| Abstract: | With heteropoly acids as catalyst,diisooctyl glutarate was prepared by esterification of isooctyl alcohol and glutaric acid separated from dicarboxylic acids.Effects of alcohol acid ratio,reaction temperature, reaction time and the amount of catalyst were investigated.The optimum reaction conditions are the molar ratio of alcohol acid of 2 5∶1,reaction temperature of 140 ℃,reaction time of 120 min and the amount of catalysts of 0 2% of total mass of the system,under which the yield of dioctyl glutarate is greater than 99%.The IR spectrum, 1H NMR spectrum and elementary analysis were made,some performance indications of density,viscosity,index of refraction etc.were determined,and the application experiment in the outer protective material of PVC cable was given. |
| Keywords: | heteropoly acid glutaric acid isooctyl alcohol diisooctyl glutarate esterification |
