| Abstract: | The optimum conditions have been studied on which the pentaerythritol (A) and adipic acid (B) and valeric acid (C) are esterified into dipentaerythritol Hexa(n-valeric acid) monoadipic acid ester in the presence of heteropoly acid (salt) catalyst.The catalyst is 0.8%of feedstock,the mole ratio of A to B to C is 1.0∶0.3∶5,the reaction time is 3 hours and reaction temperature is 140 ～150℃.Under the optimum conditions the yield of ester are above 93%. |
