Excerpt from Compound Formation in Phenol-Cresol Mixtures: Dissertation Submitted in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Pure Science in Columbia University In a series of communications in the past few years1 addition compound formation in a large number of binary systems has been investigated, particular attention being paid to variations in the extent of compound formation as the constituent radicals of the components were varied. In all more than 100 new compounds have been isolated and simple and definite rules regarding the rela tive stability of addition compounds in solutions have been derived. It has been shown that the extent of addition compound formation in binary mixtures is controlled primarily by the chemical con trast, with the stability of complexes increasing uniformly with the differences in character the positive or negative nature of the constituent groups) of the two compounds.

The chemistry of phenols tends to be ignored in organic chemical textbooks and to be lost amongst the many classes of functional derivatives. This volume is not intended to provide a textbook approach but rather to give an account of developments in phenol chemistry in the last two decades. Features of this book: • Numerous phenolic systems have been covered in detail, e.g. phenolic propanoids. • The emphasis throughout has been on synthesis, on what can be achieved by the use of phenolic intermediates and in the construction of phenolic end products. • Many chapters enable the reader to refer to the original literature wherever possible. • Various chapters provide a fund of tutorial material and problems for undergraduate studies and further, which will encourage perusal of the literature. Some 2000 references to applied and academic papers are given. Phenols are ubiquitous substances and now it is more widely accepted that there are pros and cons connected with their usage. The pros for compounds are well-known and are illustrated by perennial panaceas such as aspirin, paracetamol, codeine, etc. The cons are less obvious because they are also materials deeply entrenched in our standard of living and in most cases inherent hazards have only recently come to light. The book will be of interest to postgraduate students in academic and industrial work.

The seventh edition of this classic reference work once more provides a comprehensive overview of commercially available plastics materials. Bridging the gap between theory and practice, it enables scientists to understand the commercial implications of their work as well as providing technologists with a theoretical background. Since the previous edition, several new materials have been announced. Many of these materials result from metallocene catalyst technology. In addition, developments also continue with condensation polymers with several new polyester type materials of interest for bottle-blowing and/or degradable plastics. New phenolic-type resins have also been announced. As with previous editions, an explanation of the properties of these new materials in terms of their structure and morphology involving the principles laid down in the earlier chapters is presented.

The book provides fundamental chemistry and properties of near-critical water (NCW) and supercritical water (SCW), criteria and challenges/solutions in reactor design for NCW and SCW processes, and up-to-date reviews and practice of a wide range of their applications in bio refineries including: production of hydrochars from biomass, SCW oxidation (SCWO) for waste treatment, SCW gasification (SCWG) of biomass and waste for hydrogen and methane production, hydrothermal liquefaction of biomass, production of chemicals and SCWO of biofuels for energy. It also presents techno-economic analysis of hydrogen production via SCWG of biomass. The book will be highly essential for both academic researchers and industrial practitioners for developing novel bio refinery technologies and processes employing NCW or SCW for treatment of various organic waste streams and production of bio-energy and bio-based chemicals from bio-renewable resources. Prof. Dr. Zhen Fang is leader and founder of biomass group, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, China. Dr. Chunbao (Charles) Xu is currently an Associate Professor of Chemical Engineering and NSERC/FP Innovations Industrial Research Chair in Forest Bio refinery at Western University, Canada.

Nitration of Hydrocarbons and Other Organic Compounds tackles various concerns in the process of substituting hydrogen atoms in the aromatic or heterocyclic nucleus, or in saturated hydrocarbon, by nitro groups. The title first covers the nitration of aromatic and heterocyclic compounds with nitric acid and nitrating mixture, and then proceeds to discussing the mechanism of the nitration of aromatic compounds with nitric acid and nitrating mixture. Next, the selection deals with the nitration of saturated, aromatic-aliphatic and unsaturated hydrocarbons with nitric acid. The text also talks about the nitration with nitrogen oxides, along with the nitration of amines. The last chapter details the nitration of organic compounds with organic and inorganic nitrates and nitroxyl. The book will be of great interest to students, researchers, and practitioners of organic chemistry.

This unique volume covers the results of the world-wide efforts to implement natural polymers as engineering plastics and the use of their inherent properties. The processing opportunities and the applications of the natural materials as reinforcement of polymer composites are discussed, including the structural, morphological and thermal characterization as well as the mechanical behavior of the obtained materials. Also covered is the preparation of biodegradable homopolymers, blends and composites, which involves chemical reactions, regardless of the type of the starting material.
