The Similar Chemical section contains one field – the Similar Chemical field.
This field stores the name of a chemical having a molecular structure similar to that of the current chemical. Some estimation techniques use the properties of the similar chemical as a starting point for the property estimates of the current chemical. The values are modified depending upon the differences in molecular structures. For example, if the current chemical was propanol we might specify ethanol as a similar chemical. To estimate propanol’s boiling point, some estimation techniques would first find ethanol's boiling point and then adjust the value to account for propanol's extra methylene group.
Several estimation techniques use a similar hydrocarbon as the basis for initial property values. For example, to estimate the properties of 1-hexanol, such an estimation technique would start with the physical property value for n-hexane and then modify this value to adjust for the differences between the two structures.
Clicking the left mouse button on the section's edit control activates the Similar Chemical edit dialog. The dialog enables you to enter the name of a similar chemical, a reference, and comments.
The Similar Chemical edit dialog has many of the same controls as the Text-Reference dialog. Documentation on the Text-Reference dialog can be found here.
|Find Button: pressing the dialog's Find button activates the Select Chemical dialog. This dialog lists all the chemicals in the current document. The dialog enables you to list chemicals by name or synonym. See the documentation on the All Entities Dialog for details.
The commands menus for text entry controls, e.g., the name control, the reference control and the comments control, have commands for copying, pasting, inserting symbols, and changing case. The commands menu is displayed by clicking the right mouse button on a text entry control.
Clicking the right mouse button within a field's datum control activates the field's datum commands menu.
Documentation on each of the menu commands can be found here.
