Methods of removing alkyl alkanesulfonate esters from aqueous or anhydrous compositions are provided. The invention provides methods for the conversion of alkyl alkanesulfonate esters of the formula RSO3R′ to the corresponding acids of the formula RSO3H. The alkyl alkanesulfonate esters are present in an organic medium, which may contain significant amounts of water or which may be anhydrous or substantially anhydrous. In some embodiments, the invention provides methods for purifying aqueous or anhydrous alkanesulfonic acids by removing alkyl alkanesulfonate esters.

The attachment of a hydroxymethylcryptand to lightly loaded chloromethylpolystyrene (1 mequiv of Cl/g) cross-linked with divinylbenzene leads to polymer-supported cryptands that are highly efficient catalysts in anion-promoted reactions carried out under phase-transfer conditions.However, the condensation with polystyrenes having a higher content of chloromethyl groups occurs in low yields, apparently affording immobilized cryptands with very low catalytic activity.This behavior results from extensive structural modifications of the bicyclic ligand, most likely promoted by neighboring chloromethyl groups.
