Циклооктиламин

Description

Cyclooctylamine is a primary aliphatic amine with an eight-membered carbon ring. It is used as an intermediate product in the synthesis of pharmaceutical substances and agrochemical active ingredients. Cycloalkylamines with rings of 5-10 carbon atoms, including the cyclooctyl series, are considered suitable raw materials for corrosion inhibitor formulations, where the amino group is adsorbed on the metal surface and forms a protective film, and the bulky lipophilic cycloalkyl moiety increases the resistance of this film to leaching by the aqueous phase. The basicity and good solubility of the primary amine in water facilitate its inclusion in aqueous and water-oil compositions for protecting metals from corrosion. Compared to shorter cycloalkylamines (cyclopentyl-, cyclohexylamine), the enlarged eight-membered cyclooctylamine ring increases the lipophilicity of the molecule, which enhances the adsorption of the protective film on the metal surface.

Scope of application

An intermediate product in the synthesis of pharmaceutical substances and agrochemical active ingredients. A potential raw material for the formulation of metal surface corrosion inhibitors: the amino group adsorbs onto the metal to form a protective film, and the bulky cyclooctyl moiety increases the film's resistance to water washout. The good solubility of the amine in water (10.2 g/l) facilitates the inclusion of the substance in aqueous and water-oil technological compositions.
