Excerpt: ...closely related, as the formulae show: yC6H, NH2 yC, H4NHa HO(5--C H4NH2 C--CeHjNHa X6H4NH2 C6H4NHjCl Para-rosaniline Para-rosaniline hydrochloride (red dye) The theory of the structure of the benzene molecule put forward by Kekul6, and the elucidation of the constitution of rosaniline and para-rosaniline which it rendered possible, not only enabled one to understand the exact relations between the different dyes, the Hofmann violets, aniline blue, etc., which had already been prepared, but new and better processes for the synthesis of these and other dyes could be introduced. Thus the old process for the manufacture of para-rosaniline and rosaniline (magenta) has given place to the " New Fuchsine" process in which para-rosaniline is prepared from formaldehyde and aniline, while rosaniline is prepared from formaldehyde, aniline, and orthotoluidine. The hydrogen atoms of the three NH2-groups present in rosaniline and para-rosaniline can be replaced by various groups, such as methyl (CH3), ethyl (C2H6), phenyl (C6H5), benzyl (C6H5-CH2), etc., by acting on the compounds with methyl chloride, ethyl chloride, aniline, benzyl chloride, etc. In this way whole series of dyes can be obtained, like the Hofmann violets, which were prepared by replacing three hydrogen atoms in rosaniline by methyl or ethyl groups; and aniline blue, which is derived from magenta by the replacement of three hydrogen atoms by phenyl groups. Since, therefore, a varying number of hydrogen atoms can be replaced by different groups, it will readily be understood that from the' parent dye, magenta, quite a considerable number of derived dyes can be prepared. The production of the Hofmann violets, we have seen, involves the introduction of new reagents, methyl...

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 our 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 dis cuss in a readily intelligible manner the production and utilisation of coal tar, and to indicate, sufh ciently fully for the general reader, the almost infinite variety of materials - dyes, drugs, perfumes, explosives - for the manufacture of which coal tar is the raw material.
