, respectively, were derived from the standard molar energies of combustion, in oxygen, to yield CO2(g) and H2O(l), at T = 298.15 K, measured by static bomb combustion calorimetry. The Knudsen mass-loss effusion technique was used to measure
the dependence of the vapour pressure of the solid isomers of hydroxymethylphenol with the temperature, from which the standard
molar enthalpies of sublimation were derived using the Clausius–Clapeyron equation. The results were as follows:
, for 2-, 3- and 4-hydroxymethylphenol, respectively. From these values, the standard molar enthalpies of formation of the
title compounds in their gaseous phases, at T = 298.15 K, were derived and interpreted in terms of molecular structure. Moreover, using estimated values for the heat capacity
differences between the gas and the crystal phases, the standard (p° = 0.1 MPa) molar enthalpies, entropies and Gibbs energies of sublimation, at T = 298.15 K, were derived for the three hydroxymethylphenols.

During the last few
decades, there has been a rapid increase in research on as well as engineering
in calorimetric systems, which become of wide use in modern material science.
Sensor and chip technologies, instrumental and computerized systems of control
and measurement have developed rapidly and the thermal properties of new materials,
in particular thermokinetic effects and thermal stability has moved increasingly
into the centre of interest. However, today’s knowledge in the calorimetry
is distributed among vast number of highly specialized publications. Therefore
a collection and summarization of this knowledge is certainly most welcome
and thus this book furnishes scientists and engineers with a publication containing
The author has extensive experience and is probably one
of the most knowledgeable scientists in the field of experimental and theoretical
study related to thermochemistry and calorimetry, and has published intensively
in the past on the subject of the book. Zielenkiewicz’s new book passes
in review the applications of a wide range of calorimetric techniques, including
modified versions and combinations thereof.
The book contains 11 chapters, covering a wide field
of topics related to thermophysical measurements, in particular
determination of heat effects involved in various physical, chemical and biological
processes, which is essential in molecular and supramolecular thermochemistry,
in thermodynamic study of molecular interactions in liquid solutions, of the
nature of bonds in alloys and polymers and in living organisms. Another field
of interest is the industrial applications and biocalorimetric research on
1 provides an excellent outline of the history of calorimetry development.
The first part of
Chapter 2 presents a short overview on heat transfer. In the second part of
the chapter the static-dynamic method for determination of heat effects in
calorimeters are presented, restricted to fundamental knowledge alone. This
chapter seems to be the most interesting one for scientists and practitioners
using or developing thermal analysis devices. In Chapter 3, the analysis of
heat effects courses occurring in the calorimeters as well as dynamic properties
of calorimeters are discussed. Although Chapters 2 and 3 are written at a
rather high physical and mathematical level, they contain only the absolutely
4 gives an almost state-of-the-art overview of classification of calorimeters
and methods for determination of heat effects. A short review of calibration
and test reactions is also included. In Chapter 5, the adiabatic calorimeters
are outlined. Chapter 6 is a guide for isoperibol, batch and nonadiabatic–nonisothermal
calorimeters. Chapter 7 is a short review of calorimetric and indirect methods
of determination of enthalpy of sublimation. It is an important chapter, but
offers only a few points of contact with the rest of the book. Chapter 8 is
devoted to detailed discussion of the batch, displacement and flow calorimeters.
Chapter 9 discusses the conduction calorimeters, their possibilities and limitations.
Sections on thermokinetic studies and determination of kinetic parameters
are included. The presentation is very clear and straightforward, even of
the fairly complicated theoretical derivations. Chapter 10 reports nonisothermal–nonadiabatic
scanning devices, systematically analyses their applications to thermal analysis
and gives a summary of the principles of DSC. Chapter 11 reviews briefly the
pressure scanning calorimeters. The paragraph, although very short, is of
special interest for the transistometry.
Some of the chapters are excellent reviews of the
literature while others are largely from the authors valuable own work. The
necessary fundamental knowledge seems to be included almost completely even
the special literature which can be found in the extensive list of references.
The chapters of the book are correct presentations of the types of apparatus
available, the methods of measurements and theories and applications associated
with that part of the discipline under consideration.
The book provides the reader with information about
the development of calorimetry and its present day applications. Besides generally
discussing the calorimetric techniques and the possibilities of their applications
the book also elaborates the measurement of a wide variety of physico-chemical
data (enthalpy of solution, dilution, mixing, sublimation, fusion, evaporation,
adsorption, reaction, transformations, decomposition, polymerization; heat
capacity, kinetic parameters, etc). In addition to detailed presentation of
these measurements the book also describes special applications such as e.g.,
for studying liquid-crystal substances, biopolymers and photo-thermoelastic-acoustic
phenomena. The author also pays attention to techniques that are seldom found
in other books.
interested reader will profit by reading it and is guided through the essentials
of this special, though important field which will rarely be found in normal
books on thermal analysis. Therefore this book is a stop-gap work and exposes
both the experts and the scientists, who are not familiar with calorimetric
methods, to this knowledge. The text is well-written and readable with only
few errors. Symbols and definitions are consistent between chapters, but not
always follow the IUPAC recommendations. The nomenclature is correct. The
figures in the book are helpful and the figure quality is variable but appropriate
in spite of the various origins. However, the book lacks for an explanatory
list of symbols and subject index.
In summary, this book represents an excellent discussion
of the theory and practice of calorimetry, will help to further an understanding
of the various facets of the technique and should promote its application
to new problems. The book contains much useful information, serves a useful
purpose as a reference publication. It is wholeheartedly recommended reading
for both the experienced scientists and the newcomers. Hopefully, the book
under review will used as a frequently consulted work by everybody involved
in the use of calorimeters.
