Abstract

Conclusions Mass transfer of reactant from bulk liquid to the catalyst surface is an important factor limiting rates of polymer-bound phasetransfer-catalyzed reactions of alkyl halides with aqueous sodium cyanide unless rapid mechanical stirring is used. In our experiments, at least 400 rpm, and preferably 1600 rpm, is required to make rate limitation by mass transfer negligible. With use of other reaction vessels and mixing methods, the conditions required ...
