| abstract | The present invention provides a method of preparing a sulfonyl ether comprising the steps of: v) reacting a sulfonic acid with an anhydride, under continuous vacuum distillation conditions, to form a carboxysulfonate; vi) reacting the carboxysulfonate with an optionally substituted cycloalkane ring containing at least 3 heteroatoms to form a sulfonyl ether pre-mix comprising a sulfonyl ether and at least two additional reaction products each containing at least one ether linkage; vii) subjecting the pre-mix to continuous vacuum distillation conditions to remove at least some of the additional reaction products from the sulfonyl ether pre-mix to provide a crude sulfonyl ether product; and viii) purifying the crude sulfonyl ether product. |
