Some commercial sulfonations and sulfations employ nearly stoichiometric quantities of reagents and yield products which can be neutralized and used directly as is, or with minor purification. These include benzene, toluene, and xylenesulfonic acids as prepared by the partial-pressure distillation method dodecylbenzene sulfonated with SO3 long-chain alcohol sulfates prepared with ClSQjH, SOs, or NHjSOiH some sulfonated aromatic amines as prepared by the baking process and products from certain sulfoalkylation or sulfite reactions (see technical section for detailed examples). In other cases, even when excess acid is present, it is neutralized with the sulfonate since sodium sulfate is desired or allowable in the final product. Examples include dodecylbenzene sulfonated with oleum and lauryl alcohol sulfated with concentrated acid. In most cases, however, separation or purification is necessary. The three most common procedures may be summarized as follows ... [Pg.362]

The equilibrium for the transesterification of isoamyl acetate by ethanol can be affected by the solvent system. This reaction was studied in SCCO2, the IL [BMIMjfPF j and the scC02-[BMIM][PF6] biphasic system at 65 °C using p-xylenesulfonic acid (p-TSA) as a catalyst [Eq. (12)] [60]. [Pg.707]

The corresponding mass spectrum of the main peak is shown in Fig. 7-55 (top) and compared to that of a respective standard (bottom). In both cases, the background signal has been subtracted. Smaller signals such as m/z 104 and m/z 186 correspond to p-xylenesulfonic acid, m/z 94 and m/z 158 to benzenesulfonic acid, which are both present as impurities. Although the application of a particle-beam interface is limited to analytes with a significant vapour pressure in the... [Pg.533]
