Multiple Master/Detail data views

Multiple Master/Detail data views in the ILThermo web pages are used to present the related data of ionic liquids in a series of tables. A master table is the upper table in a series, while a detail table is the table attached to the upper table. When an entry in the master table is selected, all available data pertinent to this entry will be populated in the sequential detail tables. In this series, the top table is a master table and the bottom table is a detail table, while all other tables in the middle are both master/detail tables. The selection can be done for a master table at any level of the series based on your particular needs and interest.
With this technology, ILThermo enables users to efficiently and easily retrieve comprehensive ionic liquid data in one data page by effortlessly navigating through a series of lists and tables. For example, when an ion is selected in the top table of a series, all collected ionic liquids pertinent to this ion, an index of properties related to these ionic liquids, and all data sets for these ionic liquids/properties would be displayed in the sequential table series. Within this high density data screen, it is possible to obtain a thorough view of details restricted to a particular ionic liquid, property or data set.

Chemical identifier information of ions

Select to jump to the top of the pageReturn to Top
Chemical identifier information of ions is presented in two parts: (1) the chemical identifier information on ions sorted by ionic formula. This contains the formula for cations or anions, their ionic charge, and names, as well as ionic structures. (2) The chemical identifier information on all available ionic liquids that contain the particular ion selected.

Chemical identifier information of ionic liquids

Select to jump to the top of the pageReturn to Top
Chemical identifier information of ionic liquids is presented in two parts: (1) the chemical identifier information on ionic liquids sorted by molecular formula. This contains the formula for ionic liquids, their molecular weight, name and molecular structures. (2) The chemical identifier information on the ions that constitutes the selected ionic liquid.

Binary and ternary mixture systems

Select to jump to the top of the pageReturn to Top
Binary and ternary mixture systems are selected and displayed when searching property data for multi-component systems containing ionic liquids. The majority of the mixture systems collected in ILThermo contain only one ionic liquid component, such as ethanol + 1-hexyl-3-methylimidazolium tetrafluoroborate or benzene + heptane + 1-methyl-3-octylimidazolium chloride, while few are binary or ternary ionic liquids mixtures such as 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide + 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide.

Property data

Select to jump to the top of the pageReturn to Top
Property data is organized and displayed in seven parts: ions, ionic liquids, index of properties, selection of a data set, sample purity and measurement, chemical system and their numerical values, and literature information.
- The section of ions and ionic liquids contains chemical identifier information on those ionic liquids for which experimental investigations are reported. The relationships of ions and ionic liquids are identified by, for example, ionic liquids containing the same ion and the ion pair making up an ionic liquid.
- The index of properties provides a list of properties for the selected ionic liquid with a total number of references and data points for the ionic liquids.
- The data set section includes a complete description of the selected data set. A data set in ILThermo is identified by a combination of ionic liquid, property, reference, sample and the set number, which represents some of the key information that must be identified for a concrete experimental investigation. An ionic liquid is the target compound of the measurement; a property indicates the interest of the investigator; the reference gives the source of the data; the sample distinguishes multiple investigations; and a set number is given for a group of data under different system state variables, such as temperature, pressure, or composition.
- The sample purity is described through its initial source, initial purity, and initial purification methods, followed by its final purity and purity analysis method. Measurement methods and purpose are also provided.
- The numerical value section displays the numerical values of the selected data set in a tabular format, along with information on chemical system, system constraints, and state variables. The estimated uncertainty by ILThermo is also presented along with the data results.
- Literature information contains the year of publication, authors, and the source of the report, title, abstract and keywords.

Numerical Values

Select to jump to the top of the pageReturn to Top
Numerical values of properties, variables, and constraints are those reported in the original publications (converted to SI units if necessary). Numerical values of assigned uncertainties are displayed with two significant digits.

Conversion of Temperature Units

Select to jump to the top of the pageReturn to Top
All temperatures in ILThermo are expressed in Kelvins. Temperatures reported originally in Celsius (°C) are converted to Kelvins (K) with the following relationship.

T(K) = T(°C) + 273.15

MolaLity and MolaRity

Select to jump to the top of the pageReturn to Top
The word format "MolaLity" and "MolaRity" is used in the Property Description in the data pages in order to clearly distinguish the two words.

Properties at Infinite Dilution

Select to jump to the top of the pageReturn to Top
Some properties, such as Activity Coefficient at Infinite Dilution include the concentration specification explicitly in the name. In some cases this is not practical, and a zero concentration is included explicitly in the data set conditions.
