Etherification of isobutene with methanol to produce MTBE
SEPLITE® CT101 MTBE Production

SEPLITE® CT101 is the solid strong acid catalyst for the production of MTBE (methyl tertiary-butyl ether) with the usage of sulfonic acid groups based on the matrix of styrene-DVB copolymer to form the proper pore structure. The technical performance of this polymeric catalyst have reached advanced level with its important features of high activity and long service lifetime.


SEPLITE® CT101 Catalytic Resins Keyfeaturesand benefits:

  • High total capacity, high conversion rate, and long catalyst lifetime

  • Proper pore structure, high sensitivity, good low-temperature activity

  • Excellent thermal tolerance and stability

  • Production adopted by full-automatic control system to guarantee the stable quality

SEPLITE® CT101 Catalytic Resins Precautions:

Resins should be stored in sealed containers or bags where temperature was above 0℃ in dry conditions without exposure to direct sunlight.
Do not mix ion exchange resin with strong oxidizing agents; otherwise it will cause violent reactions.
In case of eyes contact with resins, rinse eyes immediately with plenty of water, and consult a specialist. Material and samples must be disposed according to local regulations.
Dry polymers will expand when become wetted and may cause an exothermic reaction. Spilled materials may be slippery.
