A Note on the Mechanism of the Formation of Alpha-Acylamino Ketones from Amino Acids

The reaction of alanine-1-C14 and phenylalanine-1-C14 with acetic anhydride in the presence of pyridine has been studied and the carboxyl group of the amino acid has been shown to be the exclusive source of carbon dioxide involved.

Summary of the Research Progress Meeting of March 9, 1950

The design of the present time of light mass spectrograph is similar to that of the isotron devised some time ago for isotope separation. The spectrograph will employ the time of flight principle only for the isotopic analysis of small samples.

Continuous injection processing (open access)

Continuous injection processing

From introduction: "In this report we consider a few non-adiabatic processes. The types to be discussed will be limited because of two reasons: first, complete descriptions are available for some processes; second, as time goes on alternative injection methods undoubtedly will be discovered, so this list must necessarily be incomplete."
