The ChemExper chemical directory (www.chemexper.com) provides a substructure searchable database claimed to contain 60,000 chemicals with melting or boiling points, where available. No toxicity or environmental property data are given. 

More than 6000 compounds with a boiling point values at 760mmHg or latm have been collected by ACDlabs (http //www.acdlabs.com/products/ phys chem lab/bp/). The same number of compounds, with BP measured at different pressures are available in the PHYSPROP database [14], CHEM-EXPER (http //www.chemexper.com) has experimental BP data for more than 7500 compounds. The experimental BP data are also provided by ChemFinder (http //www.chemfinder.com) and ChemIDplus (http //chem.sis.nlm.nih.gov/...

The ChemExper Chemical Directory (http //www.chemex-per.com/) is also listed below as a resource for searching available chemicals from various supplier catalogs. Links are provided to the supplier s web site and to MSDS. Only the basic properties are directly provided density, m.p., b.p., and flash point. However, links to the full text of the MSDS will usually provide some additional properties. 

The site http //www.chemexper.com also allows access to ExpereacE WEB, a laboratory management program that helps to keep stock control, order products, add reactions (electronic laboratory journal), export all the information to... 

ChemExper ChemExper is a company that joins together the areas of chemistry, computer science, and telecoimnunication. The ChemExper Chemical Directory is a free service that allows finding a chemical by its molecular formula, lUPAC name, common name, CAS niunber, catalog number, substracture or physical characteristics, as well as chemical suppliers. This database contains currently more than 500,000 chemicals, 16,000 material safety data sheet (MSDS), 10,000 infrared (IR) spectra, and more than 500 chemical suppliers. 

The ANN model was developed with the five variables available in the input layer, corresponding to the (i) mole fraction of ethanol (Xj), (ii) mole fraction of water (in) mole fraction of ionic liquid (jJj), (iv) molecular weight of pure ionic liquid MJ, and (v) density of pure ionic liquid (p). As mentioned earlier, these variables were compiled from the literature [2,3,7,8,26], and the molecular weights were compiled from ChemExper, ChemicalBook, and chemBlink websites [28-30],...
