Cheméo is first a chemical and physical property search engine. Also at the moment only a limited number of components are available for search, it has been built to handle Terabytes of data with good performances. You can expect the index to grow a lot with the time.
The search syntax is simple and easy to remember and an advanced search page is available to build your query easily.
Free search, a bit like searching with Google:
nitrogen acid: all the components with nitrogen and acid in the name.alcohol C7H6Cl2O: all the components with alcohol in the name and C7H6Cl2O in the formula.74-82-8: Components with the CAS 74-82-8. If only one component is found, you are directly sent to the detailed view of the component.Property search, to find components by property:
tb:300;400: all the components with a boiling point between 300 and 400K.tb:;400 tc:500;: all the components with a boiling point below 400K and a critical temperature above 500K.hf:;: all the components with at least one experimental data point for the enthalpy of formation at standard conditions.You can get the list of all the property operators from the advanced search query builder.
Smart search results, as you have noticed, if you search for a property, you get a column with the property value or range for each component. You can add more properties to the list:
tb:300;400 show:tc: all the components with a boiling point between 300 and 400K and show the critical temperature in the search results.tc:500; show:hf: all the components with a critical temperature above 500K and show the enthalpy of formation.Again, you can get the list of all the property operators from the advanced search query builder.
With a large database, Cheméo provides the raw data to build QSPR/QSAR models. Learn more about the regression tools.
For the molecule with a Joback ond Reid description, it is possible to predict up to 11 properties with the Joback and Reid property prediction method for chemical molecules.
If you like technical stuff, you learn more about the technology and tools used to run Cheméo and a description of our private OpenVZ cloud.
