SEPLITE® CT813
SEPLITE® CT813 is a strong acid, macroporous polymer with sulfonic acid functional group. It is very suitable to be used as heterogeneous catalyst for organic reaction. The macroporous structure enables larger molecules enter the active part better. When it is used in the medium with higher polarity, the catalyst will perform better.

SEPLITE® CT813 Strong Acid Resin 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.
