Abstract

Utilizing the biphasic system water/CO2 as a reaction and extraction medium is of rising importance, because of its advantages as a green solvent combination. The problem of predictable pH control in the aqueous phase has to be addressed in view of optimized reaction conditions. The control is possible up to a pH of approximately 6 by means of buffer salts, and the resulting pH can be predicted by an algebraic equation.
