p-Toluenesulfonic acid - Wikipedia
TsOH may be converted to p-toluenesulfonic anhydride by heating with phosphorus pentoxide. [12] When heated with acid and water, TsOH undergoes hydrolysis to toluene: CH 3 C 6 H 4 SO 3 H + H 2 O → C 6 H 5 CH 3 + H 2 SO 4. This reaction is general for aryl sulfonic acids. [13] [14]

2015年4月16日 · If you see a tertiary or secondary alcohol with H 2 SO 4, TsOH, or H 3 PO 4 (and especially if you see “heat”) think: carbocation formation followed by elimination reaction (E1). And if you see that a more stable carbocation could be formed through migration of an adjacent H or alkyl group, expect that to happen.
