Effects of Ultrasound Time, Power, and Temperature From Figure 1 D, the yield of proanthocyanidins showed a trend of increasing and then decreasing with increasing ultrasound time, and when the ultrasound time exceeded 30 min, the yield of proanthocyanidins instead began to decrease, which was attributed to the fact that excessive prolongation of the ultrasound time triggered the oxidation or degradation of proanthocyanidins [ 19 ].
In the free acidity ( Figure 10 A) and acetyl content data ( Figure 10 B), a clear trend can be observed: in the sample stored without any inhibitors, the deacetylation process was dramatically pushed until a lowering of the overall degree of substitution of the polymer (from cellulose diacetate to cellulose monoacetate [ 3 , 31 ]); a similar trend was also evident for RMPF stored in the presence of pure PVF and WP, for which the deacetylation was only slowed down.
Taking the partial significance descriptors discussed above as an example, we suggest adjusting the large ring counts to decrease the molecule’s hydrophobic surface area and optimize ring connectivity in order to control the number of five-membered aromatic rings to decrease the potential for reactive metabolite formation and reduce the likelihood of generating toxic intermediates.

One immediate and highly significant implication of this finding is that it would be advisable to migrate the CO 2 C(CH 3 ) 3 group in the first rearrangement, followed by either CO 2 CH 3 or CO 2 C 2 H 5 in the second rearrangement, if it is desired to prepare an N -methyl or N -ethyl saccharin corresponding to 18 , Scheme 5 .
