Wan, Wen-jing published the artcileImprovement of 2,2,6,6-tetramethyl-4-piperidinamine synthesis via catalytic amination, Product Details of C9H17NO, the publication is Gaoxiao Huaxue Gongcheng Xuebao (2020), 34(2), 457-462, database is CAplus.
2,2,6,6-Tetramethylpiperidinamine as light stabilizer of hindered amines was synthesized via catalytic amination of 2,2,6,6-tetramethylpiperidone. Imine formation was promoted by adjusting reaction system pH, which facilitated the catalytic amination under mild condition. The selectivity of the product was increased. When studied under pH∼12.5, reaction temperature 60°C and pressure 2 MPa, the selectivity of TEMP was up to 95.2%. The result shows that pH=12.5 is the most favorable condition for the formation of TEMP.
