Production of Sorbitol by Use of Ammonia Synthesis Gas

N2 - Introduction Photosynthesis is typically understood as the light-dependent production of sugar from carbon dioxide (CO2). The endosymbiotic chloroplast is the cellular location for most of this metabolism in plants, but some additional metabolism occurs in the cytosol to make the sugars that will be transported around the plant, mainly sucrose and also sugar alcohols, such as sorbitol and manitol. There are many processes that can properly be called photosynthesis, but a core set of processes underlie most of the considerations in this book. This chapter will provide an overview of those processes, and many topics covered in this chapter are the subject of more in-depth chapters later on. This chapter begins by describing the initial capture and temporary storage of light energy as highly reactive molecules (nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP)) on carbon. By reducing (i.e., by adding electrons to) carbon from its most oxidised state (CO2) to the status of sugars (CH2O)n, the energy initially stored as NADPH and ATP can be stored on the carbon. Additional energy can be stored on each carbon atom by reducing it fully, as happens in the synthesis of oils (R-CH2-R), but this is generally not considered when describing photosynthesis. Finally, issues surrounding uptake of the CO2 will be addressed. Photochemistry Synopsis Photochemistry, the capture of light energy and its conversion to chemical energy suitable for reducing CO2 to sugar, is the source of nearly all energy available to living things. Energy captured by absorbing molecules is stored as the high-energy intermediates NADPH (reducing power) and ATP (sometimes called the energy currency of the cell).

Sara Iborra was born in Carlet (Spain) in 1959. She studied Pharmacy at the Universidad de Valencia and received her Ph.D. in 1987. In the same year, she joined the chemistry department of the Technical University of Valencia as Assistant Professor, becoming Lecturer 1992 at the same department where she teaches organic chemistry. In 1991, she was appointed member of the Institute of Chemical Technology, a joint center of the Spanish National Research Council (CSIC) and the Technical University of Valencia where she joined the research group of Professor Avelino Corma. The main focus of her work is the application of heterogeneous catalysts (acid, base, and redox solid catalysts) in the synthesis of fine chemicals.

Occupational exposure to DMF may occur in the production of the chemical itself, other organic chemi cals, resins, fibres, coatings, inks, and adhesives (IARC, 1999). Exposure may also occur during use of these coatings, inks, and adhesives in the synthetic leather industry, in the tanning industry, and as a solvent in the repair of aircraft (Ducatman et al., 1986; IARC, 1989).

In 1996, just over 16 tonnes of DMF were released from various industrial locations in Canada, of which 93% (15 079 kg) were emitted to the atmosphere and the remainder to water (245 kg), wastewater (204 kg), landfill sites (26 kg), or deep-well injection (669 kg) (Environment Canada, 1998). The Canadian market for DMF is quite small, with an estimated domestic con sumption in the range of less than 1000 tonnes/year (SRI International, 1994; Environment Canada, 1998). The petrochemical sector was responsible for 84% (12.7 tonnes) of the reported atmospheric releases. Releases from the pharmaceutical industry accounted for 87% (0.212 tonnes) of total releases to water. Total release volumes from Canadian industrial sectors include 13.3 tonnes from the petrochemical sector, 1.2 tonnes from manufacture of pharmaceuticals, 0.7 tonnes from dye and pigment manufacture, 0.6 tonnes from polyvinyl chloride coating operations, 0.1 tonnes from its use as a solvent in pesticide manu facture, 0.07 tonnes from paint/finisher and paint remover manufacture, and 0.09 tonnes from other mis cellaneous industrial sectors.For 1996, a reported total quantity of 0.056 tonnes was released (0.023 tonnes to air, 0.033 tonnes to water) by the producer during chemical synthesis of DMF (Environment Canada, 1998). Less than 1 tonne of DMF was released from wastewater treatment facilities and in landfills (Envi ronment Canada, 1998). With a few exceptions, most industries reported little to no seasonal variation in releases (Environment Canada, 1998).
