SEPLITE® CT-21A weak basic polymeric catalyst resin for remove acidic materials from organic solvents
SEPLITE® CT-21A is a weak base anion ion exchange resin based on the matrix of styrene-DVB copolymers.
It can be used to remove acidic materials from organic solvents and remove phenol from benzene and inhibitors from monomers like hydroquinone, hydroquinone mono-ethyl ether (MEHQ), tertiary butyl catechol (TBC).

Weak Basic Polymeric Catalyst 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 wet and may cause an exothermic reaction. Spilled materials may be slippery.
