Manufacturing Process Flow: Precision & Quality Control Stepwise Schematic: Manufacturing of Hegrecat MC112 (Dibutyltin Dilaurate) Raw Material Intake: Pharmaceutical-grade dibutyltin oxide and lauric acid sourced from ISO-certified suppliers are intensively screened for purity (≥99.8%). Esterification (Reactors): Reactants are heated (120-140°C) under inert nitrogen atmosphere, catalyzed for precise conversion, monitored via GC analytics. Intermediate Filtration: Molecular sieves remove water; continuous filtration ensures removal of traces and enhances clarity (using 1–3 micron filters). Purification (Distillation): Fractional vacuum distillation (<12 mmHg) isolates pure dibutyltin dilaurate while separating residuals. Stabilization: Addition of proprietary antioxidants enhances shelf life and protects catalytic sites from hydrolysis. 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. 4.
