Features Of Johnson Matthey JM812 Catalyst

  1. Highly selective palladium-based formulation optimized for low-temperature hydrogenation reactions.

  2. Thermally stable support structure enabling consistent performance across extended operational cycles.

  3. Controlled metal dispersion ensures reproducible activity and reduced risk of over-hydrogenation.

  4. Low leaching profile under standard process conditions, supporting compliance with stringent pharmaceutical purity requirements.

  5. Available in standardized pellet form for seamless integration into fixed-bed and trickle-bed reactor systems.

Typical Applications Of Johnson Matthey JM812 Catalyst

  1. Hydrogenation of unsaturated nitroaromatics to corresponding anilines in fine chemical synthesis.

  2. Selective reduction of alkynes to cis-alkenes in pharmaceutical intermediate manufacturing.

  3. Catalytic deprotection of benzyl and Cbz groups under mild hydrogenation conditions.

  4. Continuous-flow hydrogenation processes requiring high catalyst longevity and minimal fouling.

  5. Production of high-purity agrochemical intermediates where metal residue limits are strictly enforced.
