On the solubility of solids in gases; A lecture demonstration for supercritical fluids

An effective and inexpensive method is described for projecting an image of a high-pressure silica capillary cell so as to be viewed by a large audience. The apparatus is based on an overhead projector deployed in a highly unusual manner. Its use is illustrated by the solubility of guaiazulene in supercritical ethane. The technique has potential applications as a view cell in research laboratories.

The solubility of solids in gases

That gases can dissolve solids has been known since the work of Hannay in 1879-1881. The historical and theoretical aspects of this phenomenon are discussed, and the literature of the subject is summarized and reviewed. Some previously unpublished results from the Geophysical Laboratory on the solubility of UO 2 , Al 2 O 3 , NiO, Nb 2 O 5 , Ta 2 O 5 , BeO and GeO 2 at 500 degrees C, 1,000 bars steam pressure, are included.

I. On the solubility of solids in gases

The research which we now have the honour of submitting to the Royal Society, and of which a preliminary notice was published in the Society's Proceedings, was instituted with the view of throwing some further light upon what Dr. Andrews calls the "critical state" of matter. In his famous Bakerian lecture, after a very careful discussion of the question, Dr. Andrews says : "Carbonic acid at 35·5° C., and under a pressure of 108 atmospheres, stands nearly midway between the gas and the liquid, and we have no valid grounds for assigning it to the one form of matter any more than to the other.

II. On the artificial formation of the diamond

While pursuing my researches into the solubility of solids in gases. I noticed that many bodies, such as silica, alumina, and oxide of zinc, which are insoluble in water at ordinary temperatures, dissolve to a very considerable extent when treated with water-gas at a very high pressure. It occurred to me that a solvent might be found for carbon; and as gaseous solution nearly always yields crystalline solid on withdrawing the solvent or lowering its solvent power, it seemed probable that the carbon might be deposited in the crystalline state. After a large number of experiments, it was found that ordinary carbon, such as charcoal, lampblack, or graphite, were not affected by the most probable solvents I could think of, chemical action taking the place of solution. A curious reaction, however, was noticed, which seemed likely to yield carbon in the nascent state, and so allow of its being easily dissolved. When a gas containing carbon and hydrogen is heated under pressure in presence of certain metals its hydrogen is attracted by the metal, and its carbon left free. This, as Professor Stokes has suggested to me, may be explained by the discovery of Professors Liveing and Dewar, that hydrogen has at very high temperatures a very strong affinity for certain metals, notably magnesium, forming extremely stable compounds therewith.

The Solubility of Gases in Solids

MESSRS. HANNAY and Hogarth recently communicated to the Royal Society an important paper on the Solubility of Solids in Gases. The subject, an outline of which was given to our readers in an abstract of a preliminary paper by the same authors a few weeks ago, has attracted the more notice since it led Mr. Hannay to the research upon the artificial production of crystallised carbon, which is associated with his name.

Artificial Production of Diamonds

GLASGOW seems determined to have the honour of producing the diamond artificially. In spite of Mr. Mactear's recent failure, Mr. J. B. Hannay, whose paper on the solubility of solids in gases we published not long ago, has been utilising the method indicated in that paper in experiments on the artificial production of the diamond. Mr. Hannay reads a paper on the subject at the Royal Society to-night, and any remarks on his work we shall postpone for the present. Meantime from the letters and articles that have appeared in the papers, we may form some idea of what has been done. Prof. Story Maskelyne, writing to the Times, says:—

VI. On the solubility of solids in gases

This investigation was undertaken in the hope that, by an examination of the conditions of liquid matter up to the “critical” point, sufficient knowledge might be gained to enable us to determine under what particular conditions liquids are dynamically comparable, in order that the microrheometrical method (which the Royal Society has done one of us the honour of publishing in the “Philosophical Transactions”) might be applied to determine their molecular mass and energy relations. It seemed that as the laws relating to gases and liquids merge at what was called by Baron Cagniard de la Tour “l’état particulier,” and by Dr. Andrews the “ critical point,” an examination of matter up to the limit of the liquid state would belikely to yield us much information. The time we have to devote to scientific work being very limited, we found that it was quite impossible to make much advance by using the apparatus devised by Dr. Andrews, as the time required to change from one liquid to another was more than we had at our disposal.

THIS investigation was undertaken in the hope that, by an examination of the conditions of liquid matter up to the “critical” point, sufficient knowledge might be gained to enable us to determine under what particular conditions liquids are dynamically comparable, in order that the microrheometrical method2 (which the Royal Society has done one of us the honour of publishing in the Philosophical Transactions) might be applied to determine their molecular mass and energy relations. It seemed that as the laws relating to gases and liquids merge at what was called by Baron Cagniard de la Tour3 “I'état particulier,” and by Dr. Andrews4 the “critical point,” an examination of matter up to the limit of the liquid state would be likely to yield us much information. The time we have to devote to scientific work being very limited, we found that it was quite impossible to make much advance by using the apparatus devised by Dr. Andrews, as the time required to change from one liquid to another was more than we had at our disposal. We therefore devised a new apparatus, which will be described in a more lengthy communication, but which, we may state, can be opened, the liquid changed, and again closed for a new experiment, in about one minute.
