Abstract:

A novel solid sulfonic acid was prepared from coconut shell via carbonization and sulfonation and used as catalyst for the condensation of aldehydes and resorcinol, calix[4]resorcinarenes were prepared rapidly in good yield (49%-95%). The structures of the target compounds were confirmed by IR1H NMR and MS.

Key words: coconut char sulfonation, solid-state catalyst, grinding method, aldehyde, resorcinol
