THE COMPATIBILITY OF A POLYMERIC CATALYST SUBSTRATE SOLVENT AND REACTION-RATE .3.

In the presence of solvent, the catalytic rate in a polymeric metal co mplex catalyst (2)-substrate (1)-solvent (0) system is related to the solubility parameters (delta(i)) of the three components. According to thermodynamic and kinetic theories, an approximate relationship betwe en the reaction rate and solubility parameters has been deduced as fol lows: [GRAPHICS] where phi2 is volume fraction of polymeric catalyst a nd V1 is mole volume of substrate. For a given polymeric catalyst and a given substrate, the effect of different solvents on the rate could be simplified as r = A/1 + D . exp(-B (delta0 - delta2)2) where A, B, and D are constants. From this formula it can be seen that the rate is a function of solubility parameter of solvent in the form of the reci procal of a normal distribution. This result has been supported by exp eriment.
