<p>Secondary etheramine acetates of the formula <IMAGE> I in which R is alkyl or alkenyl having from 7 to 24 carbon atoms, cyclohexyl or aryl optionally substituted by alkyl, X and Y represent hydrogen or methyl, but are not both methyl at the same time, and n is an integer in the range of from 2 to 20. They are obtained by reacting secondary etheramines of the general formula <IMAGE> IN WHICH R, X, Y and n are defined as above, with glacial acetic acid. These compounds are used as lubricating agents in the preparation and processing of synthetic fibers.</p> |
