Abstract: | By photochemical dissociation of the rare carbon isotope component of CHClF2 by means of a CO2 laser with an average power of 150 W, Q-switched at 10 kHz, we have demonstrated the separation of more than 1 mol of 13C, enriched to 50% (2 mol of total carbon). It is contained in about 1 mol (101 g) of the product C2F4. The total throughput of the starting material was 29 kg. The experiment was run day and night for 2 weeks, almost only controlled by a computer. We obtained production rates of 5 mmol/h, corresponding to about 0.5 kg 13C per year. |
