The process comprises the following steps: a) bringing the liquid mixture into contact with a non-functionalized organic polymer which has pores having an average pore diameter of less than 50 Ä, the pore diameter being determined according to DIN ISO 66134; b) optionally separating the non-functionalized organic polymer.
