Industrial chemicals unique aspects

Recently, tetrafunctional initiators have also been introduced for styrenics. In 2001, Atofina Chemicals introduced a novel tetrafunctional initiator, Luperox JWEB50, developed specifically for the styrenics industry to produce high molecular weight, high-heat, crystal polystyrene with improved productivity in a cost-effective manner. JWEB50 is a room temperature stable, liquid peroxide with a half-life similar to those of currently used cyclic perketals, appropriate for use in mass polystyrene processes. A unique aspect of... 

Because of the widespread industrial interest these catalysts have engendered, the majority of the literature to be cited is in the form of patents or published patent applications." When a published patent application has been subsequently issued as a U.S. Patent, the U.S. Patent number will be cited. When an equivalent application appears to a published PCT International Application in Japanese, the English-language version will be cited. Japanese laid-open applications (Kokai) will be addressed to the extent that the abstract gives a clear picture of the unique aspect of the invention. Chemical Ah stracts accession numbers will be provided for all cited patent literature.

Sustained mutual growth and interdependence of the chemical and information communities should take account of several unique aspects of the chemical sciences. These include extensive and complex databases that characterize the chemical disciplines the importance of multiscale simulations that range from molecules to technological processes the global economic impact of the chemical industry and the industry s major influence on the nation s health, environment, security, and economic well-being. In planning the future of the chemical... 

Each chemical industrial facility is unique with respect to age, operation, and complexity. Another aspect to be considered relates to the chemical processing system. This... 

The basis of chemical engineering is application of scientific and engineering principles to solve problems of industrial and societal importance. Chemical reaction engineering is unique to chemical engineering and is at the core of its identity as a separate discipline because it combines chemistry, chemical kinetics, catalysis, fluid mechanics, and heat and mass transfer. Other disciplines involve some of these aspects, but none brings the reaction chemistry and the transport together in the same way. 

Because of its unique chemical and physical properties, elemental sulfur has interesting potential applications, par-ticularly in the construction industry. Despite years of research and developmental activities, little sulfur has been consumed in these applications. One reason for this is that sulfur atoms combine with each other to form the extremely complicated and complex system of chain or ring molecules, Sx. Depending on x, the physical and chemical properties of sulfur molecules and the molecular equilibria mixtures change rather drastically. For practical applications, the correlations between molecular size, molecular geometry, chemical and physical stability, and other common properties of sulfur must be known. Stereochemical aspects may indicate the performance of Sx in different applications. 

The contents of Chemical and Engineering News are well known. The OiZ, Paint Drug Reporter is perhaps unique. This weekly records general news of most kinds. It reports on chemicals by departments. This means that stress is placed upon editorial comment and trade opinion on both industry and specific chemical levels. Summaries of recent events appear also, but accounts are short and in newspaper style. Chemicals are but one interest of the Journal of Commerce and treatment is not so systematic. News summaries, when they appear, are often more detailed. Both the chemical and industry aspects are given. The other members of the leading six journals (Table II) are... 

Building on current initiatives and leveraging partnerships, this unique work provides practical mechanisms to help managers understand how to recognize and monitor the value of sustainability in their decisions. The work focuses on operational aspects, decision support, practical tools for measuring progress, and case studies of barriers and opportunities associated with the pursuit of corporate sustainability - all with a look to the chemical industry.
