Esterification and Polycondensation Parallel Reaction Apparatus

The esterification–polycondensation parallel reaction apparatus is primarily used to evaluate and study process conditions, explore optimal process parameters, and, through analysis, evaluation, and data processing, obtain data on product distribution, product properties, and other relevant metrics—providing foundational design data for experimental process development. Esterification and polycondensation are carried out in the same reactor, each equipped with a dedicated water‑and‑alcohol distillation system and corresponding collection vessels; the reactor is designed with a quick-flange configuration.

Product Description

Application Scenarios

1. Polymer Materials Research and Development

Biodegradable polyester (PLA/PBS) Optimize esterification time and polycondensation vacuum to balance molecular weight and color.
High‑performance engineering plastics (PET/PBT) Study the effects of catalysts (such as tetrabutyl titanate) and vacuum segmentation on the polycondensation rate.

2. Fine Chemical Process Development

Coating resin (alkyd resin) Evaluate the impact of polyol/acid ratio and drainage efficiency on the resin acid value.
Plasticizer (DOTP) Explore the correlation between azeotropic dehydration during the esterification stage and the conversion rate of phthalic anhydride during the polycondensation stage.

3. Academic Research and Teaching

Reaction Engineering Laboratory Experiment Demonstrate the kinetic differences between esterification and polycondensation, and train students’ ability to regulate multiple parameters in a coupled manner.
Research on Green Processes : Verify the atom economy of vacuum-driven reactions under solvent-free conditions.

4. Bridging Small-Scale and Pilot-Scale Testing for Enterprises

Process Package Development Provide the critical parameters required for scaling up (such as the end-of-polycondensation torque and the vacuum decay curve) to reduce industrialization risks.
Fault Simulation By artificially setting abnormal conditions (such as vacuum leaks), we can study their impact on the molecular weight distribution of the product.
