| Abstract |
The synthesis of DDT labeled with carbon-14 in the tertiary position was carried out in the following steps: barium carbonate to ethyl acetate to ethyl alcohol to chloral to DDT. Starting with 50 millimoles of barium carbonate containing 20 millicuries of activity, 15 grams of crude DDT were obtained (42% yield based on ethyl alcohol). Two crystallizations from ethyl alcohol yielded 6.11 grams of p,p'-DDT (17% yield) having a melting point of 107-107.5 degrees C. The specific activity was approximately 0.5 millicurie per gram. |
