It is widely acknowledged that there is a growing need for more environmentally acceptable processes in the chemical industry. This trend towards what has become known as ‘Green Chemistry’ or ‘Sustainable Technology’ necessitates a paradigm shift from traditional concepts of process efficiency Catalysis, one of the overarching principles of green chemistry, is capable of producing substantial material and energy savings as well as economic benefits. When comparing catalytic methods to traditional stoichiometric syntheses, catalysis offers undisputable economy in reagent use. Stoichiometric reactions would require at least one mole of reagent per mole of starting material, whereas a catalyst, subject to turnover number (TON), can carry out a transformation multiple times per mole of catalyst. Catalytic reagents can be used to improve product selectivity, by enabling diastereomeric control and site specific transformations in multi-functionalised molecules. Moreover catalysts allow reactions to precede under milder reaction conditions. Moreover, catalytic methods can circumvent the need for pre-functionalization of the starting materials with activating or directing groups, which would later need to be removed from the final molecule. Thus the use of catalytic rather than stoichiometric methods can dramatically enhance the atom economy of a synthesis, save time and energy, as well as decreasing the amount of raw materials consumed and waste generated. The development and application of catalytic methods can significantly improve both the economic and environmental profile when designing synthetic routes within process research and development.
Although corrosion is a common problem in mines, as are material failures, there has been limited documentation of these issues in the literature or at conferences. The few presentations written are scattered throughout various journals, and are not always identified with mining or corrosion. Some of the frequently encountered problems are presented here to generate a more open discussion of corrosion and metallurgy in coal mining. Of course, much of what is described also applies to hard-rock mining. Probably the most important factor in corrosion of steels in coal mines is the mine water; however, just as with other industrial waters, the composition and corrosivity of these waters are highly variable. Yet little has been done by the mining industry to develop a comprehensive understanding of mine water corrosion, let alone allow effective modeling of corrosion caused by water. Rawat1 concluded that corrosion in coal mines was attributable to high relative humidity (>90%), high temperature (~30 °C [86 °F]), and airborne dusts. Moreover, the cause of acidity of mine waters is explained by the decomposition and oxidation of pyrites, the presence of peaty acids, and certain bacteria (Thiobacillus thiooxydans and Thiobacillus ferrooxydans). Furthermore, the chloride and sulfate content in mine water is a good indicator of corrosivity. It is also important to note that oxygen is always present in these waters.
