Abstract
Abstract Free-flowing inorganic ammonium or potassium salts are produced by adding to said salts a mixture of half-esters of sulfuric acid with isomeric nonanols. The salts can be handled (metered, stored, shipped) in an advantageous manner and may be used in a wide range of applications, for example for drying and catalytic purposes and for use as additives to animal feeds.
