By some measure the most widely produced chemical in the world today, sulfuric acid has an extraordinary range of modern uses, including phosphate fertilizer production, explosives, glue, wood preservative and lead-acid batteries. An exceptionally corrosive and dangerous acid, production of sulfuric acid requires stringent adherence to environmental regulatory guidance within cost-efficient standards of production.

This work provides an experience-based review of how sulfuric acid plants work, how they should be designed and how they should be operated for maximum sulfur capture and minimum environmental impact. Using a combination of practical experience and deep physical analysis, Davenport and King review sulfur manufacturing in the contemporary world where regulatory guidance is becoming ever tighter (and where new processes are being required to meet them), and where water consumption and energy considerations are being brought to bear on sulfuric acid plant operations. This 2e will examine in particular newly developed acid-making processes and new methods of minimizing unwanted sulfur emissions.

As pharmaceutical companies look to develop single enantiomers as drug candidates, chemists are increasingly faced with the problems associated with this subclass of organic synthesis. The Handbook of Chiral Chemicals, Second Edition highlights the problems associated with the production of chiral compounds on a commercial scale.

The handbook first elaborates upon starting materials obtained from a "chiral pool," which can be derived from natural products. Then it explains methods and reactions that can introduce or influence stereogenic centers, particularly asymmetric hydrogenations, oxidations, pericyclic reactions, and enzymatic methods. While hydrogenations have been the most widely employed approach for the large-scale synthesis of several commercial compounds, the search for the ideal catalyst has consistently led researchers to enzymes present in biological systems. Several chapters concentrate on understanding how to manipulate enzymes for catalyzing new reactions for taking new substrates. Other significant topics include chiral auxiliaries, chromatographic techniques, enantiomers-specific reactions, and resolution.

This second edition updates all its chapters, illustrating the speed of development in this field, and features new chapters that highlight successful approaches in an industrial setting. The Handbook of Chiral Chemicals, Second Edition is a guide to advances in the field that result in more efficient and cost-effective synthesis of chiral chemicals.

The first comprehensive guide to the chemicals and gases used in semiconductor manufacturing

The fabrication of semiconductor devices involves a series of complex chemical processes such as photolithography, etching, cleaning, thin film deposition, and polishing. Until now, there has been no convenient source of information on the properties, applications, and health and safety considerations of the chemicals used in these processes. The Handbook of Chemicals and Gases for the Semiconductor Industry meets this need.

Each of the Handbook’s eight chapters is related to a specific area of semiconductor processing. The authors provide a brief overview of each step in the process, followed by tables containing physical properties, handling, safety, and other pertinent information on chemicals and gases typically used in these processes. The 270 chemical and gas entries include data on physical properties, emergency treatment procedures, waste disposal, and incompatible materials, as well as descriptions of applications, chemical mechanisms involved, and references to the literature. Appendices cross-reference entries by process, chemical name, and CAS number. The Handbook’s eight chapters are:

• Thin Film Deposition Materials
• Water Cleaning Chemicals
• Photolithography Materials
• Wet and Dry Etching Materials
• Chemical Mechanical Planarizing Materials
• Carrier Gases
• Uncategorized Materials
• Semiconductor Chemicals Analysis

No other single source brings together these useful and important data on chemicals and gases used in the manufacture of semiconductor devices. The Handbook of Chemicals and Gases for the Semiconductor Industry will be a valuable reference for process engineers, scientists, suppliers to the semiconductor industry, microelectronics researchers, and students.

In addition to capillary gas chromatography and GC-MS, carbon-13 NMR spectroscopy provides an alternative method for essential oils analysis. The excellent visual spacing of the signals enables oil samples to be analyzed without preliminary separation of their components. Also, information relating to the molecular structure of the oil constituents can be ascertained from the measured chemical shifts. This second edition clearly demonstrates the power of the technique in the characterization of essential oils, based on 60 sample oils chosen for their industrial importance together with the 188 carbon-13 NMR spectra of significant components. Supporting data are presented using capillary gas chromatography.

Key features of the Second Edition:

• 18 new essential oils are included, five oils are replaced and five oils with less or little importance are deleted
• Revision of numerous analyses taken over from the 1st edition
• Capillary gas chromatograms of 60 commercially important essential oils
• Qualitative and quantitative analytical results of those essential oils
• Carbon-13 NMR analyses of those essential oils without separation of their components
• Carbon-13 NMR spectra of 188 most important oil constituents are given (67 are new in the 2nd edition)

This collection of ¹³C NMR and GC data is aimed at essential oils and natural products chemists, NMR research groups, university departments of chemistry, pharmacy, botany, and food science, as well as those working in the essential oils, perfumes, flavours and food technology industries.

This book is a "world first," since the furfural industry has been traditionally secretive to the point of appearing shrouded in clouds of mystery. Even renowned encyclopedic works have published but scant and often erroneous information on the subject.
Striking a healthy balance between theory and practice, the book leads the reader from reaction mechanisms and kinetics to the technology of making furfural by various old and new processes, using conventional raw materials or sulfite waste liquor. Detailed discussions of means of increasing the yield are of great chemical and technological interest as well as of immense economic importance.
From furfural proper, the treatise shifts to the fascinating field of wanted and unwanted by-products ranging from largely unutilized carboxylic acids to troublesome impurities such as 5-methyl furfural and 2-furyl methyl ketone, and then to extremely valuable serendipitous flavor compounds such as diacetyl and 2,3-pentanedione. A wide variety of derivatives are discussed; considerable space is devoted to polytetrahydrofuran, an important building block of stretchable synthetic fibers, while furan resins from both furfural and furfuryl alcohol are given the attention commensurate with their industrial importance.
Notable supplementary chapters cover the in-line measurement of furfural, the treatment of furfural waste water, and various aspects of corrosion. A chapter on the applications of furfural elaborates not only traditional uses in extracting petroleum and vegetable oils but also the sensational discovery that furfural is a highly effective "indirect nematocide." Without becoming toxic, it changes the microflora of the soil by stimulating bacteria antagonistic to nematodes, thereby reducing the nematode population to zero, at an unprecedented low price. It is believed that this application will be the principal outlet for furfural in the future.
A comprehensive list of physical properties, some never published before, make the book an indispensable companion for producers, users and researchers alike.
