A tenfold mass production scale-up that provides an economical synthesis method for producing normal-heptafluoropropyl iodide (n-C3F7I) laser "fuel'' sustaining stable and reliable cw atomic iodine lasing at 1.315 μ via UV photolysis is reported. Such results strongly indicate that high purity n-C3F7I is being synthesized. Over 1 kg per day production of this n-C3F7I is demonstrated. The synthesis procedure involves three steps: formation of the n-C3F7COONa salt, refluxing at 45 °C, and a packed column distillation. During the synthesis, particular attention is given to minimizing those impurities producing detrimental effects on atomic iodine lasers. Yields of 65%–75% for n-C3F7I laser "fuel'' are achieved whenever liquid nitrogen is used to collect the synthesized product.
