Featured researches published by Thomas A. Elwood.


Journal of The Chemical Society B: Physical Organic | 1970

Dehydration of the protonated butane-2,3-dione–ethanol ion [(CH3CO·-CO·CH3)(C2H5OH)H+] in the gaseous phase

Thomas A. Lehman; Thomas A. Elwood; Michael K. Hoffman; Maurice M. Bursey

Among the ions present in the ion cyclotron resonance spectrum of a mixture of butane-2,3-dione and ethanol at low ionizing voltage is a species of m/e 115 which is shown by deuterium labelling to correspond to a product of dehydration of the mixed-solvate (CH3COCOCH3)(C2H5OH)H+ in which both hydrogen atoms lost originate from the hydroxy-group of ethanol.
