encapsulated catalysts

Which are NON-PYROPHORIC and NON- LEACHING. They are ‘easier, cleaner and safer’
catalysts which minimize consumption and loss-in-process of high value precious or base metals by
encapsulating them within an inert polyurea matrix.

TM
Some advantages of EnCat system are:
 Safer-non-pyrophoric  Reduced leaching - Metal remains within the beads
 Increased Yields /Selectivity  Easier to handle - Reduce exposure to toxic metals
 Used in Batch and Flow mode  Recyclable - Can be reused for multiple cycles
 Overall Cost Reduction  Fast, efficient processing - Easy filtration & reduce work-up

TM
Reaxa’s EnCat Product line includes:
 Nickel EnCat TM
 Palladium(0) EnCat TM
 Palladium(II) EnCat TM
 Platinum(0) EnCat TM

 Osmium(VIII)EnCat TM
EnCats finds its use in catalytic processes involving HYDROGENATIONS / C-C COUPLING REACTIONS/
TM
DIHYDROXYLATIONS in the pharmaceutical, agrochemical, fine chemical and specialty chemical fields.
They have been successfully used for intermediates like Sulfolane, ATS 9(ATORVASTATIN), CHEA
(DEXTROMETHORPHAN) & Intermediates for MONTELUKAST, PENAMS, DABIGATARAN and many more…

Reaxa’s immobilization technology is patented and can be used to encapsulate customer specific catalyst.
EnCat™ products are tailored to meet the specific requirements of a particular chemical transformation by
varying the polymer bead structure (porosity, rigidity, size), the metal loading and co-encapsulated ligand type,
addition of promoters or concentration.

TM
Reaxa is developing other base metal catalysts like Nickel for Suzuki reactions and Cobalt EnCats for
selective reduction reactions of Nitro compounds as replacement of Pt/C.
