Book excerpt: Excerpt from The Chemistry of the Coal-Tar Dyes This book is Intended for those students and dyers who have a good knowledge of general chemistry, and some knowledge of organic chemistry. The object is to present, briefly, the origin and history of coat-tar production, and a discussion of the intermediate products between the coal-tar and the dyes themselves. The methods of making the dyes are taken up, followed by a study of the relations of the great classes of dyes, and also the individual dyes themselves, to one another in the same class. The development of one color from another by a change in its composition is explained, and tables showing the variation of color accompanying change of composition are included. The proof of constitution is in many places given in such detail as to allow the student to comprehend the bases for the structure of the complex molecules of the dyes. The significance of the chromophors and chromogens in the different classes of dyes is discussed. The use of mordants and the character of the union between the dyes and animal and vegetable fibres are also included. A few manufacturing processes are introduced here and there in detail, to give clear conceptions of this phase of the subject. Some practical experience to assist in comprehending the theory of the subject is made possible by a course of experiments, the performance of which aids in vivifying this difficult and interesting subject. It is hoped that this feature of the work will produce a more tangible result than could otherwise be possible.
