【摘要】 以苯酐和2乙基己醇为原料,在自制的TiO2/Al2O3复合型催化剂上合成邻苯二甲酸二异辛酯,确定了反应中催化剂的最佳配比,并通过正交设计探讨了原料配比、催化剂用量、反应温度对酯化反应的影响更多还原

【Abstract】 The synthesis of de(2 ethylhexyl) phthalate was perfrmed by esterification of 2 ethylhexyl alcohol and phthalic anhydride in prepared compound catalyst TiO 2/Al 2O 3 Atomic ratio of catalyst was defined,and factors to influence esterification was developed by a serial of experiment,such as ratio of 2 ethlhexyl alcohol to phthalic anhydride,amount of catalyst,reaction temperature更多还原
