The acylation of long chain aliphatic primary amines

Abstract A method of acylating long chain primary aliphatic amines is described. Representative series of N‐monoalkylstearamides, N,N′‐dialkyladipamides and N,N′‐dialkylsebacamides, in which each alkyl radical contains between 8 and 18 carbon atoms, have been prepared by acylating the long chain primary amine with the corresponding acid amide. The products are all wax‐like substances. The N,N′‐dialkyladipamides and N,N′‐dialkylsebacamidcs are extremely stable substances; they have relatively high melting points (60°‐145°) and may be used in place of some of the more expensive natural waxes.
