| Abstract: | The catalytic activity of some solid acids in esterification of diisopentyl oxalate is reported. Both ZnSO 4 and Ti(SO 4) 2 show good catalytic activity in the esterification. Optimum conditions are as follows: oxalic acid 85mmol, isoamyl alcohol 238mmol, ZnSO 4 and Ti(SO 4) 2 0.8g, refluxing for 1.5h. The yield of esterify is 97.5% and the catalyst can be recovered easily and reused many times. |
