Carboxjiates with a fiuorinated alkyl chain ate marketed by the 3M/Industrial Chemical Products Company under the trade name Fluotad surfactants. They also include other functional derivatives of fiuorinated and perfluorinated alkyl chains. Replacement of hydrogens on the hydrophobe by fluorine atoms leads to surfactant molecules of unusually low surface tension. This property imparts excellent leveling effectiveness. 

Worz et al. describe in detail why micro reactors can give advantages concerning all three tasks [110-112]. They illustrate their analysis by two application examples, concerning a liquid/liquid reaction and a catalyzed gas-phase reaction, both representing industrial chemical production processes.

The multi-functionality of metal oxides1,13 is one of the key aspects which allow realizing selectively on metal oxide catalysts complex multi-step transformations, such as w-butane or n-pentane selective oxidation.14,15 This multi-functionality of metal oxides is also the key aspect to implement a new sustainable industrial chemical production.16 The challenge to realize complex multi-step reactions over solid catalysts and ideally achieve 100% selectivity requires an understanding of the surface micro-kinetic and the relationship with the multi-functionality of the catalytic surface.17 However, the control of the catalyst multi-functionality requires the ability also to control their nano-architecture, e.g. the spatial arrangement of the active sites around the first centre of chemisorption of the incoming molecule.1... 

Chemical production is a further area of characteristics and specifics in the chemical industry. Chemical products are produced in production processes including a reaction of chemicals. These production processes can be differentiated in continuous, campaign and batch production processes as illustrated in fig. 29.

Polychlorodibenzofurans are extremely toxic trace atmospheric contaminants which can be detected and identified in manufactured polychlorophenols and thus may appear in a variety of industrial chemical products. They are toxic to mammals, causing chloracne and producing extensive irreversible liver damage (76JOC2428).

Besides their utilization in the production of many compounds with therapeutic, diagnostic, and immunizing applications, animal cell cultures have undoubted utility in the performance of in vitro cytotoxicity tests. They can be used for the evaluation of potential anti-neoplastic agents and assessment of the safety of various products, such as pharmaceuticals, cosmetics, alimentary additives, pesticides, and industrial chemical products. Cell culture systems are frequently employed in the cancer chemotherapy field, in which their potential value for viability and cytotoxicity tests is largely accepted. Animal models play an important role in toxicity testing, but the pressure to adopt in vitro tests is growing since they present considerable economical advantages over in vivo tests. The use of animal models is limited to human metabolism studies, and there are... 

It is not the intention of this chapter to give an extensive review of the subject headlined but instead to discuss fundamentals, ways to select key chemicals, and, finally, examples for the current status of industrial chemical production from biomass. 

Table 2.2.1 Examples of the current status of industrial chemical production from biomass.

Transition metal catalysts, specifically those composed of iron nanoparticles, are widely employed in industrial chemical production and pollution abatement applications [67], Iron also plays a cracial role in many important biological processes. Iron oxides are economical alternatives to more costly catalysts and show activity for the oxidation of methane [68], conversion of carbon monoxide to carbon dioxide [58], and the transformation of various hydrocarbons [69,70]. In addition, iron oxides have good catalytic lifetimes and are resistant to high concentrations of moisture and CO which often poison other catalysts [71]. Li et al. have observed that nanosized iron oxides are highly active for CO oxidation at low tanperatures [58]. Iron is unique and more active than other catalyst and support materials because it is easily reduced and provides a large number of potential active sites because of its highly disordered and defect rich structure [72, 73]. Previous gas-phase smdies of cationic iron clusters have included determination of the thermochemistry and bond energies of iron cluster oxides and iron carbonyl complexes by Armentrout and co-workers [74, 75], and a classification of the dissociation patterns of small iron oxide cluster cations by Schwarz et al. [76]. 

To further this discussion let us divide environmental chemicals into three broad groups. First there is the enormous group of naturally-occurring chemicals that reach us primarily through food, but also through other media. Second are industrial chemical products that are produced for specific purposes. And third are the industrial pollutants - chemical by-products of fuel use, the chemical industry, and most other types of manufacturing.

The limited attention to impact on the environment and human health given by companies (apart few of them) during the period of fast development of industrial chemical productions (approximately the 1960-1980s). 

However, global competiveness and market should be considered. This is the real barrier for a more sustainable industrial chemistry. Therefore, the real step forward could derive only when the product value of chemical compounds also includes components related to the process of production, its impact on environment and safety of operations. We live in a global world, not only economically but also environmentally, where the impact of industrial production and human activities is no longer on a local scale. The value of products should thus not be related only to the local cost of production, which hides part of the effective costs (for the environment, for example, or for society, when risk is too high). It is thus necessary to adopt transparent procedures where cost is not only determined from the market but also includes the production procedures. This concept of traceability of chemical products is one of the concepts around which the new REACH legislation was built. The next section discusses in more detail this legislation, because it is an important component for the sustainability of chemistry and industrial chemical production not only inside Europe. 

It will be thus necessary to introduce a hierarchical approach. Lapkin et al. [65] have proposed four vertical hierarchy levels (i) product and process, (ii) company, (iii) infrastructure and (iv) society. Each level should reflect different boundary limits and use an appropriate choice of indicators. It is proposed also that the choice of appropriate indicators depends on the speciflcs of the industry sector and even on the types of products. The indicators should reflect speciflc by-products, wastes and emissions that are characteristic of the process or the product. Of course, alimit of the approach is how to make uniform the comparison between diflferent industrial sectors. On the other hand, we have already remarked that industrial chemical production is different from other manufacture industrial sectors, because (i) it includes very different types of productions, from several thousand tons per day in refinery to kg amounts per day in fine chemical production and (ii) it is characterized by a highly integrated structure in which a large part of the products are the input for other chemical processes. 

The activity of exogenous chemical substances on the human organism can be observed under various circumstances eth-nopharmacology, popular medicines, clinical observation of secondary effects or adverse events, fortuitous observation of activities of industrial chemical products, etc. As in all cases, the harvested information is observed directly in man, this approach presents a notable advantage. 

Therefore, the concept of flash chemistry may lead to a paradigm shift in laboratory chemical studies and industrial chemical production. It is hoped that various types of flash chemistry based on different methods of activating molecules and generating reactive reagents or intermediates, which may undergo a variety of reactions, will be developed and widely utilized in chemical research and in chemical plants to meet the demands of rapid and selective synthesis of various organic small molecules and polymers in the future. 

I have provided your supervisors with copies of a document on MSDSs that should be very helpful as you proceed in this work. It is a section entitled Exploring MSDSs found in the book Building Student Safety Habits for the Workplace, published by Terrific Science Press at the Center for Chemical Education at Miami University, Middletown, OH. This section includes a set of instructions for doing exactly what is required for this project (Exercise 3B). I also have made photocopies of the labels in question (found in Section 2B in the above referenced book) and the MSDSs (found in Section 3B in the above referenced book). Also, your supervisors will decide who should evaluate which labels. I have recommended that each participant be assigned two of the four chemicals (four labels) at random, meaning that each participant will each have four labels to evaluate, a consumer product label and an industrial chemical product label for one chemical and a consumer product label and industrial chemical product label for a second chemical. Please use the method suggested for Exercise 3B in the book referenced above and keep a good record of your work in your notebook so that you can prepare a quality report memo for WSHA. 

Figure 2 shows the UV spectrum of an industrial chemical product used for the diagnosis of metallic surface defaults. In case of a small crack, for example, the default remains coloured in red. The UV-visible spectrum shows an important peak at 552 nm, probably due to the presence of an unknown azo-dye.
