ABSTRACT:
This invention is a method for making 1,2-substituted imidazoline compositions utilizing a polyamine mixture containing a high concentration of linear polyamine. The polyamine is either triethylenetetramine or tetraethylenepentamine. The polyamine mixture is reacted with a fatty acid, fatty dimer acid or the fatty esters thereof to yield the 1,2-substituted imidazoline composition. The highly linear polyamine provides higher yields of the imidazoline compound in the composition.
