It can isolate oxonium ion (H7O3)+ salts, particularly from tetrachloroauric acid solutions, and catalyzes the O-alkylation of sodium salts of carboxylic acids in penicillin and cephalosporin series, aiding esterification without acid. Additionally, it facilitates the Williamson synthesis of ethers with hindered alcohols and sodium hydride.
