High proton content polytungstoboronic acid H7BW11TiO40 (abbreviated as H7BW11Ti) had been prepared through titanium mono-substituted of H5BW12O40, which was evaluated in esterification of palmitic acid with methanol. H7BW11Ti could promote esterification reaction with almost 100% conversion of 417 mol/mol h TOF within very short time of 1 h at methanol/acid ratio of 25:1 under reaction temperature...
