Xia, Wen published the artcileA recyclable cucurbit[6]uril-supported silicotungstic acid catalyst used in the esterification reaction, Application of Propyl 3,4,5-trihydroxybenzoate, the publication is Inorganica Chimica Acta (2021), 120418, database is CAplus.
The esterification reaction used to prepare Bu paraben (BP) and Pr gallate (PG) catalyzed using a cucurbit[6]uril-supported Keggin-type silicotungstic acid (Q[6]-STA) catalyst has been investigated. The Q[6]-STA catalyst has been characterized using FTIR spectroscopy, XRD, SEM, EDS, thermal anal., and surface area studies. Q[6]-STA was easy to prepare in high yield and exhibited some advantageous properties, such as high catalytic activity and its convenient recovery. Moreover, a reusability study showed that the Q[6]-STA catalyst was stable and active.
