2,2-Dimethylsuccinic anhydride Use and Manufacturing
This example describes experiments in which isobutylene oxide or α-butylene oxide were reacted with carbon monoxide in neat epoxide or toluene in the presence of two different catalysts. Table 5 reports the catalyst loading (expressed as molar ratio of epoxide to catalyst) and anhydride yield for each catalyst/solvent combination.[0081] A suspension of 219 g (1.5 mol) of 2, 2-dimethylsuccinic acid in 220 mL of toluene is heated to 130
