โœฆ Synopsis

A simple experimental technique has been developed tor evaluating the steady state heat transfer coefficient of spherical mechanically stirred continuous tank reactors tbr gas phase reactions.

Results of heat transfer experiments have been used to establish a Nusseh-type correlation, the Reynolds number being based on stirrer speed and diameter. By adjusting stirrer speed and gas composition the Reynolds number has been varied in the range 2000--60,000 and the Prandtl number has been varied in the range 0.46--0.80.

The correlation obtained, Nu = 0.39 ReO.57prl/3, compares well with those available in recent literature for liquid phase CSTR.

This calculation introduces a promising way to catalyze gas-phase S N 2 reactions at a unimolecular level by using an excess electron (EE) as an ''electron solvent''. The EE participation leads to very favorable energetics for the reaction, by neutralizing the created positive charge as the reaction
