| benzoic acid literature melting point: Benzoic Acid and Sodium Benzoate Axel Wibbertmann, World Health Organization, International Program on Chemical Safety, 2000 A concise assessment of the risks to human health and the environment posed by exposure to benzoic acid and sodium benzoate. Benzoic acid is used as an intermediate in the synthesis of several compounds, including phenol and caprolactam. The compound is increasingly used in the production of diethylene and dipropylene glycol dibenzoate plasticizers in adhesive formulations, and to improve the properties of alkyd resins for paints and coatings. Most releases of benzoic acid and sodium benzoate into the environment result from their use as preservatives in food, beverages, mouthwashes, dentifrices, and cosmetics. For sodium benzoate, the largest use is as an anticorrosive added to antifreeze coolants. Processed foodstuffs and soft drinks are considered the main sources of exposure for the general population. Concerning behavior in the environment, both compounds are readily biodegraded under aerobic conditions and are unlikely to bioaccumulate. In laboratory animals, exposure to high concentrations caused weight gain and adverse effects on the central nervous system, liver, and kidney. While data are limited, studies suggest that the compounds do not cause adverse effects on development or reproduction and are not carcinogenic. In humans, reports of adverse effects are largely confined to cases of urticaria, asthma, rhinitis, and anaphylactic shock following oral, dermal, or inhalation exposure to these compounds, including for medical purposes. No evaluation of long-term effects on health was possible in view of the limited data available |

| benzoic acid literature melting point: Mechanochemical Organic Synthesis Davor Margetic, Vjekoslav Štrukil, 2016-04-23 Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. - Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions - Integrates advances in green chemistry research into industrial applications and process development - Focuses on designing techniques in organic synthesis directed toward mild reaction conditions - Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds |

| benzoic acid literature melting point: Crystallization of Organic Compounds Hsien-Hsin Tung, Edward L. Paul, Michael Midler, James A. McCauley, 2009-06-17 Filled with industrial examples emphasizing the practical applications of crystallization methodologies Based on the authors' hands-on experiences as process engineers at Merck, Crystallization of Organic Compounds guides readers through the practical aspects of crystallization. It uses plenty of case studies and examples of crystallization processes, ranging from development through manufacturing scale-up. The book not only emphasizes strategies that have been proven successful, it also helps readers avoid common pitfalls that can render standard procedures unsuccessful. The goal of this text is twofold: Build a deeper understanding of the fundamental properties of crystallization as well as the impact of these properties on crystallization process development. Improve readers' problem-solving abilities by using actual industrial examples with real process constraints. Crystallization of Organic Compounds begins with detailed discussions of fundamental thermodynamic properties, nucleation and crystal growth kinetics, process dynamics, and scale-up considerations. Next, it investigates modes of operation, including cooling, evaporation, anti-solvent, and reactive crystallization. The authors conclude with special applications such as ultrasound in crystallization and computational fluid dynamics in crystallization. Most chapters feature multiple examples that guide readers step by step through the crystallization of active pharmaceutical ingredients (APIs). With its focus on industrial applications, this book is recommended for chemical engineers and chemists who are involved with the development, scale-up, or operation of crystallization processes in the pharmaceutical and fine chemical industries. |

| benzoic acid literature melting point: Detection and Identification of Organic Compounds Miroslov Vecera, 2012-12-06 The American edition of our monograph is not a mere translation of the Czech edition, which appeared some five years ago. We have had to respect the fact that even such a short period has sufficed for progress in this field, and that the field of application of methods of organic analysis has widened. We have therefore revised a number of chapters in Part 1, the general part of the monograph-mainly those devoted to chromatographic methods, which have been extended and complemented by methods of thin-layer chromatography and electrophoresis. The chapters on the theory of color reactions and on analytical literature have also been extended; the chapter on spectral methods has been extended by including the use of proton magnetic resonance in organic analysis, and the list of references has been enlarged by adding books of importance for organic analysis. In Part 2, the part dealing specifically with various elements and chemical groups, we have extended the chapters on solubility and on acids and bases. The methods for the detection and identification of given classes of compounds have also been supplemented by references to recent papers. |

| benzoic acid literature melting point: Compounded Topical Pain Creams National Academies of Sciences, Engineering, and Medicine, Health and Medicine Division, Board on Health Sciences Policy, Committee on the Assessment of the Available Scientific Data Regarding the Safety and Effectiveness of Ingredients Used in Compounded Topical Pain Creams, 2020-07-21 Pain is both a symptom and a disease. It manifests in multiple forms and its treatment is complex. Physical, social, economic, and emotional consequences of pain can impair an individual's overall health, well-being, productivity, and relationships in myriad ways. The impact of pain at a population level is vast and, while estimates differ, the Centers for Disease Control and Prevention reported that 50 million U.S. adults are living in pain. In terms of pain's global impact, estimates suggest the problem affects approximately 1 in 5 adults across the world, with nearly 1 in 10 adults newly diagnosed with chronic pain each year. In recent years, the issues surrounding the complexity of pain management have contributed to increased demand for alternative strategies for treating pain. One such strategy is to expand use of topical pain medicationsâ€medications applied to intact skin. This nonoral route of administration for pain medication has the potential benefit, in theory, of local activity and fewer systemic side effects. Compounding is an age-old pharmaceutical practice of combining, mixing, or adjusting ingredients to create a tailored medication to meet the needs of a patient. The aim of compounding, historically, has been to provide patients with access to therapeutic alternatives that are safe and effective, especially for people with clinical needs that cannot otherwise be met by commercially available FDA-approved drugs. Compounded Topical Pain Creams explores issues regarding the safety and effectiveness of the ingredients in these pain creams. This report analyzes the available scientific data relating to the ingredients used in compounded topical pain creams and offers recommendations regarding the treatment of patients. |
