Summary

This JavaScript model integrates the rate equations of the mechanism proposed by Pearson et al for the reaction of formation of cholesterylisothiuronium tosylate from thiourea and cholesteryl tosylate. The model details, activities and references are accessible by the PDF button. The mouse over a label displays a tool tip. The default concentrations at the top fields are the initial concentrations at time=0.0. As the program runs the concentrations are successively updated. The colors of the concentration labels correspond to the colors of the respective plot lines. Note that while the concentrations in the top fields are in mole/liter, they are plotted in milimole/liter. Clicking on a point of any curve displays the respective coordinates.

The t/m field displays the time in minutes of Pearson's reaction. The 1st bottom button displays the results of the run in steps of 20 min by default. However, it can be changed through the spd field as explained in the activities. The 2nd button runs the program continuously until it pauses at 550 min (the time followed by Pearson). The 3rd button resets the program to the default values. After reseting, the program can be executed again.
