Abstract
Prepn. of 2,2,6,6-tetramethyl -4-oxopiperidine (I) comprises reacting acetone with ammonia in the presence of a cationic exchange resin and 0.001-1% (on wt. of resin) of EDTA, Na2EDTA and/or dimethylglyoxime. Reaction is pref. at 40-55 deg.C. - Typically, cation exchange resin, complexing agent and a soln. of NH3 in acetone are charged to a reactor, heated for 4-6 hr., cooled, and decanted. (I) is isolated by fractional distillation, boiling at 102-105 deg.C/18 mmHg.
