Glucose chemical intermediates

Dupont has also been active in developing chemical intermediates based on natural materials. The most prominent example is glucose-derived 1,3-propanediol, a raw material for polymethylene terephthalate, a polyester with promising applications as... [Pg.79]

On the other hand, the six-carbon unit of glucose is one of the most prominent components in biomasses, is easy to produce, and represents one of the most attractive building blocks for the preparation of a variety of chemical intermediates. Thus, glucose will play a central role in feeding the so-called biorefinery, a future plant where chemical and biochemical processes are advantageously employed for the synthesis of intermediates and fine chemicals as an alternative to fossil-derived chemicals (Figure 21.1). [Pg.349]

The oxidation of glucose, a cheap and renewable starting material, represents a challenging target for chemical intermediates, mainly when clean technologies can be apphed. [Pg.448]

Chemical intermediates, such as catechol and adipic acid, used in the manufacture of nylon-6,6, polyurethane, lubricants, and plasticizers are normally derived from petroleum-based benzene and toluene. Airborne benzene causes cancer and leukemia toluene leads to brain, liver, and kidney damage, and debilitates capacity for speech, vision, and balance. Researchers at Michigan State have developed a green method for biosynthesizing catechol and adipic acid from glucose, rather than from benzene and toluene, using genetically altered E. coli ... [Pg.6]

Heterogeneous catalysts, particularly zeolites, have been found suitable for performing transformations of biomass carbohydrates for the production of fine and specialty chemicals.123 From these catalytic routes, the hydrolysis of abundant biomass saccharides, such as cellulose or sucrose, is of particular interest. The latter disaccharide constitutes one of the main renewable raw materials employed for the production of biobased products, notably food additives and pharmaceuticals.124 Hydrolysis of sucrose leads to a 1 1 mixture of glucose and fructose, termed invert sugar and, depending on the reaction conditions, the subsequent formation of 5-hydroxymethylfurfural (HMF) as a by-product resulting from dehydration of fructose. HMF is a versatile intermediate used in industry, and can be derivatized to yield a number of polymerizable furanoid monomers. In particular, HMF has been used in the manufacture of special phenolic resins.125... [Pg.69]

Historically, the target analytes in clinical mass spectrometric applications were small, volatile compounds that could be analyzed by GC-MS (see Chapter 4). With time, new chemical preparation techniques and derivatization schemes broadened the scope of these metabolites to include fatty acids, amino acids, intermediates of glucose oxidation, phospholipids, steroids, neurogenic amines, nucleic acids, etc. The molecular weights (molar masses) after derivatization were less than 1000 Da, a mass range easily within the limits of most conventional mass spectrometers. [Pg.288]

In contrast to experiments which attempted to identify phosphorylated intermediates on the look and see what is there basis, others were designed to investigate possible pathways of glucose breakdown suggested from its known chemical reactivity. Treating glucose in vitro... [Pg.51]
