Reporting Using Technology

Initial production of the dimethyl terephthalate started with the oxidation of -xylene to terephthaUc acid using nitric acid both companies reportedly used similar technology (43—45). Versions of the nitric acid oxidation process, which has been abandoned commercially, involved the use of air in the initial oxidation step to reduce the consumption of nitric acid (44,46,47). The terephthaUc acid was then esterified with methanol to produce dimethyl terephthalate, which could be purified by distillation to the necessary degree (48). 

HSTAT is a free, Web-based resource that provides access to full-text documents used in healthcare decision-making.14 These documents include clinical practice guidelines, quick-reference guides for clinicians, consumer health brochures, evidence reports and technology assessments from the Agency for Healthcare Research and Quality (AHRQ), as well as AHRQ s Put Prevention Into Practice.15 Simply search by isobutyryl-CoA dehydrogenase deficiency (or synonyms) at the following Web site http //text.nlm.nih.gov. 

The clean and efficient production of azo dyes is a classical chemistry problem. The manufacture of this industrially important family of compounds is traditionally associated with the additional formation of large quantities of hazardous and colored waste. A method for the construction of both phenolic and amino azodyes has been reported using a polymer-supported nitrite reagent to effect diazoti-zation of aromatic amines (Scheme 2.53) [80]. Waste minimization and operational simplicity, along with improved separation technologies, are key advantages of polymer-supported reagents in this area. 

Internationally, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) periodically considers food additives, including antioxidants, on the basis of all available scientific data to establish acceptable daily intake levels (92) and specifications on the identity and purity of the additives. The conclusions of JECFA are published in numerous reports and technological summaries by the World Health Organization (WHO) as the WHO Technical Report Series and WHO Food Additives Series. Such information provided by JECFA is used by the Joint FAO/ WHO Codex Alimentarius Commission in implementing the Joint FAO/WHO Standards Program, which was established to elaborate international standards for foods to protect the health of consumers, to ensure fair practices in food trade, and to facilitate international trade (90). 

Plasma-jet diamond techniques yield growth rates of about 980 tm/h (163,164). However, the rate of diamond deposition is still one to two orders of magnitude lower than the HP—HT technology, which is about 10,000 tm/h (165). Diamond deposition rates of ca 1 Jim/s have been reported using laser-assisted techniques (166). This rate is comparable to the HP—HT synthesis.
