2-Phenylethylamine(2-PEA)is one of the main ingredients for stimulants.Therefore,it is necessary to limit its use and illegal trade by conveniently detecting 2-PEA vapour.Here,a QCM based 2-PEA gas sensor was construc...
It is still a formidable challenge to study CH2O + CH3·→ CHO + CH4 reaction in the gas phase by traditional dynamics, because of the large number of freedom degrees for the system. In this paper, direct dynamics,...
Treatment of denudatine 1 with 10% HCl soln. at 45-50℃ for 3 days leads to a pair of epimers 4A and 4B, Structures of 4A and 4B have been elucidated on the basis of chemical and spectral methods.
The struetural effect of the conjugative system(C)with carbonyl-imino bridges has been studied.The results show that:In the conjugated system(C),there is no electronic absorption peak attributable to the whole system,...
Two new cornpounds,saponin I and saponin II,were isolated from Gynostemma longipes f.Y.Wu. The struetures have been characterized on the basis of cbenical and speetroseopie evidence. ^-~.
