Abstract
1,210,691. N-Stearyl amides. FARBENFABRIKEN BAYER A.G. 4 Jan., 1968 [10 Jan., 1967], No. 649/68. Heading C2C. [Also in Divisions B2 and C3] Stearyl isocyanate may be reacted with (i) stearylamine, (ii) N,N-dimethyl-hydrazine or (iii) 1,4-butanediol to form respectively N,N<SP>1</SP>- distearyl - urea, 1,1 - dimethyl - 4 - stearyl semicarbazide and the bis-urethane C 18 H 37 .NH.CO. O(CH 2 ) 4 .O.CO.NH.C 18 H 37 . Hexomethylene-bis-stearylarea may be prepared by reacting stearylamine with hexane-1,6- diisocyanate.
