Procedure
A misture of 13.0 parts of 4-dodecyloxy-2,2,6,6-tetramethylpiperidine and 3.42 parts of benzyl bromide was heated at 100° C. for 48 hours. Petroleum ether (b.p. 40°-60° C.) was added to the cooled reaction mixture and the 4-dodecyloxy-2,2,6,6-tetramethylpiperidine hydrobromide formed during the reaction was filtered off. The petroleum ether solvent was removed by distillation under reduced pressure and the residue fractionally distilled to give 4-dodecyloxy-1-benzyl-2,2,6,6,-tetramethylpiperidine having a boiling point of 200° C. at 0.5 m.m. of Hg. and the following elemental analysis by weight:
