“…Plank (21) further states, "In connection with particularly accelerated freezing, changes in the distribution of internal water appear smaller than in produce frozen at a slow speed." Thus was developed the theory of speed of freezing which indicates the desirability of freezing rapidly in line with the findings of Tammann (26) in 1898 who stated that the number of crystallization centers developing in undercooled fluids depends directly upon the rapidity with which the temperature of the fluid is lowered; and with Fortuyn (9) in 1915, who stated that quick-freezing does not cause any rupture of the sarcolemma as does slow-freezing.…”

The functional form developed in Stringari Stringari J. Chem. Eng. Data20216611571171 has been applied for obtaining a Gibbs free energy equation of state (EoS) for phase I of solid benzene. The EoS has a validity range from 15 K up to the temperature and pressure of the solid II–solid I–liquid triple point, that is, 488.3 K and 1164.6 MPa. The EoS parameters have been regressed on literature data of molar volume, isothermal compressibility, thermal expansion, and isobaric and isochoric heat capacities. The average absolute deviation between the EoS and the primary data is 6.8% for isothermal compressibility, 5.5% for isobaric thermal expansion, 0.9% for molar volume, 2.7% for isobaric heat capacity, and 4.9% for isochoric heat capacity. The EoS maintains a physically correct behavior in the whole range of temperature and pressure of existence of phase I of solid benzene. The developed EoS for solid benzene has been coupled with the reference equation of state for the fluid phases developed by Thol Thol High Temp.-High Press2012418197 for calculating the melting and sublimation curves. Predictions of sublimation pressures are in excellent agreement with the recommended values of Ružička Ružička J. Chem. Thermodynamics2014684047 and those of melting temperatures matches very well the values obtained from the auxiliary melting equation in the validity limits of the EoS of Thol Thol High Temp.-High Press2012418197.

“…The best object for studying this influence is dehydrated chabasite, as I have shown (93). Tammann has called attention to the fact that chabasite belongs to a class of minerals which remain transparent after dehydration (94). Brill has established that the lattice of chabasite is not changed by dehydration ; the pores which are produced by dehydration are therefore of quite extraordinary regularity.…”

The process of catalytic hydrogenation of organic compounds is of great interest, not only industrially but also scientifically.It comprises the hydrogenation of fatty substances, the hydrogenation of carboxides with formation of methanol, and a host of other important chemical processes. I n order to master these reactions the most important step is to understand their mechanism.I n hydrogenating fatty oils one or more double bonds between carbon atoms are converted into single bonds ; in hydrogenating carboxides one or more double bonds between carbon and oxygen atoms are reduced. This seems to be a close analogy; nevertheless the mechanism of the two processes is probably quite different, as we shall see later.We consider first the mechanism of the hydrogenation of multiple carbon bonds. For a long time I have adhered to the theory (1) that catalytic hydrogenation of multiple carbon bonds belongs to the great class of catalytic reactions that are produced by ions. I am glad now to have the opportunity of surveying the facts which seem to me to prove that ionic catalysis is involved in this type of hydrogenation.But first, what is ionic catalysis? Ostwald (2) and Arrhenius (3) were the first to find that ions 1 This is the first of a series of three articles. 11, The Dissociation of Carbon Bonds, is scheduled for publication in
