1933 53-54 1465) have further described a method for the determination of benzene vapour in air based on the conversion of benzene into m-dinitrobenzene by the action of a mixture of fuming nitric and cocentrated sulphuric acids at a low temperature and by measuring the intensity of colour developed by the `m-dinitrobenzene' in alcoholic and alkaline solution with the reducing sugar laevulos [...] It is therefore evident that the formation of the tricyclic ring is conditioned by the atomic volume of the group R. In other words the greater the atomic volume of the group R the more will be the tendency of the cyclobutane ring to pass into the tricyclic ring. [...] It was expected that the compound (VI) by reason of the presence of two active methylene groups would react with two molecules of aldehyde; but it is however interesting to note that it reacts actually with one molecule of aldehyde to yield the bridged compound (VII) the constitution of which is confirmed by the fact that the aldehyde compound is insoluble in alkali. [...] The explanation that immediately suggested itself to us was that of the formation of chains of acetone molecules between the ions due to the alignment of acetone molecules under the influence of their dipole moments. [...] They would be broken during the conductivity determinations unless they were Able to withstand the potential gradients employed since the relative motion of the two ions at the ends of a chain is likely to be much more than twice the length of the chain (compare the figures in the last two columns of Table V).
