Toluene was sulfonated by gaseous sulfur trioxide to prepare p-toluenesulfonic acid. The effects of reaction temperature and toluene conversion on the isomer selectivities and the dynamic viscosity of the reaction mixture in a well-stirred tubular glass reactor of 4 cm diameter and 16 cm height were
## Abstract The reactions of the alkenoic acid derivatives 1aβ19a with sulfur trioxide were studied in the temperature range β60 to 25Β°C using dichloromethane as solvent and 1.5 equiv. of dioxane as reactivity moderator. The alkenoic acids 13a and 14a, having a β(CH~2~)~4~β and β(CH~2~)~7~β linkage
