| Abstract: | Upon heating of 2,4,5-T to 600°C, 2,3,7,8-TCDD is formed with a yield of 0,2 %. At 800°C, the formation of TCDD decreases by a factor at 200. Tormona 80® an ester at 2,4,5-T yields 200 ppm TCDD at 600°C and 3 ppm at 800°C. The highest formation rate is observed for 2,4,5-Trichlorophenol (0,5 % at 600°C). During the thermolysis of 2,4-D, γ-Hexachlorocyclohexane, 2,4,6-Trichlorophenol, Pentachlorophenol and Clophen A 40. 2,3,7,8-TCDD could not be detected. |
