HSC Chemistry® for Windows
Chemical Reaction and Equilibrium Software
HSC Chemistry is the world's favorite thermochemical
software. HSC is designed for various kinds of chemical reactions and
equilibria calculations. The current version contains twelve calculation
modules displayed as twelve options in the HSC main menu:
The name of the program is based on the feature that all
twelve calculation options automatically utilize the same extensive
thermochemical database which contains enthalpy (H), entropy (S) and
heat capacity (C) data for more than 15000 chemical compounds. This
database is equivalent to more than fifteen thick data books.
The objective of HSC is to make conventional
thermodynamic calculations fast and easy to carry out using personal
computers. Therefore HSC has a wide range of application possibilities
in scientific education, industry and research. Thermochemical
calculations are useful, for example, when developing new chemical
processes and improving old ones. HSC Chemistry is also a useful tool
for universities and schools in chemical practicals and studies.
Traditionally, thermodynamic calculations based on
experimental or assessed data have utilized stability functions in
various thermodynamic data books and papers in scientific journals. The
difficult searching stage and complicated calculations, as well as
inconsistencies arising from different selections of standard and
reference states, have made this calculation procedure quite
time-consuming.
HSC Chemistry offers powerful calculation methods for
studying the effects of different variables on the chemical system at
equilibrium. For example, if the user gives the raw materials, amounts
and other conditions of almost any chemical process, the program will
give the amounts of the product as a result. HSC also makes heat and
material balance calculations of different processes much more easily
than any manual method. The Eh-pH-diagrams option of HSC also offers a
very fast way of studying the dissolution and corrosion behavior of
different materials.
Of course, HSC does not solve all chemical problems,
because it does not take into account the kinetics (rates) of the
chemical reactions and non-ideality of solutions. However, in many cases
it is a very inexpensive and useful tool which helps to find the optimum
reaction conditions and yields for experimental investigations without
expensive trial-and-error chemistry.
