Saponification of Diethyl Adipate with Sodium Hydroxide Using Reactive Distillation

This research presents a new study in reactive distillation by adopting consecutive reaction . The adopted was the saponification of diethyl adipate with NaOH solution. occurs two steps. process had role withdrawing intermediate product i.e. monoethyl from reacting mixture before second conversion to disodium occurred. It found that appeared successfully distillate liquid. percentage di-ester monoester greatly enhanced (reaching 86%) relative only 15.3% for case without .This means 5 times enhancement presence layers both and residual liquids noticed ,the upper (water) layer lower (ester) layer. However, water dominant .The excess solution calculated respect concentration (9%-79%) it increasing solution( until 40%) led increase monoester. also get pure made liquid appear as one Maximum been occurred rang (40%-60%). After 60% lowered noticeably.
