Highly selective palladium-based catalyst optimized for hydrogenation of nitroaromatics and unsaturated aldehydes.
Engineered with controlled metal dispersion on high-surface-area activated carbon support for consistent activity and reproducible performance.
Low leaching profile ensures minimal metal contamination in final products—critical for pharmaceutical and fine chemical synthesis.
Thermally stable under standard batch and continuous-flow hydrogenation conditions (up to 100 °C, ≤10 bar H₂).
Supplied as a ready-to-use, pre-reduced catalyst—eliminates on-site activation steps and reduces process risk.
Hydrogenation of nitrobenzene derivatives to corresponding anilines in agrochemical intermediate manufacturing.
Selective reduction of α,β-unsaturated aldehydes (e.g., cinnamaldehyde) to saturated aldehydes in fragrance and flavor synthesis.
Catalytic conversion of nitrophenols to aminophenols for dye and polymer precursor production.
Batch and trickle-bed hydrogenation of functionalized heterocycles in API (Active Pharmaceutical Ingredient) manufacturing.

Q1: What is the primary function of ActiSorb 400 in polymer processing?
A: ActiSorb 400 is a highly active cobalt-based catalyst designed to accelerate oxidative crosslinking reactions—particularly in unsaturated polyester resins and vinyl ester systems—enabling faster gel times and improved cure efficiency under ambient or mild thermal conditions.
Q2: How does ActiSorb 400 compare to traditional cobalt naphthenate catalysts?
A: ActiSorb 400 offers enhanced reactivity and better storage stability compared to conventional cobalt naphthenates, with reduced sensitivity to moisture and improved compatibility in low-VOC and high-solids formulations. Its optimized dispersion profile also supports more consistent cure performance across varied batch sizes and mixing conditions.
Q3: Is ActiSorb 400 suitable for use in food-contact or potable water applications?
A: ActiSorb 400 is not intended for direct food-contact or potable water applications unless specifically validated and approved by the end-product manufacturer in compliance with applicable regulatory requirements. Formulators must conduct full regulatory assessment—including migration evaluation and final-use validation—prior to such deployment.
Q4: What are recommended handling and storage practices for ActiSorb 400?
A: Store in tightly sealed original containers at temperatures between 5 °C and 30 °C, away from direct sunlight and strong oxidizing agents. Avoid prolonged exposure to air or moisture. Use appropriate personal protective equipment (PPE), including chemical-resistant gloves and eye protection, during handling due to its cobalt content and catalytic activity.
