Evaluation of the mass spectrometric patterns of volatile liquid anaesthetics to predict the temperature - metal caused decomposition pathway
(Elsevier Science Bv, 2003)
In this study, prediction of the thermal decomposition pathway of the volatile liquid anaesthetics such as halothane, enflurane and isoflurane in contact with various metal/metal oxides at elevated temperatures has been ...
Bis(2-aminopyridinium) maleate
(Blackwell Munksgaard, 2003)
Two cyclic eight-membered hydrogen-bonded rings exist in the title compound, 2C(5)H(7)N(2)(+).C4H2O42-, involving the 2-aminopyridinium and maleate ions. The dihedral angle between the two pyridinium rings hydrogen bonded ...
