Abstract

A modification of our previously reported^2^ gas chromatographic method of preparing vinyl‐^14^C~2~ chloride (^14^C‐VC) has been made. The procedure using 1,2‐dichloroethane‐^14^C~2~ obtained from New England Nuclear Corporation gave good yields of ^14^C‐VC as a gas mixture with helium.

The radiochemical purity of a representative sample of the ^14^C‐VC was determined by gas chromatography. Sequential fractions were trapped from gas chromatographic columns in a toluene based liquid scintillator. The radioactivity‐time profile was correlated with the retention time of authentic VC gas. A mass spectrum and a high resolution infrared spectrum obtained on the same sample of ^14^C‐VC were identical to spectra of authentic VC. The major radioactive impurity appeared to be acetylene.
