Описание: Chromic acid [Cr(VI)] is an important and useful tool in the hands of chemists both for preparative and analytical purposes .It has been used to oxidize almost all organic and some inorganic compounds. Aromatic anils and substituted aromatic anils were prepared, characterized and the cooxidation of aromatic anils and oxalic acid by chromic acid in aqueous acetic acid medium proceeds much faster than that of either of the two substrates alone.The rate of the reaction increases when electron-releasing groups introduced on one ring or both rings of the anils whereas,electron-withdrawing groups decreasing the rate of oxidation at the same manner. The oxidation kinetics of aromatic anils by Cr(VI) in presence of oxalic acid in aqueous acetic acid follows first order in [oxidant] and fractional order in [substrate] and [oxalic acid] with the corresponding yields benzaldehyde and azobenzene. The rate of oxidation is enhanced with increasing concentration of hydrogen ions.Aluminium ions suppress the reaction. The intermediate is believed to be formed from aromatic anils and chromic acid-oxalic acid complex.Thus, this is a suitable mechanism proposed for the cooxidation reaction.

Описание: This book provides an overview on the molecular mode of action of carcinogenic polycylic aromatic hydrocarbons (PAHs). PAHs are by- products arising from incomplete combustion of organic matter that are frequently released into our environment, and thus are ubiquitously detectable.
Описание: Polycyclic aromatic hydrocarbons (PAHs) are the first type of chemicals that were ever discovered to cause cancer in humans. They are found in cigarette smoke, in barbecued and smoked foods, in automobile and Diesel engine exhaust, fireplace smoke, and many other common things that people are exposed to. Analyzing for PAHs in the environment is important in identifying potential sources of cancer exposure and eliminating these as risks. The smaller PAHs, those of lower than 300 molecular weight, have been the most studied and have also been covered in several books. No books have dealt with the analysis of the larger PAHs. These compounds are not only important for the health concerns, but they are also of current technological and scientific interest.

Описание: Heterocyclic compounds are of prime importance to organic chemists working in the chemical industry, and heterocyclic chemistry is therefore a fundamental topic in undergraduate chemistry courses. The emphasis of this short text is on synthetic aspects rather than properties, and it covers the essential details and basic principles with reference to all the important classes of heterocyclic compounds. Instructional problems are included as an aid to comprehension, and references to more detailed texts are provided.

Описание: Presents accounts of current research in polynuclear aromatic compounds, showing examples of studies both of pure compounds and of complex, fossil fuel related mixtures. Offers a thorough knowledge of aromatic chemistry through coverage of reduction, oxidation, and thermal reactions--including applications developed for both coal and petroleum materials. Featured topics include quantum chemical structure-reactivitylationships, spatial configurations of large polynuclear hydrocarbons, cyclophanes, and desulfurization of heterocycles. Scientists studying all aspects of the chemistry of polynuclear aromatics will discover important, pertinent information in this volume.
Описание: Recent significant advances with transition-metal-mediated reactions have opened promising new routes to complex aromatic compounds and have been the subject of intense research in recent years.
Описание: Polycyclic Aromatic Compounds (PAC) are a broad class of compounds whose wide distribution in the environment results from incomplete combustion processes of fossil fuels in power generator, industrial plant and domestic heating, from car exhaust gas and from tobacco smoke.
