Book Description

Excerpt from The Silicates: In Chemistry and Commerce, Including the Exposition of a Hexite and Pentite Theory and of a Stereo-Chemical Theory of General Application In the year 1903, Faculty of Philosophy in the University of Gottingen proposed the following thesis in connection with the Benek Bequest: A critical examination, based on experimental evidence, is to be made of such chemical compounds as cannot be satisfactorily explained by the usual means. This examination should also take into special consideration the extent to which the introduction of molecular additions is of importance in the formation of such compounds, and whether it is possible to devise a complete systematic arrangement of such compounds. The solution of the problem was admittedly incomplete, inasmuch as only a single branch of the subject - the silicates - was taken into consideration. For this reason the Faculty did not grant the first prize to this thesis, but readily granted the second prize "in recognition of fruitful labours leading to a single theory covering a very important group of complex compounds." In this way an established theory - the Hexite-Pentite Theory - was devised for one highly important group of complex compounds - the silicates. With this theory in mind, it was only natural to apply it to a series of silicates of technical and commercial value, such as the ultramarines, Portland, slag, dental and other siliceous cements, glass, glazes, porcelain, etc., in order, if possible, to elucidate their constitution. This has been effected since the original thesis was first written, and the results are published in the following pages. Commencing with the assumption that Nature has formed all substances in accordance with monistic laws, the Hexite-Pentite Theory has also been applied to the study of the structure of other complexes as well as to that of solutions of the simpler acids, etc., and it has also been employed, in connection with the constitution of organic compounds, to form a bridge between organic and inorganic chemistry.
