A novel Brönsted–Lewis acidic heteropoly organic–inorganic salt: preparation and catalysis for rosin dimerization

A novel Brönsted–Lewis acidic heteropoly organic–inorganic salt has been prepared via the replacement of protons in neat phosphotungstic acid with both organic and metal cations. This hybrid catalyst, Sm(0.33)[TEAPS](2)PW(12)O(40), exhibited satisfactory performance in the dimerization of rosin to p...

description A novel Brönsted–Lewis acidic heteropoly organic–inorganic salt has been prepared via the replacement of protons in neat phosphotungstic acid with both organic and metal cations. This hybrid catalyst, Sm(0.33)[TEAPS](2)PW(12)O(40), exhibited satisfactory performance in the dimerization of rosin to prepare polymerized rosin Under optimum conditions (15.0 g rosin and 5.0 g Sm(0.33)[TEAPS](2)PW(12)O(40) catalyst in 18.0 mL toluene at 90 °C for 10 h), a polymerized rosin product with a softening point of 120.1 °C was obtained. In addition, the Sm(0.33)[TEAPS](2)PW(12)O(40) catalyst maintains excellent catalytic performance over five recycles.
