Disclosed is a high yield process for preparing di-substituted imidazoline fabric conditioning compounds. In this process, an acylating agent such as fatty acid is reacted with a specific polyamine, and the product of this reaction is thereafter reacted with either a fatty acid ester or glyceride under specifically-defined conditions and in the presence of an esterifying catalyst such as titanium alkoxide. Use of particular reaction conditions and an esterification catalyst significantly increases the yield of di-substituted imidazoline compounds.
