Miniemulsion enzymatic reactions
Webefforts have been put in using water as a (green) reaction medium for enzyme transformations [19-20]. Miniemulsions are heterophase systems consisting of uniform, … Webvia emulsion and miniemulsion polymerizations are reported. Reactions in which the vinyl acetate was introduced in both batch and semibatch modes are carried out. (Ethylene introduction is always in a semibatch model since the polymerization is carried out under a constant pressure of ethylene in the reactor headspace.) The results are compared ...
