The thermal reactions of 2,4,6-T(3)CP in the presence and absence of DEHP in a dry air stream was investigated using a silica flow reactor at a residence time of 10s and a temperature range from 450 degrees C to 850 degrees C. Two isomers of T(4)CDDs (1,3,6,8- and 1,3,7,9-T(4)CDDs) were the most abundant products during the combustion of 2,4,6-T(3)CP alone and were observed at temperatures ranging from 550 degrees C to 800 degrees C. In the presence of DEHP, we observed a remarkable decrease in the yields of T(4)CDDs during the combustion of 2,4,6-T(3)CP. The suppression ratio of the T(4)CDDs formation was more than 90% in the case of the co-combustion with 10% DEHP in molar ratio. Other PCDD/Fs except for 2,7-/2,8-DCDD and 2,8-DCDF also decreased upon the combustion of 2,4,6-T(3)CP in the presence of DEHP. During the co-combustion of 2,4,6-T(3)CP and DEHP, the residual ratio of 2,4,6-T(3)CP increased slightly and formations of lower chlorinated phenols were observed. The suppression of the T(4)CDDs was strongly dependent on the DEHP ratio in the starting material. The prospective pathways of the suppressions of the T(4)CDDs formations during the combustion of 2,4,6-T(3)CP in the presence of DEHP were proposed.
