| Abstract: | Tetramethyl 1,4 dihydroxypoperidine(TMHPNOH)is synthesized.Its stability to heat and oxygen is examined.The relationship is discussed between its properties and molecular structure.It is found that during the flocculation of the compound from benzene solution in the existence of a small amount of H 2O a significant change of its 1H NMR spectra occurs,and the temperature effect is noticed,from which a valuable dynamic study method of the phase separation such as flocculation,crystallization,etc,might be suggested. |
