【Abstract】 The present paper deals with the esterification of pentaerythritol with aliphatic acids and C5-9 mixed acid. The influencing facters of esterification and properties of the pentaerythritol esters were studied. The results showed that the esterification products of octanoic acid and C5-9 mixed aicd are suitable to use as dielectric fluid with low flammability, such as transformer oil, switch oil,capacitor fluid and other dielectric fluids.The flash point is >240℃, pour point<-40℃ and breakdown voltage >35 kV/cm.
