Normally liquid, omega-hydrofluoroalkyl ether compounds (and selected mixtures thereof) have a saturated perfluoroaliphatic chain of carbon atoms interrupted by one or more ether oxygen atoms. The compounds can be prepare, e.g. by decarboxylation of the corresponding fluoroalkyl ether carboxylic acids and are useful, e.g., in cleaning and drying applications.
通常是液体的ω-氢氟烷基醚化合物(及其选定的混合物)具有由一个或多个醚氧原子中断的饱和全氟脂肪链的碳原子。这些化合物可以通过相应的氟烷基醚羧酸的脱羧反应制备,例如在清洁和干燥应用中很有用。
