Book Description
Excerpt from Journal of the Chemical Society, 1906, Vol. 89: Transactions, Part II During the development of a more accurate method (denison and Steele, P/iil. Trans, 1906, 205, A, 449) than that previously adopted for the direct measurement of ionic velocities, we have repeatedly noticed that when certain salts were employed as indicators there was a constant retardation of the margin under observation. It had been previously pointed out (steele, Phil. Trans, 1901, 198, A, 105) that one of the necessary conditions for a constant margin-velocity was that the indicator should not undergo hydrolysis, and a number of cases of retardation referred to above have been traced to the fact that the indicators in question were somewhat hydro lysed. It occurred to us that the retardation might be capable of quantitative measurement, and might serve as a means of determining, at least approximately, the extent of hydrolysis of the indicator. Our anticipations have been more than realised, as we have found the above principle to be capable of development to an accurate method of measuring hydrolysis which can be carried out with considerable rapidity and in solutions of widely varying con centration.

Excerpt from Journal of the Chemical Society, 1907, Vol. 92: Abstracts of Papers on Organic Chemistry; Part I Catalytic Reactions at High Temperatures and Pressures. X. Influence of Pressure. Wladimir N. Ipatieff (j. Russ. Phys. Chem. Soc., 1906, 38, i, 63 - 75. Compare Abstr., 1904, II, -at high pressures, the catalytic decomposition of alcohol with alumina as catalyst is considerably diminished, as Shown 1) by the slowness of the reaction, (2) by its remaining at the first stage, for example, 2etoh Z oet2 1120. The apparatus previously employed has now been SO modified that any quantity of gas can be forced into the reaction tube and its pressure determined, after which the tube can be disconnected from the gas supply and heated. At temperatures above 450° and pressures near to 26 atmos., hydrogen in presence of iron reduces the decomposition products of aldehyde, forming saturated hydrocarbons, but neither carbon dioxide up to 50 nor nitrogen up to 78 atmos. Pressure has any influence on the course of the catalytic decomposition of alcohol. When the experiments were performed in iron tubes, the residual liquid contained undecomposed alcohol, aldehyde, and higher unsaturated hydrocarbons, formed by the polymerisation of ethylene. Ethylene very readily polymerises when heated in a sealed tube at 400 - 450° in the presence of iron or copper, but at very high temperatures much ethane, methane, and hydrogen are also Obtained as by-products. In the presence of an excess of hydrogen more gaseous hydrocarbons, chiefly methane, are obtained. The reaction always tends to an equilibrium, after which further heating no longer produces any change in pressure' or in the proportion of the substances formed. In the presence of reduced nickel as catalyst, ethane and methane are produced. Time and pressure curves are given for the polymerisation of ethylene at various temperatures, from which it is observed that (dp/dt) max, varies considerably between 400° and Z. K.

Book Description
Excerpt from Journal of the Chemical Society, 1905, Vol. 88 of 1: Abstracts of Papers on Organic Chemistry From the foregoing summary of results, it becomes evident that a far-reaching series of changes will soon be needed in our system of atomic weights. A change in chlorine or nitrogen implies many other changes in the table, and if the accepted value for silver Should be modified the alterations would be most sweeping. The atomic weights of silver, chlorine, and bromine enter into the calculation of nearly all other atomic weights, and form, so to speak, the platform upon which the entire structure stands. The changes, however, which are suggested at present, are not final. Work is in progress in several laboratories which may confirm or modify many of the accepted values, and until that work is finished, at least so far as the fundamental data are concerned, it is wisest for us to suspend judgment and await developments. Were we to recon struct the table of atomic weights on the basis of the evidence nowbefore us, we should do it imperfectly, and a new revision would be demanded next year or the year after. Confusion would inevitably follow. Fortunately, the matter is not urgent, for the corrections which now seem desirable are not large, and the existing figures are accurate enough for all ordinary purposes. We therefore recommend that the table for 1905 be continued in use without change during 1906, even although some modifications are theoretically desirable. A year hence we shall be in a better position for a critical adjustment of the data, and no harm can follow from the delay. In accordance with the expressed wish of a majority of the larger committee, we also recommend that the table based upon the oxygen Standard be made official. So far as this committee is concerned, the private opinions of its members will be subordinated to the desires of the majority, and the table referred to hydrogen will no longer appear as a part of its report. For the present, a few suggestions may not be unacceptable, which follow from an examination of the lecture by Guye. Rayleigh, Leduc, Guye, Gray, and others, from their studies of nitrogen and its oxides, have accumulated a mass of strong evidence in favour of a lower value for nitrogen. The data furnished by Stas, on the other hand, point to the higher value which has heretofore been generally adopted. Can we abandon the one in favour of the other, and accept the new figure without reserve? About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
