Sulfur [7704-34-9] S, a nonmetallic element, is the second element of Group 16 (VIA) of the Periodic Table, coming below oxygen and above selenium. In massive elemental form, sulfur is often referred to as brimstone. Sulfur is one of the most important taw materials of the chemical industry. It is of prime importance to the fertilizer industry (see Fertilizers) and its consumption is generally regarded as one of the best measures of a nation s industrial development and economic activity (see Sulfur compounds Sulfurremoval and recovery Sulfuric acid and sulfur trioxide). [Pg.115]

A group at Industrial Research Limited in New Zealand recently reported the results of a study to determine if a cross-linked enzyme crystal-catalyzed resolution can compete with alternative chiral technologies in the pharmaceutical and chemical process industries. The group used the enantioselective hydrolysis of a-phenylethyl acetate catalyzed by ChiroCLEC -PC as a model system (Fig. 13). Based on their results with 270 kg of racemate, they evaluated the economics of mnning the process at the 600-kg batch scale and concluded that this process is economically feasible [38],... [Pg.222]

He represents the Singapore Chemical Industry in the ASEAN Ministerial Groupings meetings (AME1CC), the Asia-Pacific Economic Cooperation (APEC) Chemical Dialogues (APEC CD) and UNEP meetings. [Pg.145]

Additional chapters in the grouping broadly referred to as infrastructure include the new Recent History of the Chemical Industry 1973 to the Millennium and an update of the chapter titled Economic Aspects of the Chemical Industry, in which some of the material extends information provided in the former. Rounding out the infrastructure group are yet another new chapter Nanotechnology Principles and Applications, together with the earlier ones which cover such diverse and fundamental topics as process safety, emergency preparedness, and applied statistical methods. [Pg.1967]

Stoichiometric and catalytic transition-metal oxidation reactions are of great interest, because of their important role in industrial and synthetic processes. The oxidation of alkenes is one of the fundamental reactions in chemistry.1 Most bulk organic products contain functional groups, which are produced in the chemical industry by direct oxidation of the hydrocarbon feedstock. Usually these reactions employ catalysts to improve the yields, to reduce the necessary activation energy and render the reaction more economic. The synthesis of almost every product in chemical industry nowadays employs at least one catalytic step. The oxidation products of alkenes, epoxides and glycols, may be transformed into a variety of functional groups and therefore the selective and catalytic oxidation of alkenes is an industrially important process. [Pg.131]

The Organisation for Economic Co-Operation and Development s (OECD) categorization, demonstrating how diverse the industry is, divides the chemical industry into four groupings (OECD, 2001) ... [Pg.9]

The Bureau of Transport Economics and Statistics of the Interstate Commerce Commission is responsible for the freight statistics on commodities which can be used in various ways by the chemical industry. Since 1947, the bureau has had data, on a sample basis, of terminated traffic by commodity breakdowns. Issued quarterly, the Group V statistics titled Manufactures and Miscellaneous include numerous chemicals and chemical products. Number of carloads and tons are reported for Class I steam railways in the United States. Although no longer published, the state statistics by origination, destination, and commodity were useful data. Collection and publication of these figures were discontinued in January 1952. [Pg.6]

The Office of Business Economics, Department of Commerce, obtains dollar sales figures each month from representative chemical companies as well as data on inventories. The individual company figures are classified into three groups industrial chemicals, drugs and soaps, and other— which includes paints and fats and oils. From this information, it is possible to estimate total sales each month by the entire chemical industry. These estimates are published regularly in the Survey of Current Business a monthly service of the Department of Commerce. Manufacturers are thus able to compare their individual sales performance with the industry as a whole. Similarly, inventories are reported. Unfilled orders data are somewhat difficult to obtain for the chemical industry, however. [Pg.7]

Supported catalysts represent the largest group of heterogeneous catalysts and are of major economic importance, especially in refinery technology and the chemical industry. Supported catalysts are heterogeneous catalysts in which small amounts of catalytically active materials, especially metals, are applied to the surface of porous, mostly inert solids - the so-called supports. The supports can have special forms such as pellets, rings, extrudates, and granules. [Pg.180]
