Synthesis and properties of alkyl phosphate based antistatic agent

Antistatic agents of alkyl phosphate were synthesized with aliphatic alcohol and P_2O_5 as main materials.Firstly,the synthesis conditions were discussed by orthogonal experiments.The results showed that stable products with high conversion rate can be obtained when esterified under(80 ℃) for(5 h,) hydrolyzesdat(70 ℃) for(2 h,) with diethanolamine as neutralization agent.The effect of n(dodecyl alcohol)∶n(octadecanol)on the yield under given conditions was small,but the product′s moisture absorption increased and heat resistance decreased as octadecanol increased,while the product′s antistatic property was best when n(dodecyl alcohol)∶n(octadecanol)was 2∶1.
