Purolite CT175 is a superior macroporous strong-acid catalyst resin which has been developed from poly(vinylbenzenesulfonate) cation exchangers. While ordinary commercial styrene-based sulphonic acid resins may often be used for chemical reactions catalysed by the H+ ion, faster process times, better yields and higher product purity may be obtained by using a properly designed and purified catalyst resin such as Purolite CT175. It is supplied either completely water-swollen, or dried to less than 3% moisture, ready for use.

Purolite CT175 has been specially designed with large pores for greater accessibility to the acid sites. The more rigid structure ensures improved uptake but lower swelling characteristics in polar solvents compared with competitive materials, resulting in a higher concentration of acid sites. This resin is particularly useful in diffusion-controlled or kinetically-limited reactions.
Purolite CT175 has been qualified and recommended for tertiary alkyl methyl ether (TAME) in particular, methyl tertiary butyl ether (MTBE). It offers distinct advantages over other commercially available catalysts with respect to its high acidity and large pores which provide more available acid sites and minimise the potential for pore plugging.
