LEWATIT® K 1161

Lewatit® K 1161 is a gel-type, polymer-based resin in spherical bead form with strongly acidic sulfonic acid groups. It possesses a monodisperse particle size distribution, i. e. beads of almost the same size. Due to its low degree of cross-linking and high mechanical stability it is ideally suited for the processing of liquid organic media, especially in the following applications:

• Bisphenol-A production
• Condensation and esterification of small polar molecules
• Hydrolysis of ethers and esters
