the half-life of BAL in the presence of the investigated solvents, but without formation of distinct solvent phases is 17.3 h, 5.6 h and 3.2 h for saturation with methyl-tert-butylether, 2-octanone, and toluene, respectively, in non-reactive monophasic media. With MTBE, 2-octanone, and toluene, very similar half-lives of 1.5 h, 1.4 h and 2.0 h are found for unmodified BAL under process conditions in reactive biphasic media. The initial activity of BAL decreases to approximately 60%, when methoxy-poly(ethylene) glycol (mPEG)750 is attached, and to 70%, when a longer-chain mPEG2000 is used. Overall, the modification with mPEG leads to good stabilization of BAL under non-reactive conditions. The strongest effect is achieved against toluene, where the stability of mPEG2000-BAL surpasses the stability of unmodified BAL by factor 18
