실험 절차
182 g of 2,2,6,6-tetramethyl-4-hydroxy-4-cyanopiperidine, 284 g of isononyl-aldehyde and 200 g of concentrated sulfuric acid are stirred for 25 hours at 60° C. in 600 g of glacial acetic acid in a 2 liter apparatus with agitator. After cooling the main portion of the solvent is distilled off under reduced pressure. The residue is stirred with 500 ml of acetone and suction-filtered, thus yielding 292 g=69% of th. of the sulfuric acid salt of the intended compound.
