Similarly, a comparable diamine, presumably obtained from Rosin Amine D and acrylonitrile, can be prepared. The structure of Rosin Amine D is as follows: STR14 Polyamines from monoamines and cyclic imines, such as ethylene imine. STR15 N-octyl ethylenediamine STR16 N-tetradecyl ethylenediamine STR17 N-hexadecylethylenediamine STR18 N-dodecyl triethylenetetramine STR19 N-dodecyl propylenediamine STR20 N-decyl butylenediamine |

EXAMPLE 1 This example illustrates the preparation of n-octylimidazolidone. The starting diamine, N-n-octyl ethylene diamine was prepared from n-octyl chloride and ethylene diamine (Linsker and Evans, J. Am. Chem. Soc. 1945, 67, 1581-1582). This diamine (9.95 g, 0.058 mol) was reacted with urea (3.5 g, 0.058 mol) in a 50 mL 3-neck round bottom flask. The flask was equipped with a nitrogen inlet to flush the ammonia produced in the reaction out of the system and into a trap (dilute sulfuric acid). Ammonia evolution commenced at about 140 C. and heating was continued to 210 C. The temperature was held at this level for two hours to assure ring closure to the cyclic product. A small amount of material was sublimed from the reaction residue to give a white crystalline solid (mp 42.0-42.4 C.) which was used for all further measurements. |
