Pure Component Properties in a Mixture Data Bank

Some pure component properties are stored in mixture data banks.

In case of the VLE data bank for vapour-liquid equilibria some pure component vapour pressure data sets are stored from the same publication from which also mixture VLE data have been entered. The intention is to keep these data together. This is a service for VLE data bank customers who haven't licensed the pure component properties data bank.

In case of the data banks derived from the "Extended data bank" some pure component data are available there mostly because specific problems to store the data in the normal pure component properties data bank (PCP). A problem might be a poor component specification, obscure old-fashioned units which cannot be converted into SI, major and multiple impurities, and more such reasons.
