Ammonium caprylate is a chemical compound with the chemical formula C8H19NO2. [1] This is an organic ammonium salt of caprylic acid. [2]

Contents

Synthesis

Ammonium caprylate can be prepared by reacting caprylic acid and ammonia. [3]

Physical properties

Ammonium caprylate forms hygroscopic crystals of the monoclinic system.

It can be easily hydrolyzed by water. It is soluble in glacial acetic acid and ethanol; less soluble in methanol; slightly soluble in acetone and ethyl acetate; and practically insoluble in chloroform or benzene. [4]

Ammonium caprylate loses ammonia slowly in dry air, but this process is accelerated in humid air. [5]

Uses

The compound is used to produce photographic emulsions, also as an insecticide and nematocide, and in manufacturing of zinc caprylate. [6] In the food industry it is used as an emulsifier, stabilizer, and anticaking agent. [7]
