Abstract

This volume is divided into nine chapters, each by a separate author except two, which have been prepared by the same writer. The chapters are entitled Hydrocarbons; Bitumens; Naphthalene and Its Derivatives; Anthracene and Its Associates; Phenols; Aromatic Acids; Gallic Acid and Its Allies; Phthalic Acid and the Phthaleins, and Modern Explosives. The chapters on phenols and aromatic acids, which include benzaldehyd, salicylic acid and related compounds and benzoic acid and its esters, are of value to those interested in medicinal chemistry. In these sections much attention is given to the detection and determination of saccharin, vanillin and coumarin in foods and beverages. The Rideal-Walker and the Hygienic Laboratory methods for determining the phenol coefficient of antiseptics are given in full, and the difficulties in carrying out each are discussed. While much new material has been added in the revision, numerous subjects properly belonging in the classification are but briefly
