Abstract he catalytic hydrogenation of 2,2,6,6tetramethyl4piperidone to 2,2,6,6tetramethyl4piperidinol was studied in the present paper.The reaction conditions,including nature of catalysts,concentration of triacetone and solvents,etc.,were investigated systematically when the reaction was carried out in a fluidizedbed tower reactor.The reaction parameters were optimised.The yield of 2,2,6,6tetramethyl4piperidinol is up to 97% under optimum reaction conditions.Thus,a novel route to synthesize 2,2,6,6tetramethyl4piperidinol by catalytic hydrogenation of triacetoneamine was established.
