Procedure

The procedure described in Example I was repeated except that octadecylamine (Armeen 18D) was substituted for n-dodecylamine and the product was stripped of water and excess butyrolactone and was discharged at about 75° C. to provide 96% pure N-octadecyl-2-pyrrolidone solid in a yield of 96%.

Workup

  1. customwas discharged at about 75° C.
