Book Description
Alkylation process of iso-butane with butenes in the presence of concentrated sulfuric acid as catalyst is realized in film reactor to obtain high octane benzene. The popularity of this process can be explained in using cheap raw materials, produced in secondary processes of crude oil. In this paper, possible mechanisms of the process, and the conditions of their existence is shown. The influence of the temperature, isobutane-butene ratio, acid concentration, amount of dissolved organic substance in acid (red oil) etc. on the composition and the quality of the benzene is also discussed. It is established that the process does not depend on the hydrodynamics of the liquid phase. The induction period using pure sulfuric acid is very short. The benzene obtained in this process is comparable in all respect to that produced in commercial scale and is more economical.

Book Description
In recent years the need for sustainable process design and alternative reaction routes to reduce industry?s impact on the environment has gained vital importance. The book begins with a general overview of new trends in designing industrial chemical processes which are environmentally friendly and economically feasible. Specific examples written by experts from industry cover the possibilities of running industrial chemical processes in a sustainable manner and provide an up-to-date insight into the main concerns, e.g., the use of renewable raw materials, the use of alternative energy sources in chemical processes, the design of intrinsically safe processes, microreactor and integrated reaction/ separation technologies, process intensification, waste reduction, new catalytic routes and/or solvent and process optimization.

Book Description
Surfactants are used throughout industry as components in a hugerange of formulated products or as effect chemicals in theproduction or processing of other materials. A detailedunderstanding of the basis of their activity is required by allthose who use surfactants, yet the new graduate or postgraduatechemist or chemical engineer will generally have little or noexperience of how and why surfactants work. Chemistry & Technology of Surfactants is aimed at newgraduate or postgraduate level chemists and chemical engineers atthe beginning their industrial careers and those in later life whobecome involved with surfactants for the first time. The book is astraightforward and practical survey of the chemistry ofsurfactants and their uses, providing a basic introduction tosurfactant theory, information on the various types of surfactantand some application details. This will allow readers to build ontotheir scientific education the concepts and principles on which thesuccessful use of surfactants, across a wide range of industries,is based.

Book Description
The fifth edition of the Kirk-Othmer Encyclopedia of Chemical Technology builds upon the solid foundation of the previous editions, which have proven to be a mainstay for chemists, biochemists, and engineers at academic, industrial, and government institutions since publication of the first edition in 1949. The new edition includes necessary adjustments and modernisation of the content to reflect changes and developments in chemical technology. Presenting a wide scope of articles on chemical substances, properties, manufacturing, and uses; on industrial processes, unit operations in chemical engineering; and on fundamentals and scientific subjects related to the field. The Encyclopedia describes established technology along with cutting edge topics of interest in the wide field of chemical technology, whilst uniquely providing the necessary perspective and insight into pertinent aspects, rather than merely presenting information. Set began publication in January 2004 Over 1000 articles More than 600 new or updated articles 27 volumes Reviews from the previous edition: "The most indispensable reference in the English language on all aspects of chemical technology...the best reference of its kind". —Chemical Engineering News, 1992 "Overall, ECT is well written and cleanly edited, and no library claiming to be a useful resource for chemical engineering professionals should be without it." —Nicholas Basta, Chemical Engineering, December 1992
