Technology and chemistry

The technology and chemistry of isoalkane-alkene alkylation have been thoroughly reviewed for both liquid and solid acid catalysts (15) and for solid acid catalysts alone (16). The intention of this review is to provide an up-to-date overview of the alkylation reaction with both liquid and solid acids as catalysts. The focus is on the similarities and differences between the liquid acid catalysts on one hand and solid acid catalysts, especially zeolites, on the other. Thus, the reaction mechanism, the physical properties of the individual catalysts, and their consequences for successful operation are reviewed. The final section is an overview of existing processes and new process developments utilizing solid acids.

The biblical Old Testament period overlaps with the Copper, Bronze, and Iron Ages, so it is natural that these metals are mentioned frequently in the Bible and in other ancient manuscripts. For example, iron is mentioned about 100 times in the Old Testament, copper 8 times, and bronze more than 150 times. Other metals that were easily obtained (tin and lead) are also described numerous times. In fact, production of metals has been a significant factor in technology and chemistry for many centuries. Processes that are crude by modem standards were used many centuries ago to produce the desired metals and other materials, but the source of raw materials was the same then as it is now. In this chapter, we will present an overview of inorganic chemistry to show its importance in history and to relate it to modern industry.

In this paper we shall review these tremendous accomplishments, paying particular attention to the processing economics and process technology and chemistry. Some statistical information regarding the catalysts employed will also be presented together with an over-all look at future uses of catalytic methods in the petroleum industry.

Sodium is the alkali metal, the chemical properties of which are best established in the molten state. Lithium chemistry has been improved during the last decade due to the interest of the fusion reactor technology. Nevertheless, several chemical properties are still unknown. Potassium and the heavy alkali metals still require research work concerning the solutions of their compounds with non-metals, as well as on the solu-bihty of metallic elements. The solubility of transition elements may range at the same level as in sodium. The degree of solubility of the elements of the fourth and fifth groups and the formation of intermetallic compounds with them are not well known. Further research may detect some new aspects, which may help to improve the application of liquid alkali metals in modem technology and chemistry. 

Zeolites are crystalline alumino silicates with internal voids, channels or cavities, denoted, according to lUPAC, as micropores below 2mn and mesopores between 2 and 50 nm. These pores give zeolites a place of choice for nanometric technology and chemistry. They can contain (and protect) metallic nanoparticles or nanometric molecular complexes. Zeolites can protect metals from sintering. Up to a certain...

Tests performed outside clinical laboratories are attracting increasing interest. Complex technology and chemistry are combined in easy-to-use machines dry-film technology is the commonest technique used. The philosophy is that economically the immediacy of the result offsets the high consumables costs. For many analytes there is no need for such immediacy however, patients can perform their own home glucose monitoring, GPs and others may offer cholesterol analysis as part of an assessment of cardiovascular disease, and intensive therapy units in hospitals invariably have blood gas machines to hand.
