This book was released on 2015-06-30 with total page 514 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Excerpt from Certification of Coal-Tar Food Colors Upon receipt of the sample and properly executed affidavits and agreement by the Bureau of Chemistry, the sample is examined chemically if the foundation affidavit indicates that the dye is of proper identity and fiurity. If the results obtained substantiate the claimed identity of t e dye and its com lianc'e with the standards of purity, a certificate assi ning a lot num er to the batch is'issued by the bureau to the manu acturer. If the bureau's examination shows that the product does not conform to the requirements for certifica tion, the batch is rejected for use in foods. The chemical examina tion and the certification or rejection of the batch usually take approximately two weeks.

This book was released on 2017-10-23 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Coal-Tar Colors Used in Food Products For the purposes of the investigation reported in the following pages, the legitimacy of the coloring of food and food products under certain conditions is regarded as established; the ethical and dietetic aspects of the question of food coloring are not here considered. The means at hand for coloring food products may be conveniently classified as vegetable, animal, mineral or inorganic, and synthetic or so-called coal-tar colors or dyes. Representatives of each of these have at one time or another all been used in the coloring of food, and the laws of various European and American States have, from time to time prohibited the use of certain specified members or all of each or some of the foregoing classes. It is therefore obvious that even for the legitimate purposes for which food can be colored, improper means are at command, and some of these, if not all, have been prohibited by law at some time or another.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Treasures of Coal Tar In order that the effort now being made to promote the more widespread application of science, and more especially to render this country independent of others for the supply of the dyes necessary for the maintenance of om textile industry, shall not be relaxed, it is essential that the people as a whole should interest themselves in the work, and should gain some knowledge of what has been achieved in the past, and some understanding of the nature and complexity of the problems to be solved. As the matter is urgent, and of vital importance for the welfare of this country, the writer felt that, even in a time of much preoccupation, he could not refuse the invitation of the publishers to discuss in a readily intelligible manner the production and utilisation of coal tar, and to indicate, sufffiently fully for the general reader, the almost infinite variety of materials dyes, drug, perfumes, explosives for the manufacture of which coal tar is the raw material.

No systematic account of the process of manufacture, or chemical relationships of the colours, has been attempted, but, as far as it has been possible to obtain the information, the chemical composition, formula, method of making, date of introduction, literature relating to it, and its discoverer have been given, while the properties and uses of the colours have had special attention paid to them.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Application of the Coal Tar Dyestuffs: The Principles Involved and the Methods Employed The rapid development of Applied Chemistry in recent years has brought about a revolution in all branches of technology. This growth has been accelerated during the war, and the British Empire has now an opportunity of increasing its industrial output by the application of this knowledge to the raw materials available in the different parts of the world. The subject in this series of handbooks will be treated from the chemical rather than the engineering standpoint. The industrial aspect will also be more prominent than that of the laboratory. Each volume will be complete in itself, 'and will give a general survey of the industry, showing how chemical principles have been applied and have affected manufacture. The influence of new inventions on the development of the industry will be shown, as also the effect of industrial requirements in stimulating invention. Historical notes will be a feature in dealing with the difierent branches of the subject, but they will be kept within moderate limits. Present tendencies and possible future developments will have attention, and some space will be devoted to a comparison of industrial methods and progress in the chief producing countries. There will be a general bibliography, and also a select bibliography to follow each section. Statistical information will only be introduced in so far as it serves to illustrate the line of argument.
