AccessEngineering includes many science and engineering reference materials, including a wide range of property data resources, including Lange's Handbook of Chemistry, and Perry's Chemical Engineers' Handbook.
Knovel provides access to reference materials in the fields of engineering and applied sciences. Find chemical and physical property data of all types, including thermodynamic data from the DIPPR project.
This catalog can be searched by common name, CAS number, or catalog number. The entries on each substance include a large amount of physical data and properties. Each compound is listed in all of its commonly used forms with corresponding properties.
This resource uses the Peng-Robinson equation of state to calculate the thermodynamic properties of fluids. The thermodynamic models within CANARY can predict fluid compositions and properties following an adiabatic flash. Given the storage conditions (temperature and pressure) and fluid composition (up to 10 components) of the fluid, CANARY may predict the compositions of the gas, aerosol, and/or liquid phases of the fluid following a release (flash).
This website allows you to search for information on a certain chemical, element, gas, etc. based on its chemical name, CAS number, molecular formula or weight. The results include the component's structure, formula, density, etc., as well as MSDS and related information.
PubChem provides information on the biological activities of small molecules. PubChem includes substance information, compound structures, and BioActivity data in three primary databases, Pcsubstance, Pccompound, and PCBioAssay, respectively. The Substance/Compound database, where possible, provides links to BioAssay description, literature, references, and assay data points. The BioAssay database also includes links back to the Substance/Compound database.
