CRC Handbook of Chemistry and Physics (Web版)
The CRC Handbook of Chemistry and Physics has been one of the most important data reference books used by scientists worldwide for over fifty years.

DETHERM (热物性数据库)
The DETHERM database provides thermophysical property data for about 21,000 pure compounds and 101,000 mixtures. These data are indispensible for the design of apparatus and chemical production facilities. DETHERM contains Literature values, together with bibliographical information, descriptors and abstracts. At the time 4.2 million data sets are stored. Convince yourself from the coverage and content of our database using the Online System.

DIPPR (物性数据)
The Design Institute for Physical Property Data (DIPPR) of the American Institute of Chemical Engineers has become the premier cooperative physical property data effort in the United States to satisfy process engineering needs. Celebrating its twentieth anniversary in November 1998, DIPPR has been active longer than any other Sponsored Research group of AIChE.

Elemental Data Index (元素的物理数据)
The Elemental Data Index provides access to the holdings of NIST Physics Laboratory online data organized by element.

电解质溶液数据库(ELYS :- Electrolyte Solutions Database)
ELYS provides a wealth of information concerning thermodynamic and transport property data, such as density, viscosity, diffusion, coefficients, etc. Currently contains about 11,000 entries.
