Preyssler catalyst,[NaP5W30O110](14-) : A green, efficient and reusable catalyst for esterification of salicylic acid with aliphatic and benzylic alcohols

摘要

A series of eco-friendly solid acid catalysts, including H-14[NaP5W30O110], H-14-P5Mo, H-14[NaP5W29MoO110], H-14-P5Mo, and silica supported H-14[NaP5W30O110], H-14-P-5/SiO2 have been used as catalysts for esterification of salicylic acid with aliphatic alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, t-butanol, 1-pentanol, and 2-pentanol) and benzylic alcohols (benzyl, 2-methylbenzyl, 2-chlorobenzyl, 4-bromobenzyl, 3-nitrobenzyl, and 4-methoxy benzyl) alcohol.
