Available in PDF, EPUB and Kindle. Book excerpt: Originally published in the early 20th century, this book provides a comprehensive overview of the science and technology of coal-tar and ammonia, two key chemical products of the industrial era. Lunge's lucid explanations and detailed illustrations make this a valuable resource both for historians of science and for chemists seeking to deepen their understanding of these important compounds.

Excerpt: ...most part formed during the process of distillation itself; but this view cannot be maintained in face of the smooth synthesis from toluene-styrene by Kraemer and Spilker. Kraemer (priv. comm.) states that the above observation cannot be correct; by overheating phenol mere traces of anthracene are formed. Zmerzlikar Z. angew. Chem., 1895, p. 468) denies the possibility of the formation of anthracene by the overheating of phenols. Anthracene has also been found in that peculiar greasy substance called "stupp," which is formed in the distillation of mercury from its ores (G. Goldschmidt and M. von Schmidt). Its preparation from the highest-boiling constituents of coal-tar, and the analysis of crude anthracene, will be minutely described in a separate chapter later on (Chapter VII.). The preparation of chemically pure anthracene (which is not a commercial article) is not easy, unless crude anthracene 1 Ber., 1885, p. 859. distilled over caustic potash can be employed. From this, by one washing with carbon disulphide and several recrystallizations from petroleum spirit, pyridine or benzene, beautiful white scales with blue fluorescence are obtained, which it is very difficult to obtain from ordinary crude anthracene. This is best accomplished after subliming this at the lowest possible temperature and washing with ether to remove yellow colouringmatters; or it is dissolved in benzene and bleached by sunlight, in which case a little paranthracene is always formed. The safest way to obtain chemically pure anthracene is to reduce its derivatives by zinc-dust.1 Pure anthracene forms shining white scales (clinorhombic prisms) with purple fluorescence. It fuses at 210 (Fritzsche, Berthelot), or 213 (Graebe and Liebermann), or 2i6-5...

Not illustrated. 1887 edition. Excerpt: ...I give them in what appears to me to be the order of their importance: --"1st. A physical action. A very greatly increased solidity is effected by choking up the pores, thus agglutinating the whole. mass of the wood into a more or less solid block. Apart from its rendering the wood more solid, this physical action is important in preventing the subsequent absorption of moisture. "2nd. A physiological action. The smell of the creosote imparted to the wood prevents germinal life, well known to be destructive to timber, from being developed within it. Seeing that the preservation of timber has been effected by such materials as chloride of zinc, sulphate of copper, &c., with greater or less success, and that the action of these bodies must be mainly, although I admit not entirely, dependent on their toxic properties, this physiological action is one of importance. It must be remembered, moreover, that creosote has the advantage of a well-marked smell, which odour most of the lower animals dislike. In this respect it is superior to the other bodies I have named. "Further, it is worth pointing out that all the constituents of the coal-tar, and not the tar-acids only, have a more or less wellmarked tarry odour. "3rd. A chemical action. Respecting the chemical action, I would draw attention to the fact that tar-acids are not only antiseptic, but that they possess the power of coagulating albumen. It is to this latter action that I shall have to refer later on in this Report, as playing an important part, in my opinion, in the preservation of the timber. "Now, the two following questions arise: --(1 st) Upon what constituents of the creosote does its value specially depend, and what are the relative values of its...

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Coal-Tar and Ammonia, Vol. 1 The last edition of this treatise appeared in 1900. I had for that edition enjoyed the co-operation of Dr H. Kohler - a gentleman actively employed in the industry of tar-distilling and already known in the literary field. A new issue having become necessary, the text of the last edition was thoroughly overhauled and completed by the vast amount of fresh matter accumulated in the interval. For the major part of this new edition - viz., all the chapters dealing with Coal-tar and the products made therefrom (Chapters I. to XI.) - I have this time been favoured with the services of one of the greatest authorities in that domain, Dr G. Kraemer of Berlin, who has had the great kindness to look over the proofs and to give me the benefit of corrections and additions taken from his vast experience. I therefore indulge in the hope that this fourth edition will meet with the same favourable reception as its predecessors, and will prove of use to all interested in the industries described here.
