ALDEX Catalyst Series

C-15H MP High Activity Catalyst

Aldex C-15H MP is a macroreticular, strongly acidic, cation solid acid catalyst. Its open pore structure makes it an excellent catalyst for a wide variety of organic reactions. Aldex C-15H MP has a unique acid functionality which results in higher thermal stability versus standard catalysts. Further, large pores allow for easy ingress and egress of ions to access sulfonic acid sites. The S-DVB matrix is highly cross-linked and is resistant to oxidants and breakdown caused by mechanical and osmotic shock.

C-15 H MP Features

Uniform Particle Size

98% of all beads are in the minus 16 to plus 40 mesh range giving a lower pressure drop while maintaining the superior kinetics of standard mesh size products.

Superior Physical Stability

90% plus sphericity and high crush strengths together with a very uniform particle size provide greater resistance to bead breakage while maintaining low pressure drop.


Aldex C-15H MP is a superior next generation catalyst used in the production of MTBE and TAME and significantly outperforms conventional catalysts. With Aldex C-15H MP you may be able to operate at higher flow rates thereby increasing productivity with no major impact on the catalyst performance in terms of conversion.
