Excerpt from The Examination of Hydrocarbon Oils and of Saponifiable Fats and WaxesThe fifth German edition was delayed iln publication until the close of the Great War, this, however, made it possible to present in its pages many of the important developments in oil chemistry brought out by the exigencies of the times. Thus it has been possible to discuss the chemistry of the various materials which were used by the German nation during the stress of war as substitutes for linseed-oil varnish, for resins, for cutting oils, for soaps, and for lubricants in general. New sections on electrical tests and various electrical phenomena, on heat of fusion, on graphite lubrication, on surface tension, on cumarone resins, on artificial resins and on rosin size have been introduced. Other chapters, such as those on viscosity, on the theory of lubrication, on calorimetric determinations, on turpentine and its substitutes, on wool grease, on cholesterin, and on soaps, have been reconstructed.In spite of simplification of text, tables and general arrangement of material, the new edition contains nearly 200 more pages, 19 more figures and 30 more tables than the fourth German edition.Each section of analytical procedure has again been preceded by a discussion of the industrial importance and technical use of the material in question, thus making the book, it is hoped, much more than a series of cook-book recipes. Many first class handbooks are available for a more detailed study of the individual subjects but the author has felt it inadvisable to omit or to shorten such theoretical or technical discussions. It is often impossible to interpret properly the results of an analysis unless such general information concerning the intended use of the material cis at the command of the analyst. Of course for a more detailed and more exact discussion of these general matters it will be necessary to consult the handbooks of industrial chemistry and various monographs of the separate industries.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
