“…This conclusion is in agreement with the recommendations made by Filachione and Fisher. 15 Moreover working with a dilute feed stream would increase the volume of the equipment used in the recovery unit. The cost reduction due to smaller equipment has to be compared with the additional cost due to the evaporator.…”

Lactic acid, being virtually a non-boiling compound, is difficult to separate from its aqueous solution by conventional methods such as distillation. It is necessary to convert it to the relatively volatile ester and the separation of the ester, followed by hydrolysis, is recommended as an appropriate method of recovery. In the present work, we explore and investigate a novel reactive distillation strategy to perform esterification, distillation and hydrolysis in a single unit. The experiments were performed in a batch reactive distillation set-up and the results have been explained with the help of an appropriate model. An unsteady state mathematical model based on an equilibrium stage concept was developed for batch reactive distillation. A pseudo-homogeneous model was used for the determination of reaction kinetics. The effect of operating parameters such as feed concentration, mole ratio, catalyst loading, boil-up rate, etc. on the recovery of lactic acid was studied with the help of simulation and experimental results. The feasibility issue of reactive distillation has been discussed based on the results obtained.

“…The modifying hydrophilicity, degradability, and breaking elongation of PLA were reviewed [3][4][5]. To do this, modifying the bulk and surface of PLA by introducing hydrophilic and biocompatible components and by adjusting the surface energy, surface charge, and surface roughness were described [4][5][6][7][8].…”
