3. Manufacturing Process Flow: Precision & Quality Control

Stepwise Schematic: Manufacturing of Hegrecat MC112 (Dibutyltin Dilaurate)

1. Raw Material Intake: Pharmaceutical-grade dibutyltin oxide and lauric acid sourced from ISO-certified suppliers are intensively screened for purity (≥99.8%).
2. Esterification (Reactors): Reactants are heated (120-140°C) under inert nitrogen atmosphere, catalyzed for precise conversion, monitored via GC analytics.
3. Intermediate Filtration: Molecular sieves remove water; continuous filtration ensures removal of traces and enhances clarity (using 1–3 micron filters).
4. Purification (Distillation): Fractional vacuum distillation (
5. Stabilization: Addition of proprietary antioxidants enhances shelf life and protects catalytic sites from hydrolysis.
6. Final QC/Packaging: Each batch is sampled; characterized by HPLC, ICP-MS, and FTIR per ISO 9001:2015 procedures, then packaged under nitrogen in fluorinated drums.

• Material Sourcing → Reactor Synthesis → Filtration → Distillation → Quality Control → Nitrogen Packaging
• Key Advantage: All process nodes comply with ISO and ANSI standards, ensuring traceability from raw material to finished product.
