固体酸催化酯化的研究─—对苯二甲酸辛酯的合成

Study on Catalytic Esterification with Solid Acids Synthesis of Dioctyl p-Phthalate

用半经验方法ＣＮＤＯ／２计算了对苯二甲酸等羧酸分子的结构，讨论了对苯二甲酸分子的结构特点，探讨了以Ｎａ＿２ＳＯ＿４－Ａｌ＿２Ｏ＿３体系催化对苯二甲酸辛酯的合成。

The structure of phthalic acid has been calculated using the CNDO/2 molecular orbitaltheory,in spoial,for p-phthalic acid the structure information and ability to react with ROH aredeeply dlscussed,and jet,Al_2O_3-Na_2SO_4,as catalytic system,the active function to the reaction arestudied,meanwhile,with it,dioctyl p-phthalate is synthesized.
