http://wcrc.confex.com/wcrc/2007/techprogram/P1801.HTM WebWe have found that esterification of cotton cellulose by BTTA takes place only when NaH 2 PO 2 is present and the temperature is above 180°C. Therefore, the catalysis effects of NaH 2 PO 2 for cotton esterification by BTTA are probably related to the reaction between NaH 2 PO 2 and the anhydride intermediate.
