摘要

•We designed dual-end-functionalized tin (Sn)-phyllosilicate with both SO3H/SO4H and NH2 functionalities.•The optimal conditions for oleic acid conversion were determined to be 80°C temperature, 4h reaction time, 2.0% Sn-phyllosilicate loading and oleic acid:MeOH=1:1 weight ratio.•Resultant oleic acid-methyl-ester production efficiencies (%) led to ∼90%.•Catalytic activity of Sn-phyllosilicate (MTES:APTS=1.0:0.11, v/v) was maintained after recycling runs.
