Gum and Wood Chemicals (NAICS 3251911) that covers many of the miscellaneous chemicals that we have discussed here, including charcoal, tall oil, rosin, turpentine, and pine oil. The value of shipments is 960 million. The pulp... 

The sugar chain of ARS2 was oxidized, partially cleaved with 30 mM NaIC>4 at 4°C in the dark, and reduced with NaBH4 at room temperature overnight. For controlled Smith degradation, the polyol derivatives of ARS2 were hydrolyzed with 100 mM H2SO4 at room temperature for 16 hr.

The electric power sector comprises electricity-only and combined-heat-and-power (CHP) plants within the NAICS 22 category whose primary business is to sell electricity, or electricity and heat, to the public.
